  • Product Introduction
  • 1. Product introduction


    The instrument uses the solution absorption method to collect various toxic and harmful gases in the ambient atmosphere and indoor air, and uses the filter membrane weighing method to capture the total suspended particles (such as TSP, PM 10 , PM 2.5 , etc.) in the ambient atmosphere. Widely used in environmental protection, occupational health, factories and mines, colleges and universities, scientific research and other institutions.

    2. Product Features


    Electronic flowmeter, constant current sampling, two channels of atmospheric 0.1-1.0L/min, one channel of particulate matter 60-130L/min;

    The high-speed processor automatically calculates and controls the sampling flow, and automatically compensates for flow changes caused by voltage fluctuations and resistance changes;

    The atmosphere uses high-performance ultra-bass imported diaphragm pump, which greatly improves stability, long service life and ultra-low noise;

    Atmospheric sampling two-way design, flexible sampling method, can collect two kinds of gases or parallel samples, and can be controlled separately;

    The particle sampling adopts brushless control fan, which has low noise and large load, and is suitable for continuous long-term work;

    Automatically measure ambient atmospheric pressure and temperature, display real-time sampling flow, accumulated sampling volume, and standard volume;

    Built-in real-time clock, the sampling start time can be preset;

    Timing sampling can be set, sampling multiple times at equal intervals, and the sampling times can be arbitrarily set between 1 and 99;

    During the sampling process , the current sampling state is automatically memorized, and the previous sampling is automatically restored when the power is turned on again;

    High-quality dust filter element is used in the atmosphere to realize the function of particle filtering, prevent entering the gas path to interfere with sampling, and protect the sampling pump and gas path at the same time;

    Atmospheric sampling has automatic heating function;

    The air is designed with high-efficiency anti-suckback dryer, which can effectively prevent the absorption liquid from being sucked back due to misoperation, and enhance the safety of the instrument;

    In the process of atmospheric sampling, if the pipeline is blocked or the load is too large, the system will automatically stop the pump to protect the instrument from being damaged due to long-term overload. When the load is greater than negative 20kPa for a long time, the protection function is automatically activated;

    With RS232 digital communication interface, optional external printer, convenient data output;

    The Chinese LCD screen with automatic contrast adjustment is suitable for sampling in the cold area of minus 30 degrees, and the popular software display interface realizes good human-computer interaction;

    Optional data export, data printing and GPS positioning functions;

    Atmospheric sampling adopts a special gas connection pipe, which can be easily and accurately connected to the gas path;

    TSP/PM10 / PM2.5 sampling head is made of aluminum alloy material, anti-static adsorption;

    Power failure protection function, automatic sampling of incoming calls;

    The instrument has a built-in large-capacity lithium battery, which can sample normally without AC power;

    Equipped with a height-adjustable tripod;

    Professional metrology certificates issued by professional metrology institutes can be provided;

    Optional sample storage device to facilitate the collection and storage of particulate samples;

    It has a type approval certificate ( CPA) for measuring instruments, which can be sent to the Metrology Institute to issue a verification certificate;

    The instrument has won the national new patent certificate (patent number ZL 2019 2 0148009.5).
    The instrument is loaded with the medium-flow particulate matter sampling system software and atmospheric sampling control system software that have won the computer software copyright (certificate number: Ruan Zhu Deng Zi No. 4181060, Ruan Zhu Deng Zi No. 4181060 No. 4182741)
