AO-4AS 4 in 1 Multi-Gas Detector
AO-4AS portable multiple gas detector could detect combustible gas O2 and other two types toxic gases continuously and simultaneously.
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.
