Miniature Ozone Monitor
The 2Btech monitor is similar to the Thermo Fisher but operates on battery power and is fully portable. The performance specification is similar but due to its smaller size and weight it can be applied to many different applications.

The Model 202 Ozone Monitor, is designed to enable accurate and precise (±1.5 ppb) measurements of ozone ranging from a few ppb to 100,000 ppb (0-100 ppm) based on the well established technique of UV absorbance at 254 nm. The Ozone Monitor, is light weight (2.1 kg.) and has a power consumption of only 4 watts.
The Model 202 Ozone Monitor can be used in almost any application where much larger ozone monitors have been used in the past and in many environments where measurements using traditional ozone monitors are impossible. The U.S. Environmental Protection Agency (EPA) has assigned the method number "901-O3 Model 202" to the Model 202 Ozone Monitor and includes the National Forest Service Network, which makes use of the the Model 202 in their database. EPA approval as a Federal Equivalent Method is pending.
Model 205 Dual Beam
The Model 205 Dual Beam Ozone Monitor was designed for even higher precision and faster response time than our popular Model 202. Data may be output as frequently as every 2 s, making it ideal for vertical profiling using balloons or aircraft measurements where high temporal resolution is required. For a given averaging time, the Model 205 has a higher precision (better than 1 ppb for 10 s averaging) and a more stable baseline than the Model 202. The Model 205 has all of the features of the Model 202 single beam instrument, including a real time clock; averaging times of 10 s, 1 min, 5 min and 1 h; an internal data logger; serial and analog data outputs; and a backup air pump to protect against data loss in the field.
Model 106 for Industrial Ozone Applications
For industrial ozone applications, 2B Tech recently introduced the Model 106-L, 106-M and 106-H Ozone Monitors, where L, M and H refer to Low (0-10 ppm), Medium (0-1000 ppm) and High (0-20 wt%) ozone concentrations, respectively. These instruments have different optical path lengths in order to accomodate this extremely wide range of ozone concentations, spanning more than eight orders of magnitude. Additionally, the Model 106-H was designed with a flow through path that can be pressurized for in-line measurements with ozone generators.
Model OEM-106
For OEM applications where users want to integrate their ozone monitor into a complex system such as an air pollution measurement package, we offer an "Ozone Monitor on a Board" solution. The entire ozone monitor is mounted on a single printed cricuit board. The liquid crystal display and power switch may be removed and mounted outside the package if desired. The OEM board may be purchased with one of three different optical benches to optimize measurements in three different concentration ranges as follows:
OEM-106-L 0-10 ppm with 0.001 ppm (1 ppb) resolution
OEM-106-M 0-1,000 ppm with 0.01 ppm resolution
OEM-106-H 0-20% by weight with 0.01% resolution
Model 306
The Model 306 Ozone Calibration Source is a highly portable ozone transfer standard that may used to calibrate any ozone monitor or sensor. Ozone is generated at any chosen concentration in the range 0-1000 ppb in ozone-scrubbed ambient air at a volumetric flow rate of 3 L/min. No external air source is requried. The instrument may be programmed to output a series of up to 10 ozone concentration steps with a chosen time interal. The Ozone Calibration Source is provided with a NIST-traceable calibration, and the menu allows the user to calibrate the output to their own reference instrument. This Ozone Cal Source is particularly useful for calibrating networks of ozone monitors in the field.
