Oxy-comm zirconia oxygen analyser description The oxy-comm zirconia oxygen analyser is designed for controlled atmosphere applications such as refrigerated transportation containers and fire prevention. The oxy-comm zirconia oxygen analyser combines a high accuracy zirconium dioxide oxygen sensor with a networkable, fault tolerant rs485 interface. The oxygen analyser is mounted under a stainless steel hood to protect it from the environment. The ip65 waterproof die-cast aluminium housing accommodates the electronics and has a 4-pole m12 connector to allow multiple devices to be interconnected. The oxygen sensor inside oxy-comm uses a unique closed loop measurement system. While oxy-comm continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures. Due to the innovative design, the oxy-comm zirconia oxygen analyser does not require a reference gas. Low drift means these products do not require frequent calibration but when they do, it is an extremely simple process which can be performed in fresh air which means there is no need for expensive calibration gases. The oxy-comm zirconia oxygen analyser has an 8 to 15vdc supply voltage range with reverse polarity and transient overvoltage protection. The oxygen analyser is barometric pressure compensated and can be calibrated in fresh air (20.7% o2) or to any other known o2 concentration.
