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.

Borescopes, borescopes, borescopes!! So many choices. Where to begin? This handy little post will hopefully help you navigate the murky waters of video inspection with a look at the line-up of borescopes offered by General Tools.
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.
Getting the most out of each piece
of testing equipment is becoming the industry norm. Gone are the days of single use testing equipment. If my tester doesn’t take accurate measurements and heat up my lunch, I will find one that will. Byte Brothers understands this principle and packs many features into its equipment. The Byte Brothers CPK1000IL CAT5/6 Cable Certifier is a kit that includes two fantastic multifunction meters.
The T3 Innovation AC120 Arc Chaser is 
a serious piece of technology. This unit is equipped with Spread Spectrum Time Domain Reflectometry (SSTDR) which gives the AC120 an accuracy within 1% to a fault. The T3 AC120 Arc Chaser monitors intermittent opens, shorts and faults and can work on both energized and unenergized cables.
Finding the right Cable Certifier can be quite time intensive.
There are many options out there and it can get confusing. Today I will be talking about the Ideal Industries 33-993 LanTEK II series Cable Certifier. This particular model is the 1 GHz bandwidth version which is the top end of their offerings (the other models being 350 and 500 MHz respectively).
With the weather beginning to change,
the “Combustion Season” is again upon us. It’s time to analyze your old equipment and see what needs to be replaced. A new CD100A Combustible Gas Detector by UEi would be a great addition or replacement to your existing equipment. This detector is lightweight and can be used with one hand. There is an option for a headphone jack as well which can help if you are in a congested area or working in a noisy environment.
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.
The UEi C155 Combustion Analyzer
is a no nonsense analyzer that gets the job done. This analyzer can measure temperature (20-2400 F), CO2 (0-20%), CO (0-2,000ppm). The C155 uses a CO2 sensor and the CO measurements to calculate the O2 present which increases the shelf life of the sensors.
Today I will be going over the TSI 9515 VelociCalc Air Velocity Meter. 
This meter is an excellent entry level air velocity meter for the professional HVAC technician. The TSI 9515 separates itself from the plethora of air velocity meters in this price range by having a range of 0 to 4,000 ft/min (0 to 20 m/s) and an accuracy of 5%.
