Long lifeDescription
This product is a UV ionization sensor (PID), which is one of the most widely used gas detection technologies. It can detect most volatile organic compounds (VOC) gases. It has unique advantages such as fast response, high sensitivity, large range, and small size. It is widely used in industrial safety, leak detection, environmental monitoring, emergency response, clean workshops and other fields.
