Original imported high performance sensor, high measurement accuracy, good stability and repeatability, long service life.

Have the history record function, can record the alarm information.

Embedded 32-bit ultra-low power processor, equipped with a unique signal processing algorithm, fast response speed.

Multi-stage pretreatment system is suitable for the complex environment of high temperature and high water vapor.

It can show the real-time concentration of the gas, and show the gas change process in detail.

With 2 RS-485 digital channel; one is connected to the gas detection module and the other is connected to the cloud;

Adopt long life pump, imported corrosion resistant sampling pump has long life, can work continuously for more than 10000h.

Excellent front-end pretreatment system, which can dry and filter the detected gas. Ensure that the gas detection is more accurate, more stable in use, and effectively prolong the life of the sensor.

All gas passages are made of corrosion-resistant materials to avoid adverse effects caused by corrosive gas.

All interfaces use excellent air tightness elements to ensure the effectiveness of gas detection.

Easy installation, maintenance, and disassembly.
