Chinese Professional Portable Carbon Monoxide Detector - JHB4 Methane CH4 detector – Topsky Detail:

Qualifications: Coal Mine Safety Certificate
Explosion-proof Certificate
Inspection Certification
Model : JHB4

Applications:
Infrared Combustible Gas Detector is an intrinsically safe and explosion-proof instrument and is designed to deter Combustible Gas concentration in ambient air continuously and rapidly.
It adopts NDIR infrared technology with high accuracy and fast response. The measuring range of Combustible (CH4) gas is 0-5.0% or 0-100%vol.
Despite its compact size, the Infrared Combustible Gas Detector includes features usually found only in larger multi-gas monitors including a large, OLED display, internal audible/visual alarms and simple push-button operation.
The monitor continuously displays ambient combustible gas readings and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. Infrared Combustible Gas Detector also has a peak/hold feature to show the highest reading during a shift and includes a special flip-cap calibration adapter for quick and simple calibration. It is covered by a two-year warranty from the date of manufacture.
It is used at the underground coal mine and mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the combustible gas.
