OC‑F08 Fixed Gas Detection System is built around OC‑F08 fixed gas detector, equipped with imported sensor and 32‑bit microprocessor. It achieves high‑precision real‑time gas concentration measurement, fast response to gas leakage risk. Supporting 4‑20mA, RS485 and relay output, it connects with PLC/DCS system, realizes remote monitoring, alarm trigger and data logging for full‑time industrial site safety protection.

Description
The OC-F08 fixed gas detection system adopts original imported sensors and ultra-low power 32-bit microprocessors, which have the advantages of high accuracy, good repeatability, stable signal, and fast response.

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.
