Description
Overview
GAOTek fixed hydrogen cyanide gas detector with LED display transforms the gas density in the operating site into standard electric current signal (4 mA to 20 mA), RS 485, Relay. It has excellent performance, stable operation, and easy maintenance. Since the detector also can detect various gases, it meets various requirements in the operation site it has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine water procession etc.
Features
- Standard 4 mA to 20 mA current output, or RS 485 output compatible
- LED site display
- Standard three buttons so an individual can operate the detector on-site
- Automatic identify and display the sensor failures, and output the corresponding
- The key operation needs to input a password to prevent the wrong operation
- Simple calibration function reducing measuring error
- Two levels of light alarm, relay output (connected with audible and visual alarm
