The K800 series fixed gas detector, with 2, 3 or 4 wires connection, 4-20 mA RS485 Modbus output,
provides continuous detection and monitoring of gases for a wide
range of industrial environments. The fixed detector with in-built
alarms and fault relays is suitable for safety protection of
personnel and plant from flammable, toxic and oxygen gases.
>>>Key Features
- Digital and analogue outputs
- LED status indicator light for alarm conditions
- The relay can trigger alarms or process control system
- Three models available for measuring toxic gases, VOCs, or
combustible gases
- Explosion-proof case
- CERTIFICATIONS: UL, CE, CMC, Ex, MA (SAFETY CERTIFICATE OF APPROVAL
FOR COAL MINING PRODUCTS IN CHINA).
