Portable Gas Detector/ Single portable O2 oxygen Detector
Applications:
Portable O2 detector is an intrinsically safe and explosion-proof instrument and is designed to deter O2.
Portable O2 detector is a low-cost, maintenance-free single gas monitor designed to protect personnel from dangerous O2 gas exposure in the most extreme conditions. Despite its compact size, the Portable O2 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. Portable O2 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. Portable O2 detector 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.
