Industrial Ozone Monitors
Model UV-106-W Aqueous Ozone Monitor
|
The Model UV-106-W Aqueous Ozone Monitor™ uses our patented MicroSparge™ technology to measure dissolved ozone in water with high precision and accuracy. Unlike most dissolved ozone sensors, the instrument does not make use of a membrane that will foul over time. Instead, dissolved ozone is measured by nearly complete sparging (bubbling) of ~2 mL of water with ozone-scrubbed ambient air and integrating the gas-phase concentration of ozone stripped from solution. A small correction, based on the temporal profile of ozone removed from solution, is made to account for any ozone remaining in solution. Because ozone is measured in the gas phase, interferences from particles and dissolved inorganic and organic compounds are removed, making the instrument applicable to both ultra pure water and “dirty” water, such as drinking water, which can contain a wide variety of dissolved inorganic and organic impurities and suspended particles.

Model 106-L Ozone Monitor for Ambient Ozone Measurements
|
The Model 106-L is designed for ambient ozone monitoring for health and safety monitoring in an industrial ozone setting based on the accurate method of UV absorbance. A simple design with all components mounted to a single printed circuit board and a long-life pump make the instrument highly reliable and robust. Ozone is measured in the range 0-100 ppm (0-100,000 ppb) with a resolution of 0.1 ppb. Precision and accuracy for this low-concentration ozone monitor are ±1.5 ppb or 2% of reading. The Model 106-L has been designated by the US EPA as a Federal Equivalent Method (FEM). Configurations for multi-channel air sampling are available as an option. The instrument can be purchased in an Industrial enclosure.

Model 106-M Ozone Monitor for Off-Gas Measurements
|
The Model 106-M provides ozone measurements by UV absorbance in the 0-1,000 ppm concentration range with a resolution of 0.01 ppm (10 ppb). This medium-range ozone monitor can be used for ambient monitoring as well as off gassing from ozone-treated water. Configurations for multi-channel air sampling are available as an option. The instrument can be purchased in an Industrial enclosure. More Info Request Quote |

Model 106-MH for Off-Gas Measurements and Ozone Generator Output
|
The Model 106-MH provides ozone measurements by UV absorbance in the 0-10,000 ppm (0-1% vol) concentration range with a resolution of 0.01 ppm (10 ppb). This medium-range ozone monitor can be used for measuring ozone offgas as well as the output for lower concentration ozone generators. Configurations for multi-channel air sampling are available as an option. The instrument can be purchased in an Industrial enclosure. More Info Request Quote |

Model 106-H for Output of High Concentration Ozone Generators
|
The Model 106-H is a high concentration ozone monitor designed for measuring and controlling output concentration of a high concentration ozone generator. Ozone is measured in the range 0-20 wt% with a precision of 0.01 wt% or 2% of reading by the method of UV absorbance. The instrument is available in a standard case or in an Industrial enclosure.

Model 106 Series OEM "Ozone Monitor on a Board"
|
For OEM applications where users want to integrate their ozone monitor into a complex system such as an ozone treatment package, we offer an "Ozone Monitor on a Board™" solution. The entire ozone monitor is mounted on a single printed circuit 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 four different optical benches to optimize measurements in four different concentration ranges as follows:
OEM-106-L 0-100 ppm with 0.0001 ppm (0.1 ppb) resolution OEM-106-M 0-1,000 ppm with 0.01 ppm resolution OEM-106-MH 0-10,000 (1 % vol) with 0.1 ppm resolution OEM-106-H 0-20% by weight with 0.01% resolution More Info Request Quote |
Personal Ozone Monitor (POM)
|
2B Tech has taken the next step in miniaturization of UV-based ozone monitors by developing the Personal Ozone Monitor or "POM". The POM has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 g). It has a built in GPS so that ozone measurements may be logged continuously along with geographic location. It does NOT use a solid-state or electrochemical sensor, both of which are prone to interferences and baseline drift. Like all of our ozone instruments, the measurement is based on UV absorbance. By folding the optical path in the shape of a "U", it was possible to achieve the same path length in the POM as in the Models 202, 205 and 106-L and thus have similar precision and accuracy (~2 ppb). The POM is ideal for personal ozone exposure studies and health and safety monitoring in workplaces where ozone is produced. The US EPA has designated the POM as a Federal Equivalent Method (FEM).

Model 306 Ozone Calibration Source
|
The Model 306 Ozone Calibration Source is a highly portable ozone transfer standard that may be 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 required. The instrument may be programmed to output a series of up to 10 ozone concentration steps with a chosen time interval. It also has a scheduler function that permits the user to schedule an autocalibration once daily. 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.

The Model 714 NO2/NO/O3 Calibration Source™ combines our Model 408 Nitric Oxide Calibration Source™ with our Model 306 Ozone Calibration Source™ to provide a highly portable transfer standard for three pollutant gases without the need for a compressed gas cylinder of nitric oxide. Calibrated concentrations of O3 are produced by photolysis of oxygen, and calibrated concentrations of NO are produced by photolysis of nitrous oxide. In addition, calibrated concentrations of NO2 are produced by gas-phase titration of NO with O3. Calibrations sequences can be programmed in internal memory via a user-friendly touch screen interface, and the instrument can be operated remotely via a Modbus TCP/IP interface and Ethernet connection to a computer.
