BH-4S Portable Multi-gas Detector
BH-4S portable multi-gas detector could detect combustible gas, O2, and other two types of toxic gases continuously and simultaneously. It is widely used in areas where explosion-proof is required or toxic gas leaks, like underground channels or the mining industry, so as to protect the worker's life and avoid damage to the relevant equipment.
* 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 contacted with computer via software. Can print the data records, can store data records, can make the data analysis.
