Revolutionary mercury-free gas measurement module

Ozone (O3) is an effective disinfectant for surfaces, water, and air due to its strong oxidizing properties, which enable it to neutralise viruses, bacteria, fungi, and other pathogens. 

Its presence is detectable by its distinctive odour, even at very low concentrations (below 1 ppm), with the odour threshold around 0.02 ml/m³ (0.02 ppm). 

As a result, ozone measuring devices need to be highly sensitive, capable of measuring even trace amounts in the ppb range. 

Traditionally, these sensors have relied on toxic mercury vapour lamps as a radiation source. However, Wi.Tec Sensorik GmbH in Germany has pioneered a mercury-free ozone sensor using UV LEDs, delivering high-precision measurements without the environmental hazards of mercury.

The ULTRA.sens® AK250 sensor offers a measurement range of 0-1000 ppb of O3, with a detection limit of <5ppb. 

It features automatic zeroing (AZF Auto Zero Function), ensuring near-zero drift and long-term stability. 

With low power consumption ((<1W at 24V DC), the module is also well-suited for integration into portable devices.
