Analyser instrument co manufacturesoffers a new range of infrared gas sensors from edinburgh instruments ltd, uk. These infrared gas sensors are constructed , designed specifically at detector of refrigerant gases. Developed from the guardianplus wall-mounted gas monitors and gascard ii oem sensors, respectively, the guardian fr and chillcard ii instruments are designed to measure a wide range of hfc and hcfc refrigerants [freons]. Chillcard ii sensor is based on the eurocard format and ideally should be incorporated in the client`s own instrumentation. Both models are capable of being mounted up to 30 meters from the sampling point with continuous delivery of sample gas to the sensor being achieved by means of sampling pump and flexible tubing. In addition, there are two models designed to detect ammonia. Some of the technical features of these gas sensors include: the standard measurement range for all instruments is 0-1000 ppm by volume and the range of instruments is available to measure the following gases in air r-125, r-134a, r-123, r-22, r-11, nh3, etc. The guardian fr design can be wall-mounted and is supplied in an ip54 rated enclosure, giving protection against the ingress of particulates and water. Chillcard ii sensor is based on the eurocard format and ideally should be incorporated in the client`s own instrumentation. Both models are capable of being mounted up to 30 meters from the sampling point with continuous delivery of sample gas to the sensor being achieved by means of sampling pump and flexible tubing.
