Detection gas: Hydrogen Cyanide Range: 0100 ppm Resolution: 0.1 ppm Product overview This fixed hydrogen cyanide detector uses original Swiss imported sensors to deliver stable, resolution gas measurement across a 0 to 100 ppm range. Standard threewire 420 mA analogue output and RS485 digital output provide easy integration with common control and monitoring systems. An infrared remote control allows configuration and calibration without opening the unit cover, including alarm point setting, zero calibration, and address modification. Key benefits sensitivity and precision: 0.1 ppm resolution supports early detection and reliable monitoring within the 0100 ppm range. Stable sensing element: original Swiss imported sensors offer consistent performance and longterm signal stability. Easy system integration: standard 420 mA analogue output and RS485 interface connect directly to PLCs, DCS, and control panels. Nonintrusive maintenance and setup: infrared remote control enables alarm threshold changes, zero calibration, and address programming without opening the enclosure, reducing service time and disturbance to the installation. Flexible deployment: threewire connection simplifies wiring for power and analogue output in typical field installations. Functions and performance Gas detected: hydrogen cyanide Measurement range: 0 to 100 ppm Resolution: 0.1 ppm Sensor: original Swiss imported sensor for stable response Outputs: threewire 420 mA analogue output and RS485 digital output as standard Remote operation: infrared remote control supports alarm point setting, zero calibration, and address modification without opening the cover Compatibility Interfaces with industrial control systems that accept 420 mA analogue signals and RS485 communications Suitable for integration with common PLCs, DCS units, and monitoring systems that use standard analogue or RS485 inputs Practical applications Chemical and petrochemical plants: continuous monitoring of hydrogen cyanide in process areas and near storage or handling points Laboratories and research facilities: fixed monitoring where hydrogen cyanide may be present during experiments or sample processing Industrial ventilation and confined spaces: monitoring in areas where HCN release is a risk to process continuity or personnel operations What is included and installation notes Detector with Swiss imported sensor and preconfigured analogue and RS485 outputs Infrared remote control for configuration and calibration without opening the cover Threewire connection for power and 420 mA output For reliable HCN monitoring where accurate measurement, simple integration, and nonintrusive configuration are required, this detector provides precise detection, standard industrial outputs, and remote setup capability.
