Instruments that measure air velocity and air/surface temperatures are one of the most important tools an HVAC tech will have in his tool box. With these meters seeing everyday use, it is imperative that you understand the limitations of certain instruments and select the correct one. Having the right tool will help grow your business and will pay for itself and then some. With so many options out there, I wanted to highlight a few models from Extech and discuss what sets them apart.

Extech Moisture Meters MO210/MO220/MO257/MO750 provide a wealth of moisture inspection options depending on your application. I will begin with the Extech MO210, which is a pocket size moisture detector.

Sometimes you just need a small camera on a stick to get a better view of what you are doing. That is why Extech has created the BR200 and the BR250 Wireless Video Borescopes. Both of these borescopes feature a camera that has 712 x 486 (NTSC) pixels as well as a 3.5” detachable display. Having the display be detachable is a nice feature that allows you to use this in tight spaces that may not be wide enough to fit the screen through. The main difference between these two borescopes is the camera and probes.

Hello testing enthusiasts. Today’s post is going to cover some fairly simple but reliable little testers, the Extech SD500 and Extech SD700. These meters both offer quick and accurate temperature and humidity readings in controlled environments like cleanrooms, manufacturing plants, warehouses, and so on and so forth. The SD700 adds the ability to take barometric pressure readings and both meters can simultaneously display all the parameters that they respectively measure.

Everybody loves a sale! However, the new pricing for Extech Oscilloscopes goes way beyond your normal 10 to 20% off kind of thing. We’re talking darn near half price for the same great units that used to cost a fortune. The Extech MS6060, Extech MS6100, Extech MS6200 are all drastically reduced in price saving the customer $600-$900 just off the list price.

      Today I will be discussing the Extech CT70 AC Circuit Load and Outlet Tester. This circuit load tester may be small, but it packs a big punch. The first thing you notice about this load and outlet tester is the digital display. This innovation is oddly late to the party but makes life so much easier. When using the CT70 as an outlet tester the display will shine Blue for Pass and Red if there is a problem. The outlet functions that it handles are as follows,
