Gas Dog gas detectors units can detect a wide range of gases including Ammonia, CO2, fluorinated refrigerants, and Propane. Gas Dog gas detectors come with various sensor technologies to match the specific refrigerant, application, and safety requirements of the refrigeration system including electrochemical, semiconductor, Pellistor, and infrared sensors. Gas Dog gas detectors measure the level of different gases within the air, and are used to prevent anyone from being exposed to toxic gases that could poison or kill. Gas Dog gas detectors can be portable or stationary, and can detect combustible gases, oxygen, and toxic gases. Common sensor types used in Gas Dog gas detectors include electrochemical sensors, catalytic sensors, photoionisation sensors, infrared sensors, galvanic sensors, and semiconductor sensors. Gas Dog gas detector is used to monitor the gas concentration in your warehouse and workplace. When the concentration exceeds the preset alarm value, it will send out an audible and visual alarm signal to remind users to take safety measures in time.
