3. Multi-sensor design, applied for extreme environments
4. Importing sensor with original package
5. Double-window LED display with 3+2 digits
6. High brightness LED instruction( clearly seen in 10 meters)
7. Output of 4-20mA,Rs485( optional)
8. All stainless steel, 120dB sound with explosion-proof sound&light alarm
Certificates
1.one patent of practical new technique.
2.two patents of appearance technique.
3.fire control type approval of the ministry of public security.
4.National explosion-proof electric inspection.
Characteristics of sensor
1.plug and play
2. High concentrations protection (applies only to catalytic sensor)
3. High precision & wide range hardware VGA (variable gain amplifier) avoids the sensitivity decrease brought only by software amplification.
4. Each probe contains a extra temperature sensor to compensate the impacts to gas sensor by temperature.
5. Artificial intelligence compensation technology makes reading more smooth and stable.
6. Sensor lifetime system from the viewpoint of sensor helps the user know whether the sensor need to replace or not.
7. Double output of current completely satisfy the requirements of Dual-use machine.
