---------- INDUSTRY ------------ Gas Analyzers and Detectors

AO-4AS portable multi-gas detector could detect combustible gas, O2 and other two types toxic gases continuously and simultaneously.
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.

Detecting gas:

Combustible gas, H2S, CO, O2

*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.
