A commonly occurring problem with well water… the smell of rotten eggs in the water. Not a pleasant smell at all and in some cases the smell can nearly knock a person over when the concentration gets too high.

What causes that rotten egg smell in water? Usually it comes from the presence of dissolved hydrogen sulfide gas and it takes very little of the gas to make water smell bad. Less than 1 ppm will make water practically undrinkable.

The fact that you can smell the dissolved gas will not give you enough information to choose the correct water filtration system. Every system has a limit as to how much hydrogen sulfide gas it can remove and not getting the right size system may result in the rotten egg smell in your water not going away… and that would suck, right?

With whole house water filtration systems designed to remove hydrogen sulfide (plus iron and manganese) costing over $1,000 most of the time, you DEFINITELY want to make sure you choose the right water filter system for your level of hydrogen sulfide contamination.

For the task of testing hydrogen sulfide we suggest you take a look at the Low Range Hydrogen Sulfide Test Kit made by SenSafe. It has a low detection level of just 0.3ppm, an upper detection limit of 2.0ppm hydrogen sulfide in water, and takes just 20 seconds.

In the event that your water has greater than 2.0ppm hydrogen sulfide, SenSafe’s Hydrogen Sulfide Test Kit has a low detection range of 5ppm and an upper detection limit of 80ppm hydrogen sulfide in water.

The upper detection limit of the SenSafe Hydrogen Sulfide Test Kit makes it useful for industrial water applications.

Thinking about starting a smoke detector testing campaign in your city? Need to outfit an entire city worth of fire inspectors with canned smoke?

Whatever the reason(s) for needing a whole lot of canned smoke in convenient 0.5 ounce containers, we think we can help. We found a company with the ability to sell canned smoke by the pallet load.

A pallet load of canned smoke contains 20 cases of 0.5 ounce cans and each case contains 288 cans. If you do the math, that amounts to 5,760 cans of canned smoke per pallet.

Why buy in bulk?

Organizations such as fire departments and real estate groups can save a LOT of money in the long run by purchasing canned smoke in bulk. Both groups have to test smoke detectors on a regular basis — and we don’t mean by simply pressing the little ‘test’ button, either — so why not stock up on a commodity item at a great price in the same manner as people do when they shop at BJ’s or Sam’s Club for toilet paper, napkins, soap, cereal, etc.?

I don’t need THAT much smoke detector tester…

Conveniently enough, TestProducts.Com also sells canned smoke check in smaller amounts… as low as just a single 0.25 ounce container that contains enough test reagent for 10+ smoke detector tests.

1/2 Ounce Smoke Check

1/4 Ounce Smoke Check

2.5 Ounce Smoke Check

• Automotive industry uses refractometers to analyze antifreeze and transmission fluids
• Wine growers use refractometers to measure the amount of sugar in their product at various times
• Environmentalists an use refractometers to measure the salinity (saltiness) of water.
• … and the list goes on.

Refractometers work on the principle of refraction, or the bending of the path of a beam of light as it passes through a medium of some sort. Different mediums will cause the light to bend in different amounts and thus a direct relation between concentration and changes in light path exists.

Ever have a problem w/ moisture ruining a loaf of bread prematurely? Or how about a colony of mold and/or mildew showing up on material that did not dry properly before getting folded up and put away?

Those problems do not COMPARE to the problems farmers go through if they do not keep accurate tabs on the moisture levels inside their hay and grain bales. If the levels get out of range, their crops can spoil and that means devastating financial problems for their business.

The GrainMaster comes with an integrated grinder-compressor unit that enables the user to take on-site moisture readings in ground samples quickly and easily.

Along with the GrainMaster, which comes in a handy carrying pouch, you also get a grinder-compressor unit, grain cup, sample spoon, brush and ‘Quickcheck’.

Besides having the ability to detect moisture levels from 0% to 100%, the GrainMaster has 15 pre-programmed calibrations for Wheat, Barley, Oats, Oilseed Rape, Canola, Linseed, Peas, Corn, Sunflower, Coffee, Soya, Rice, Sorghum, Paddy and Beans.

Need to test down inside a bale or down in a barrel? No problem. You can pick up optional probes for measuring temperature in stored grain (GRN6046) and moisture levels in baled hay and straw (GRN6138) as well.

