Introduction:

Portable multi-gas detector could detect four gases at once time. It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers’life and avoid damage on the relevant equipments. 

Features:

* Natural diffusion sampling method and high-sensitivity sensor, with high sensitivity and repeatability.

* 32-bit built-in MCU, high reliability and self-adaptation ability.

* Full functions, easy operation.

* CSTN colorful LCD, more intuitionistic, abundant and clear indication.

* Compact design, easy carrying.

* High strength engineering plastics and compound anti-slippery rubber; high strength, water-proof, dust-proof and explosion-proof. 

*500pcs data records, can be contact with computer via software. Can print the data records, can store data records, can make the data analysis.
