●Fast and efficient gas detection function

① It can be used in 24 hours continuous online monitoring of single field gas concentration and the types for detection are more than 500 types.

●Diversified communication methods

① It is possible for the real-time monitoring via the wired or remote wireless transmission, and network transmission.

② Three-wire system 4 ~ 20mA standard signal and standard bus RS485 (modbus-RTU) simultaneous output.

③ It is compatible with secondary instrument, data acquisition module, PLC, DCS system, and it is possible to drive the related equipment.

●Powerful and convenient humanized function

① Data recovery function; in case of mis-operation, it is possible

to select partial or full recovery.

② Multiple alarm modes, and multi-directional and threedimensional indication alarm states, includes: 2 sets of relay switch output, sound & light alarm (optional configuration).Alarm types include: concentration alarm, and failure alarm.

③ Mis-operation recognition function: automatic recognition and prevention of the concentration calibration mis-operation, which is possible to avoid the poor performance that may becaused by human factors.

④ Zero-point automatic tracking; long-term use will not be affected by the zero drift.

⑤ Multi-level calibration for target points, can ensure the linearity and accuracy of the measurements.

⑥ Broad operating temperatures: -40～+70℃, and temperature compensation is supported.

⑦ Intrinsically safe circuit design, explosion-proof, with Level II lightning protection, and anti-static capabilities. Meet the national standard, and it is resistant to the high-intensity pulse surge current. With the function of preventing the reverse connection. It is compliant with EMI, and EMC standards.