Tony from Orlando asked, “What is the ASTM Test Method associated with testing the hardness of steel and what type of instrument is used?”

Well, Tony, we know of several different hardness scales including Shore A, Shore D, Rockwell, Vickers and Brinell. We imagine that you COULD measure hardness of steel using any of those scales, but we also know about ASTM A956 — Standard Test Method for Leeb Hardness Testing of Steel Products.

For those not familiar with ASTM A956, you can read a synopsis of the method’s purpose and scope below.

ASTM A956

Significance and Use

Hardness of a material is a poorly defined term that may have many meanings depending on the type of test performed and the expectations of the person involved. The Leeb hardness test is of the dynamic or rebound type, which primarily depends both on the plastic and on the elastic properties of the material being tested. The results obtained are indicative of the strength and dependent on the heat treatment of the material tested.

The Leeb hardness test is a superficial determination only measuring the condition of the surface contacted. The results generated at that location do not represent the part at any other surface location and yield no information about the material at subsurface locations.

1. Scope

1.1 This test method covers the determination of the Leeb hardness of steel, cast steel, and cast iron (Part A), including the methods for the verification of Leeb hardness testing instruments (Part B), and the calibration of standardized test blocks (Part C).
Note 1

The original title of this standard was “Standard Test Method for Equotip Hardness Testing of Steel Products.”

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

OK, so if you don’t already know what the term ‘wet bulb globe temperature’ means, don’t worry. We didn’t, either, before writing this blog entry.

The term refers to the way the human body ‘feels’ in response to actual temperature, real-time exposure to sunlight, and humidity. Many refer to the wet bulb globe temperature, often as WBGT, as heat index.

As the Summer months slowly start to creep into the Northern Hemisphere, and temperatures along with humidity readings begin to climb, industrial hygienists, athletic trainers, the military, Summer Camp administrators all over start to keep a close watch on the weather not just to make sure on one gets caught in the rain, but to make sure people under their charge don’t wind up getting heat stroke!

Instruments like the Heat Index Monitor Wet Bulb Globe Meter (WBGT8758) w/ 40mm Black Globe take the guesswork out of heat index monitoring and provide instant, on-the-spot heat index data.

Features of the Heat Index Monitor Wet Bulb Globe Meter (WBGT8758) w/ 40mm Black Globe include

• Ability to Measure Wet Bulb Globe Temperature (WBGT) – a commonly used heat stress indicator that considers the effects of temperature, humidity and radiant energy.

• Measures Black Globe Temperature (TG) – measured by the black globe thermometer, which monitors the effects of direct solar radiation on an exposed surface.

• Monitors Ambient Air Temperature (TA).

• Provides Real-Time Relative Humidty (%RH).

• Allows users to keep tabs on conditions in direct sunlight and out of direct sunlight at the same time.

• Audible Alarm Will Go Off When Conditions Exceed User Specified Limits.

With high school, college and professional sports getting more and more competitive all the time, some players will do whatever it takes to get an edge — even if it means breaking the rules and running the risk of getting kicked off the team or banned from competition.

Steroids provide a fast, efficient means of gaining muscle mass, gaining muscle strength and gaining a competitive edge… and they harm the human body in the process. For that reason most governing sports bodies have rules on the books outlawing the use of steroids by players and competitors.

In some sporting events, such as the Olympics, mandatory testing for performance enhancing compounds, including steroids) takes place randomly throughout the events and after each medal-winning victory.

But what about on high school football fields, basketball courts, and other athletic venues where steroids ought not exist, but concerned parents may wonder about their children because of sudden increases in muscle mass, drastic reductions in body fat, and wild changes in attitude (not attributed to puberty… lol.)?

When that happens the parent, or other concerned party such as a coach or guidance counselor, may want to consider trying to get the athlete to consent to a home test kit for steroid use such as SteroidConfirm.

As a general rule, an innocent athlete will gladly submit to the test… and carry a chip on their shoulder about it afterwards, while a guilty athlete will throw up every objection in the book not to take the test and become hostile at the very notion that someone would think he/she has taken steroids.

Not a fun road to travel, this ugly steroid testing path, but if you love someone and want them to live a long life after they leave the playing field, sometimes it is the road you must travel.
