Any good gardener knows that plants will NOT grow at the right pace or the correct way without the proper balance of light around them, moisture in their soil, and the correct pH balance in their soil. While some folks naturally have a ‘green thumb’ and can get all three of those factors perfectly balanced w/o help from meters, the other 99% of us need help, so… below you will find soil pH meters, moisture in soil meters and light meters along w/ a few other handy gardening tools.

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.
Testing for… darkness? Huh? Why would someone do THAT?!?
Exactly our point. Few people really have a need to test for darkness. Most people do, however, have a need to test for light — especially people interested in taking the perfect picture, shooting the perfect video, or setting up a room in their home with perfect lighting.

And sometimes, when things don’t exactly work out as we plan, and darkness finds its way into our world due to unforeseen events, having the following device installed in our home or office will give us temporary light for a while until the power comes back on.

In the event that the power will take longer to come back on than you would like, perhaps you might need… a flashlight?
While no simple testing methods exist (yet) for detecting ‘bad’ Chinese Drywall, a person CAN make their life a little easier when trying to determine whether or not sections of already installed drywall may have come from China.
Depending upon what a person needs to do in order to get a look at the back of the drywall (the side facing the inside of the wall), one of the following tools may come in handy… and two of them will prevent that person from haing to cut a huge a huge hole in the wall, ceiling, etc.
Waterproof flashlights really come in handy when changing a car tire at night during a rainstorm, trying to fix plumbing problems under the sink or at night, walking the family dog on a cold, rainy night, or pretty much any time that a person needs to see in an moist environment.
So for those times when you don’t need a Light Meter to tell you that it’s dark and a Moisture Meter to tell you that you’re working in a wet environment, make sure you’ve got a reliable waterproof flashlight with fully charged batteries.
Note: One should not trust that traditional waterproof flashlights will work underwater for extended periods of time. They make highly specialized diving lights for that sort of thing!
All the right test equipment in the world will do you no good if you cannot SEE the test equipment or the things you need to test. So therefore we advise everyone to have a flashlight of one sort or another handy. Whether you choose a traditional handheld flashlight or one that leaves both your hands free to perform your testing, no technician should ever get caught with their pants down… or without a flashlight.
Today we will have a fine selection… of meters for use in all sorts of applications including testing concrete for moisture, testing for the strength and presence of UV light, and testing for the presence and strength of an electromagnetic force. With these tools on your belt, or in your service truck, you’ll have everything you need for the following situations:
* Determine how long ago someone buried a dead body in concrete
* Figure out whether or not light will get through the tarp you wrapped the dead body in and accelerate the decomposition process
* Attempting to prove that ghosts live in your apartment so you have legal grounds to break your lease
All kidding aside, meters come in handy when you have a job to do. If the meters on this blog entry don’t do what you need, check out the other meters on TestProducts.Com.
The title sounds like the introduction to a really bad joke, we know, but some things just kinda’ happen that way. Today we offer a meter for testing relative humidity and temperature, a meter for monitoring wind speed and a bunch of other parameters, and a rapid test for bacteria that you can use to determine whether or not you should swim in a lake, pond, river or other body of water.
Today we will present a way for you to test the intensity of ultra-violet light, detect how much ‘normal’ lighting an area has, blow a smoke stream into a specific area, solder two pieces of metal together w/o having to worry about lead, measure pressure changes, and test for the presence of lead in paint.
Today we have the eXact Micro 7+ Water Test Meter, a digital soil pH meter, a General Electric protimeter, an ultra-violet light detector, a laser distance meter and and an electronic radon gas detector for your testing needs. Enjoy!
