Industrial Oxygen Detector / Oxygen Detector / Oxygen Analyzer / On-line Oxygen Detector Model: HAD-O21
I. Product description HAD-O21 industrial oxygen detector is especially suitable for the continuous on-line detection of oxygen concentration in high-purity oxygen, trace oxygen, industrial environment, flue gas exhaust and other special environments. The instrument adopts imported electrochemical industrial oxygen sensor and micro The controller technology has the advantages of stable signal, high accuracy and good repeatability. The explosion-proof wiring method is applicable to all kinds of dangerous places. The instrument is compatible with various control alarms, PLC, DCS and other control systems, and can realize remote monitoring, remote control, remote alarm, computer data storage, analysis and other functions.
