    High performance portable gas detector has humanized operation functions such as one-key security detection, one-key storage, automatic image flipping, as well as the man down alarm function. The compact design makes it easy carrying.

    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.

    Applications

    Applications of Portable Multi Gas Detector

    Tips for using explosion-proof multi gas detector

    • Pay attention to the measuring range of the portable gas detector used:
      Any gas detector has a fixed detection range, and the measurement can only be completed within this range, otherwise the measured result is much lower than the value of your environment. In addition, measuring over the range for a long time will cause damage to the sensor, so that the correct result cannot be obtained in the measurement range later.
    • Pay attention to the service life of the sensor in the gas detector used:
      Gas detectors have a limited service life, and portable gas detectors are no exception. Even if they are not used frequently, they will still experience aging. In general, among the portable gas detectors, the photoionization detector has the longest lifespan of about four years; the lifespan of the LEL sensor is the second, which can be used for more than three years; the lifespan of the electrochemical specific gas sensor is relatively short, Generally within one to two years; the oxygen sensor can only be used for about one year.
      Therefore, be sure to read the instruction carefully before use, and use it within the validity period of the sensor. If it is found to be expired, it needs to be replaced immediately.

    The detector needs to be calibrated and tested frequently.
    Portable gas detectors generally adopt a relative comparison method for measurement, and the measurement method is as follows:

    1. First calibrate the instrument with a standard concentration of gas and a zero gas, and obtain the standard curve and store it in the instrument;
    2. Compare the electrical signal of the standard concentration with the electrical signal generated by the concentration of the gas to be measured, and obtain an accurate gas concentration value after calculation.
