These high resolution electrochemical sensors are designed for air quality monitoring to measure the low-concentration of CO, NO₂, O₃, SO₂, NO or H₂S gas with ultra-high resolutions. The design optimizes the sensor sensitivity, accuracy and long-term stability and enables the sensor to detect  variations at parts per billion (ppb) levels. 

The Senovol PID Sensors are designed for the detection of a wide variety of volatile organic compounds (VOCs). In general, any compound with ionization energy (IE) lower than that of the lamp photons can be measured. Based on its proprietary ultraviolet (UV) lamp technology, Senovol PID sensors have the advanced features of high UV outputs, and long lamp life spans,
