Product Description

The product meets the requirements of GB / T 15432-1995 gravimetric method for determination of total suspended particulates in ambient air, JJG 943-1999 verification regulation of TSP sampler, HJ / t374-2007 technical requirements and detection methods of TSP sampler, HJ / T 375-2007 ambient air sampler technical requirements and test methods, Q / wth 04-2017 th-150 medium flow atmospheric particulate matter


Features


  • The three sampling flows are all automatic constant flow and digital flow display, which avoids the disadvantages of manual adjustment of flow rate, inaccurate flow rate and falling float when using Rotameter for gas sampling;

  • Adopt original imported built-in air pump, high reliability and strong anti load ability;

  • The inlet flow sensor is equipped to detect the sampling flow, and the microcontroller automatically compensates the flow change caused by the change of voltage and resistance to make the flow measurement more accurate;

  • The instrument can realize simultaneous or separate sampling of particulate matter and two gaseous pollutants;

  • 4.3-inch color touch screen display and operation, clear and visible in the sun;

  • The three channels can automatically accumulate the sampling volume and the reference volume respectively, and can set the sampling time and flow rate respectively;

  • With the function of software calibration, the parameters such as flow rate, temperature and atmospheric pressure can be easily calibrated through the touch screen;

  • The instrument has the functions of storage, inquiry and printing (printer is optional), and each channel can store 200 groups separately;

  • The instrument is small in size, light in weight and easy to carry;

  • Equipped with DC battery, the instrument can work for more than 20 hours (only particulate matter sampling, domestic glass fiber filter membrane, flow rate of 100L / min). Meet the requirements of 24-hour effective sample;

  • It has external power interface.


Scope Of Application

Thh-h is a new type of gas sampler developed by our company. The new energy-saving brushless pump (which has been patented) can maintain the flow rate of 100L / min continuously by using the built-in battery, and the sampling can be completed without stopping the machine after the mains power is off. It is an ideal instrument for environmental assessment and on-site monitoring.
