          FST-EO series of ethylene oxide gas detector is suitable for continuous on-line detection of ethylene oxide concentration in various industrial environment and special environment. The instrument adopts imported electrochemical sensors and micro controller technology, which has the advantages of stable signal, high precision and good repeatability, and the explosion proof connection mode is suitable for various dangerous places. The instrument is compatible with control systems such as control alarm, PLC, DCS and so on. It is widely used in the fields of petrochemical, industrial production, flue gas exhaust environment monitoring, sewage treatment, bio pharmaceutical, home environmental protection, school laboratory and so on. The ethylene oxide detector can be customized for different ranges and accuracy. It has two series of sound and light alarm and silent light alarm.
          Technical parameters: detection gas: ethylene oxide (C2H4O) detection principle: electrochemical sensor principle
          Measurement range: 0-20ppm, 0-100ppm, 0-500ppm resolution: 0.1ppm, 1ppm
          Accuracy: less than or equal to 5% (actual concentration, higher precision depends on specific sensor).
          ? repeatability: < < + 3%. Zero drift: less than + 3% (F.S/). Response time: less than 30 seconds (T90). Recovery time: less than 20 seconds / output signal: users can be determined according to actual requirements.
