High performance portable gas detector is a suction and diffusion dual-purpose device. When the air pump fails or in special emergency situation, it can automatically switch to the diffusion sampling method, thereby improving the protection to a new level.

Functions

• The portable gas detector can effectively resist a three-meter drop, has passed the EMC anti-static interference test and can work normally in the walkie-talkie environment.
• It has got IECEX, ATEX, explosion-proof certificates and the explosion-proof level reaches Exia IICT4 Ga. The man down alarm function has upgraded the safety of underground operators.
• Password protection function prevents non-operators from modifying menu parameters. With safety reminder function, sound and light vibration alarm function, let operators work without worries. The high and low alarm latched function allows the operator to better capture the sudden change of the gas concentration value.
• Real-time value, TWA, STEL, MAX, MIN multiple numerical display, and the screen can be automatically turned 180 degrees, which is convenient for viewing in special operating environments.
• Built-in powerful sampling pump, fast detection speed. It can be connected 20m sampling tube externally, which is convenient for long-distance or confined space detection.
• Pump suction and diffusion dual use, to provide operators with more reliable protection. With a water trap filter, it can effectively filter water, oil, dust and other impurities. It can also be used in harsh industrial environments such as coal mines and petroleum fields.
• Beautiful and friendly user interface, reasonable and easy-to-use interactive mode. Standard storage function, one-click data export, convenient for users to analyze.
• Unique modifiable ID identification function, convenient for users to allocate and manage the instrument. A full range of automatic detection functions, automatic prompts for voltage, pump failure alarms, etc., more comfortable to use.
• One-key open storage, automatic image flip. It supports each channel sensor to restore the factory setting separately and multi-language including English, Chinese and etc.

Tips: How to prevent the hydrogen leakage of the H2 gas detector?

The hydrogen gas detector is a personal portable gas detection alarm, which equipped with an electrochemical sensitive sensor. It is suitable for continuous detection of the percentage concentration of oxygen in the ambient air of industrial and mining enterprises. Low-limit sound, light, and vibration alarm to warn people on site to evacuate the dangerous area as soon as possible.

Measures to prevent hydrogen leakage from the H2 detector:

• Strengthen equipment safety management, and regularly check hydrogen pipelines that are prone to corrosion and damage with a hydrogen detector. The leaking pipeline was found to be repaired in time.
• Strict open flames appear on the road section of the hydrogen pipeline, and workers entering and exiting hydrogen use or transportation areas need to wear anti-static overalls. Use mobile phones or non-explosion-proof lighting tools strictly in areas where hydrogen exists, do a good job of insulating cable laying in the workshop; use more corrosive materials in the rigorous workshop.
• Strengthen employee safety awareness, launch safety knowledge training activities, and establish a sound safety management model.
• Install a fixed hydrogen alarm and use it with a hydrogen detector to realize 24 hours of uninterrupted online work anytime, anywhere, and achieve double protection.

Precautions for post-maintenance of H2 detector:

• The gas calibration has been done before leaving the factory. After installation, please do not change the components at will. If you need to replace it, you must re-calibrate.
• The normal service life is 3 years. Due to the difference in the use environment, its service life may be reduced, and inspection and maintenance should be carried out regularly every year.
• High-concentration hydrogen shock is forbidden in the parts to avoid poisoning the gas sensor and damaging the detector.
• During the use process, check whether the hydrogen gas detector is working normally, and the check period should be kept within 3 months at least.
