OC-FO8 Description:

OC-F08 series online gas detector use the imported sensor and microcontroller technology, so with the advantages of high precision, good repeatability, stable singal, respond quickly, ect. 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.

Common applications is gas safety inspection and alarm for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, metallurgy, mining, fire, environmental protection, etc.

OC-FO8 Features:

4-20mA standard analog signal and RS485 digital signal 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

Digital automatic tracking and compensation of temperature in the whole range to ensure the measurement accuracy.

Software automatic calibration function.

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

Infrared remote controller operation;
