The gas detection instruments are available in portable, wall mounting, panel mounting version with latest user-friendly micro-controller technology with long life electrochemical sensors. The system accepts input 4-20 mA/3-wire from toxic gas transmitter. The range, resolution, alarm set point, alarm control action are programmable by users. The instrument has very high accuracy of 0.25% with software linearization. It allows easy on-line field calibration by user from front keys. It is supported with programmable latch and non-latch facility for relays and LED indication. It has two independent set points individual with relay output, 1 fault relay for fail safe operation and all the three relays have 1 NO/CNC contact rated 230 V/5 A. It also has non-isolated 4 to 20 mA retransmission output, available for PLC, DCS and any chart recorders. It is provided with an optional RS-232/RS-485 serial port with Modbus RTU protocol for online PC based data monitoring. It is very useful for ambient monitoring, pulp and paper plants, stack monitoring, chemicals and petrochemical, refineries, acid alkalise and dyes manufacturing plants, chemicals processing plants, sewage plants, chemical storage area, offshore drilling and processing platforms, fertilizer plants, furnaces, power and industrial plants and compressor stations.
