Electro Optical Components offers their O2 (Oxygen) sensor that has longer life and is lead free…
Now there are Electrochemical Sensors for monitoring low levels of CO, NO2, O3, SO2, NO or H2S gases. There are also reliable PID sensors for measuring VOCs. The gas sensors are designed for air quality monitoring to measure the low-concentration 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 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,
All the SemeaTech and Senovol sensors are available from Electro Optical Components.
