Description
Overview
GAOTek VOC handheld reliable quality gas analyzers with the most advanced nanometer semiconductor technology, ultra-low power 32 bit microprocessor,24 bit ADC data acquisition chip, outstanding accuracy. temperature and humidity detection, user can detect temperature and humidity value on the scene or the temperature and humidity value inside the pipe. With high-power pump allow device working under tiny negative pressure condition, the reasonable gas chamber design ensures that the sensor is not affected by the pressure.
