fixed NH3 gas leak alarm

Description:

OC-F08 fixed NH3 gas alarm used the original imported sensor and the ultra low power 32 bit microprocessor, so with the advantages of high precision, good repeatability, stable signal, respond quickly, etc. Possible connected with many controller system, such as PLC, DCS, computer and other, with the function of remote monitor and alarm, data logger and analysis.

oceanus gas detector

Common applications is gas safety inspection and alarm for industrial scene, such as poultry farm, henhouse, refrigeration apparatus, freezing room, etc. where need to detect the Ammonia NH3 gas concentration.



Features:
4-20mA standard analog signal and RS485 digital signal output, 200~1000HZsignal output, relay output, data restore, data logger(optional);
LED screen displaying the gas concentration, gas type, unit, instrument status etc.
Independent air chamber, the sensor is not required to replace the sensor calibration, automatic identification of key parameters of the sensor;
Protection function to prevent high gas concentration attack;

Display the gas concentration in ppm, %LEL, %vol and mg/m3 is selectable;

Infrared remote controller operation;

With the 16bit ADC acquisition chip, designed with four-layer circuit board, so with high anti-interference ability;

With the Ex-proof certificate, the Ex-proof grade is Exd II CT6.
