Overview
Enviro Test Construct ammonia gas analyzer is possible for the real-time monitoring via the wired or remote wireless transmission, and network transmission; three-wire system 4 to 20 mA standard signal and standard bus RS485 (Modbus-RTU) simultaneous output; it is compatible with secondary instrument, data acquisition module, PLC, DCS system, and it is possible to drive the related equipment. Data recovery function; in case of mis-operation, it is possible to select partial or full recovery. Multiple alarm modes, and multi-directional and three-dimensional indication alarm states. It includes 2 sets of relay switch output, sound and light alarm (optional configuration). Alarm types include concentration alarm, and failure alarm.
