3、 Product Features

1. The entire equipment is designed as a combination: sampler, flow control, refrigeration and dehumidification device, moisture collector, heating sampling tube, adsorption tube, dryer and other functional units are organically combined, with a compact structure, lightweight and portable;

2. The inner tube of the sampling tube is made of anti adsorption polytetrafluoroethylene material, with full heat tracing throughout the process;

3. The program controls the switching between the main sampling adsorption tube and the bypass adsorption tube without manual intervention, resulting in more accurate control;

4. A 2-micron fine filter is installed in front of the adsorption tube to effectively remove the influence of dust particles;

5. The adsorption tube is equipped with a moisture separator, which effectively removes the influence of water vapor on the adsorption tube;

6. The adsorption tube is built into the refrigeration box to improve the adsorption efficiency of the adsorption tube;

7. Constant temperature control, automatic start heating at low temperatures;Juchuang Environmental Protection Waste Gas VOCs SamplerHigh temperature adopts high-power semiconductor two-stage refrigeration and adds blue ice auxiliary refrigeration function to ensure that the refrigeration temperature reaches (0-5) ℃;

8. The sampling tube adopts a PID high-precision temperature controller, with a control accuracy better than 2 ℃;

9. Large data storage, capable of storing up to 1000 sets of sampled data.
