What is it For
Portable ozone monitors are widely recognized and used for their proprietary best-in-class ozone technology that delivers highly selective ozone measurement at low concentrations (down to 1 ppb). They can be used both for indoor and outdoor air monitoring. They are ideal for:

• Process monitoring and control
• Detecting ozone leaks
• Ensuring workplace health and safety
• Mapping outdoor ambient ground-level ozone
• As an educational tool for students to understand outdoor ozone pollution
• Personal monitoring

How it works

Sensors are housed within an interchangeable ‘sensor head’ that attaches to the monitor base. Each sensor head contains a single gas or particle sensor. Swapping sensor heads takes seconds, can be done in the field, and no configuration or re-calibration is required.

Active sampling is a key design feature. Each sensor head contains a fan that works continuously or periodically (depending on the sensor type) to draw sample air to the sensor. Once sampled the air is exhausted from the opposite side of the sensor head. The monitor base itself is a flexible electronic platform designed to fit comfortably in the hand. The monitor base comes in different models with different features. The full-featured Series 500 has onboard data-logging, and digital and analogue outputs, and comes bundled with free desktop software. It can also be zero and span calibrated in the field allowing for maximum traceability.

What does it measure?
Our portable ozone monitors can measure up to 5 different ozone ranges, depending on your requirements. All our ozone sensors are made by using unique Gas Sensitive Semiconductor (GSS) technology. GSS technology allows ppb-level detection of ozone with high accuracy and stability. Our ozone sensors are best-in-class for measuring ozone at low concentrations, particularly in the 1-100 ppb range.
