Product Description

We are considered as a prime manufacturer, exporter and supplier of Ozone Monitor. The provided monitor is well-suited to accurately measure the concentration of ozone in the specific samples. The offered monitor is manufactured at our hi-tech production unit using optimum quality components and cutting-edge techniques in conformity with international quality standards. Beside this, provided Ozone Monitor is also checked on defined series of quality tests conducted by our quality controllers to assure its reliable performance.


  • Authentic results

  • Ideal for continuous monitoring

  • Easy to operate

  • On-panel controls 

Polltech’s Ozone monitors are reliable and user-friendly instruments, which are used for continuous measurement of Ozone concentration in ambient air and at work places such as accelerator installations and irradiation facilities.




  • Chemiluminescence Principle
  • Continuous Monitoring
  • Measures True Ozone And Not Oxidants
  • Compact And Portable
  • Digital Display
  • Ultra High Sensitivity For Ambient Air Monitoring With Thermoelectrically
  • Cooled Photo-Multiplier Tube


  Model PEM– OM 1 is a mains-operated instrument, which is used for ozone measurement in ambient air, where ultra high sensitivity of measurement is required. This is achieved by utilizing sophisticated electronics and keeping the photo-multiplier cooled within a narrow temperature range.

 Model PEM–OM 2 B which is a self-contained, battery-operated portable instrument with LCD display and comes with a built-in ethylene cylinder, is used for measurement of ozone concentration at work places.

 Model PEM–OM 2 M is the mains operated version with LED display, which can also be provided with a built-in ethylene cylinder on specific request. 

Principle of Operation


It is a well-known fact that when Ozone reacts with ethylene, the formaldehyde molecules produced thereof are in the electronically excited state. These excited molecules return to their stable ground state by releasing energy in the form of visible light. (The phenomena is known as Chemiluninescence). The intensity of light so emitted is a measure of ozone concentration.

Detailed Technical Specifications

The monitor consists of a reaction chamber–photomultiplier assembly, a sampling system and an electronic unit.  All the systems and components are housed in a sturdy cabinet. The specially designed reaction chamber is made of glass with two inlets one for sampled air and the other for ethylene. It is provided with an outlet for exhausting the reaction products. The photo-multiplier is optically coupled to the reaction chamber.

 The sampling system comprises a suction pump and devices for measuring and controlling the flow of sampled air and ethylene. It also comprises charcoal traps for removing ozone for facilitating zero calibration of the monitor.

 The electronic unit encompasses a precision high voltage supply for the photo-multiplier, signal conditioning and amplifier and other electronics for control, display and recording.
