◼︎ Fast and efficient gas detection function

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

It is possible for the real-time monitoring via the wired or remote wireless transmission, and network transmission.
Three-wire system 4 ~ 20mA 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.

◼︎ Powerful and convenient humanized function

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, includes: 2 sets of relay switch output, sound & light alarm (optional configuration).Alarm types include: concentration alarm, and failure alarm.
Mis-operation recognition function: automatic recognition and prevention of the concentration calibration mis-operation, which is possible to avoid the poor performance that may be caused by human factors.
Zero-point automatic tracking; long-term use will not be affected by the zero drift.
Multi-level calibration for target points, can ensure the linearity and accuracy of the measurements.
Broad operating temperatures: -40~+70℃, and temperature compensation is supported.
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.

◼︎ ◼︎ ◼︎ ◼︎ Optional Items ◼︎ ◼︎ ◼︎ ◼︎
◼︎ Wireless transmission

It is possible to transfer data wirelessly to the cell phone, remote monitoring center, monitoring computers and other monitoring equipment, which will utilize the upper-level host to realize the functions of data analysis, storage, printing or the like on the computer.

◼︎ Pretreatment system
