High Sensitivity VOC Gas Sensor

OEM gas sensor with state of the art sensing technology

Designed for OEMs, the high sensitivity gas sensor – MiniPID 2 is the latest in the range of PID sensors from ION Science for sub PPB level detection.

The ground-breaking high sensitivity gas sensor is 15 times more sensitive than the existing PPB gas sensor and capable of detecting trace levels of volatile organic compounds (VOCs) over a long period of time making it ideal for indoor air quality monitoring applications.

Delivering a dependable response to thousands of VOCs across many diverse applications, the high sensitivity VOC sensor is a simple plug and play sensor providing a wide detection range of 0.5 ppb up to 3 parts per million (ppm). ION Science’s high sensitivity gas sensor also features a re-designed, pneumatically sealed electrode stack for high sensitivity and a wide detection range.

An innovative self-diagnostic feature indicates whether the electrode stack is contaminated or if the sensor is not operating correctly. The high sensitivity VOC sensor incorporates ION Science’s long-life lamp that offers 10,000 hours continuous operation. Together with exceptional brightness and improved stability, this facilitates reliable detection of less volatile and less readily sensed compounds, over an extended period of time.
