PORTABLE METHANE ANALYZER MRP-1
|
Purpose
Portable methane analyzer MRP-1 is used for automatic measuring of volume methane concentration in air, digital indication at LCD of measuring meaning, sound and light alarm at the exceeding of fixed thresholds of methane concentration. |
|
The description
The analyzer has the indication of current and full discharge of the accumulator, the indication of disrepair.
The analyzer has the two threshold of alarm action.
The analyzer has light and sound alarm of critical and full discharge of the accumulator.
The analyzer consists of metal enclosure with involved thermocatalytic sensor, accumulator, processor module and LCD.
Power of the analyzer are carried out from the accumulator.
The analyzer is explosion proof and marked "PO Exiasl X". It can be used at explosive areas coal and salt mines.
