Designed for critical gas monitoring, the Polytron 8100 EC is Dräger’s leading explosion-proof transmitter for toxic gases and oxygen. It includes a high-precision electrochemical sensor and supports analog and digital communication protocols, including relays, Modbus, and Fieldbus.
• Durable, intelligent and sensitive – the DraegerSensor
• Easy device management via digital communication
• Same design, same operating principle (Polytron 8100 belongs to the Polytron 8000 series)
• Three relays for controlling external equipment
• Safe, robust housing for every application
• Remote sensor option does not require conduit
• More functions through dongles
• Oil refineries/mining/OnShore/Off Shore /Water treatment Plant
• Normal measurment possible with 4-20mA , Hart and optional Relay
• Measuement of Toxic Gases inside the Duct ( Remote installation up to 30 meters Available)
• Hazardous area Application (zone 1,Zone2)
• Contionous monitoring of Oxygen,H2S, Confined Space Installation to monitor
• Remote installation with relay options.
