RAE Systems QRAE II Calibration

The QRAE II is a popular portable 4 gas detector, so we've added to our list of videoes for you to enjoy.
Meantime, I've been finishing up the work on my stable calibration gas coating andtesting an Infrared Meter suitable for HAZMAT situations for distances of up to 300 feet. Sor far the results look great! I'll be back with more on this and another calibration video after the next round of calibration gas testing is done.
