Suitable for a variety of mixed gas concentration detection in various industrial environments and special environments
Standards
GB3836.1-2010 "Explosive environments - Part 1: Equipment - General requirements", GB3836.4-2010 "Explosive environments - Part 4: Equipment protected by intrinsically safe" i "
Steps
1. Turn on the instrument.
2. Set parameters such as custom detection mode (real-time or timing) and storage mode (real-time or timing) through the instrument as needed.
3. Align the instrument sampling port or place it in the environment to be tested, and the built-in air pump will automatically suck the gas for detection.
4. Read the carbon monoxide concentration value in real time on the instrument screen.
5. After the test is completed, the stored historical data can be viewed on the instrument screen.
Notice
* Instrument operating temperature is -30~ 60 ℃, operating humidity ≤ 95% RH (no condensation), Operating Pressure is -30Kpa~ 100Kpa, please use under specified environment conditions.
* The instrument has a built-in 4000mA rechargeable polymer battery, please pay attention to charging in time.
* Instrument Protection Rating is IP65 with Dust Filter, but it is still necessary to avoid use in extremely harsh conditions beyond its protective capacity.
