ACD Ozone O3 calibration gas

GENie O3 Module (Variable Flow & Output)

SKU: 750-0202-02

The GENie O3 portable calibration gas standard is small and lightweight for calibrating the most difficult to reach Ozone sensors. The GENie O3 will calibrate nearly any Ozone gas sensor or detection system on the market by utilizing its internal mass flow sensor and ultraviolet light source to provide accurate levels of Ozone gas to the end-user. Ozone gas cannot be stored in cylinders and must be generated on-site, therefore, there are no calibration gas cylinders of ozone available on the market. 


The GENie O3 comes with a NIST certificate of calibration to +/- 10 %, providing exceptional accuracy, as well as high precision. The unparalleled long life source in the instrument has an expected life of up to five hundred hours of use, allowing for extremely low-cost calibrations over the life of the source.
