Volatile Organic Compound Sensors (VOCs)

The SensorsX SX-GVOCPSA Series is a compact photoionization detector (PID) VOC gas sensor designed for high-sensitivity volatile organic compound (VOC) detection. It uses a 10.6 eV UV lamp to ionize VOC molecules and provides detection from ppb levels to high-ppm concentrations with fast response, high stability, and long operating life. It is suitable for environmental VOC monitoring, industrial safety, and portable VOC detection instruments.
