Advantage: Compact, easy installation Long life zirconia sensor Five to ten years expected operational life Sensor will not dry out or freeze Low maintenance Low cost Caution: Never expose the Transmitter to flammable gases. Please keep the sensor in good air ventilation. Please keep the sampling flow at calibration rate. Please keep the power at right voltage. Description: The OT series transmitter is a cost effective solution in a small package for oxygen measurement and control applications. It is compact, cheap and easy installation and designed to provide the trained operator with useful information relating to the concentration of oxygen in non-flammable gases and non-hazardous area. Its microprocessor based main board can offer accuray output for trace or high levels oxygen concentration. It is ideally suited for installed in your equipments like Solder Reflow Machine and control boxes of semiconductor furnaces, glass manufacture, inert atmosphere chambers, and gas generators.
