Overview
The GAOPIN NGP40-M400 portable multi-function 4-in-1 Gas detector is a professional equipment for simultaneous rapid detection of carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2) and combustible gas concentrations, and measurement of environment temperature and humidity. The instrument uses a 2.31-inch high definition color screen real-time display, built-in high-performance Sensor, with sound and light vibration alarm function, suitable for gas concentration detection in pipelines, confined spaces, atmospheric environments, and high concentration single gas purity analysis with nitrogen or oxygen background. It can detect more than 500 gas types.

Principle
The detector uses a gas Sensor of a good brand in the industry. For combustible Gas detection, the principle of catalytic combustion is used, and for CO, H2S, O2 and other gases, the principle of electrochemistry is used. The instrument sucks the gas to be measured through the built-in sampling pump, and the gas passes through the integrated water vapor and dust Filter to reach the corresponding Sensor. The Sensor converts the gas concentration into an electrical signal, which is processed by professional circuit design and mature kernel algorithms. Finally, real-time concentration values, Linear dispersion and other information are displayed on the display screen, and sound and light vibration alarms are triggered when the concentration exceeds the set limit.
Applications
Pipeline Gas detection, confined space operation, atmospheric environment monitoring, gas leakage investigation, high concentration single gas purity analysis (background gas is nitrogen or oxygen), industrial safety inspection, environmental protection monitoring
Steps
1. Make sure the instrument has sufficient power before turning it on.
2. Press the power button for a long time to turn it on, and the instrument will self-test.
3. According to the needs, set the detection mode (real-time or timing), alarm value, display mode and other parameters through the menu.
4. Extend the sampling tube into the area to be tested, and the instrument automatically inhales the gas through the built-in pump for detection.
5. Observe the real-time concentration, Linear dispersion, temperature and humidity information displayed on the screen.
6. During the detection process, if the gas concentration exceeds the limit, the instrument will issue a sound and light vibration alarm.
7. After the test is completed, the stored data can be viewed locally or uploaded to the computer for analysis through the USB interface.
8. After use, shut down and keep it safe.
Notice
Do not replace batteries or charge them in dangerous areas.
• Avoid strong impact or falling of the instrument.
• Regularly calibrate to ensure detection accuracy, and the instrument has a calibrating reminder function.
• When using in a high dust or high humidity environment, make sure the Filter is in good condition and check and replace it regularly.
• When detecting high temperature flue gas, a special high temperature sampling cooling filtrate handle must be selected.
Sensor life (electrochemistry 2-3 years, catalytic combustion 3 years), should be replaced in time when it expires.
When the instrument alarms, appropriate safety measures should be taken immediately.
• Do not disassemble or modify the instrument yourself.
• Please use a matching or approved USB charging device for charging.
