The Model 202 Ozone Monitor™ is designed to enable accurate and precise measurements of ozone ranging from low ppb (precision of ~1.5 ppb) up to 250,000 ppb (0-250 ppm) based on the well-established technique of absorption of UV light at 254 nm.  Flash card memory and a quiet, long-life internal air pump are now provided standard on the Model 202 Ozone Monitor.  The Model 202 ...

For industrial ozone applications, 2B Tech offers the Model 106-L, 106-M, 106-MH and 106-H Ozone Monitors, where L, M, MH and H refer to Low (0-100 ppm), Medium (0-1,000 ppm), Medium-High (0-10,000 ppm) and High (0-20 wt%) ozone concentrations, respectively. These instruments have different optical path lengths in order to accommodate an extremely wide range of ozone concentrations, spanning mo ...

The Model 306 Ozone Calibration Source™ is a portable source of ozone that allows you to calibrate any ozone monitor - not just those manufactured by 2B Tech. The instrument scrubs ozone from ambient air and produces any mixing ratio of ozone in the range 30 to 1,000 ppbv. The desired ozone concentration is chosen from the easy-to-use menu using a rotary select switch, or can be controlled r ...

The Model 205 Dual Beam Ozone Monitor makes use of two detection cells to improve precision, baseline stability, and response time. In the Dual Beam instrument, UV light intensity measurements Io (ozone-scrubbed air) and I(unscrubbed air) are made simultaneously. Combined with other improvements, this made it possible to reduce the time between ozone measurements to 2 seconds, makin ...

The new Model 211 Scrubberless Ozone Monitor uses the proven ultraviolet (UV) absorption method in combination with our patented (US Patent No. 8,395,776 B2) gas-phase scrubber technology to measure ozone virtually free of interferences. The instrument is ideally suited for measurements of ozone in heavily polluted air where interference is likely from particulates, mercury, or VOCs. The Model ...

The Model 405 nm NOx Monitor ("nm" for "nanometer" and for "NOx Monitor") is designed for the direct measurement of atmospheric nitrogen dioxide (NO2), nitric oxide (NO) and total reactive oxides of nitrogen (NOx = NO + NO2) in the concentration range 0-10,000 ppb (0-10 ppm) for NO2 and 0-2,000 ppb (0-2 ppm) for NO with high precision and accu ...

2B Tech has taken the next step in miniaturization of UV-based ozone monitors by developing the Personal Ozone Monitor or "POM". The basic POM unit has dimensions of 4 x 3 x 1.5 inches and weighs only 0.8 lb / 1.0 lb without/with battery (360g / 450g ). It has a built in GPS so that ozone measurements may be logged continuously along with geographic location. By folding the optical path ...
