Principle
The gas detector uses a pump-suction Sampling method, which sucks environment gases into the inside of the instrument through a built-in powerful air pump. After the gas enters a well-designed gas chamber, it comes into contact with an imported electrochemistry or infrared absorbing gas Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed and analyzed at high speed and High Accuracy via a microcontroller (an ultra-low power 32-bit processor using semiconductor nanotechnology) and a 24-bit ADC data collection chip. Finally, the gas concentration value is displayed in real time on the 3.5-inch IPS industrial color screen. The instrument has a temperature compensation function to cope with the impact of environment temperature changes on the measurement and ensure the accuracy of the detection results.
Applications
It is suitable for gas concentration detection in various industrial environments and special environments.

Notice
• Do not use in conditions beyond the working environment temperature (-30~ 60 ℃) or humidity (≤ 95% RH, no condensation).
• Do not use in an environment beyond the working air pressure range (-30~ 100Kpa).
• The instrument has an explosion-proof mark (ExdII CT4), but it still needs to be used in the specified explosion-proof environment and avoid use in places with strong static electricity or strong magnetic field interference.
• The built-in battery is a polymer rechargeable battery, please pay attention to the overcharge protection function and use the matching charger to charge.
• The instrument is equipped with a Dust Filter, make sure the Filter is effective when used in harsh environments and maintain it regularly.
• When calibrating, use standard gas and strictly follow the operating procedures to ensure measurement accuracy.
• Avoid severe impact or drop of the instrument to prevent damage to internal precision components.
• When cleaning the instrument, please wipe it with a soft dry cloth to avoid the use of corrosive chemical solvents.
