2. Special inner installed protection gas way, when suddenly power off, it will automatically shut down the gas way to protect the sensor from being exposed in the air;
3. New structure measure room to meet the requirement of replacing sensor quickly;
4. 0-25% manually set measure range, the minimum measure range is 0-10ppm,the maximum measure range is 0-10000ppm;
5. 2 way SPST alarm function;
6. RS232 directional communication port to connect with the computer or other data communication equipment;
7. Isolated 4-20mA DC standard signal output,0-100mV,0-1V or 0-10V analogue output can be choose from, but need to specified when place the order; (please note signal output only 1 kind, please choose one kind based on your applications)

Specially Notice
l The gas inlet pressure should be 35-210KPa before inputting the sample gas into the analyzer,the sample gas flow should be controlled at 1-1.5L/min by the needle valve, the flow should not over 2 L/min,please operate as this notice, or it will damage the sensor, flow meter and pressure sensor;
l The gas outlet should not be blocked, or the safety valve will open automatically, but still if blocked the gas outlet, it maybe damage the sensor;
l Based on the performance of the sensor, work in lower than 1% purity environment is recommended to extend the sensor life;
l To lower the PPm level oxygen purity, the sample gas way, the stainless steel inner polished pipe is recommended, and the sealing state should be very good.
