K-100 portable single gas detector can make continuous detection to combustible and toxic gases. It is suitable for combustible and toxic gas leakage detection in underground pipe or mines, and keeps the workers safe, prevents the facilities from being destroyed.
The detector, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and reproducibility. The detector adopts embedded MCU controller, easy to operate.
The shell adopts special high strength material and anti-smooth rubber, with the characters of water-proof and dust-proof.
1) Advanced MCU control with low power consumption
2) Adjustable low and high alarm level
3) Adjustable calibrating level
4) High concentration protection for combustible gas
5) Self test for the combustible gas sensor
6) Low battery indication
7) Replaceable sensor module
8) Self-adjustment function
9) Visual and audible alarm with vibration
10) STEL and TWA alarming for toxic gases
11) Advanced self-examination and self-renovation function
12) Password management to avoid wrong operation
13) Explosive proof housing


Bosean has been committed to the development of the gas detection industry with strong economic strength and strong technical strength , specializing in the research, development, manufacturing and sales of gas detectors.We have continuously developed new products with international advanced technology.
