Environmental Air Waste Gas VOCs Sampler

GR-3030 waste gas VOCs sampler

1. Product Overview

Environmental Air Waste Gas VOCs SamplerIt is a sampler developed by our company that uses solid-phase adsorption to collect volatile organic compounds from fixed pollution sources. It can also collect volatile organic compounds such as benzene derivatives, aldehydes and ketones, and halogenated hydrocarbons in ambient air. The product consists of a sampling pumpThe combination design of flow control unit, condensation dehumidification unit, heating sampling tube and other functional units is compact, lightweight and portable. Widely used in environmental protection, hygiene, labor, safety supervision, militaryDepartments such as scientific research and education.

2. Scope of application

Suitable for collecting 24 volatile organic compounds from fixed pollution sources using solid-phase adsorption method. Can be used by departments such as environmental protection, health, labor, security, military, scientific research, education, etc.

4. Technical 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. Dual sampling of main and bypass paths, automatic control, no need for manual intervention, more accurate control;

3. The moisture separator with built-in semiconductor refrigeration effectively removes moisture from the flue gas, preventing water vapor from entering the adsorption tube and affecting the measurement results;

4. The adsorption tube is built into the refrigeration box to maintain an ideal temperature environment (0-5 ℃) and improve the adsorption efficiency of the adsorption tube;

5. Cascade adsorption tubes can be installed after the main adsorption tube to test whether the adsorption tube penetrates.

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

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

8. The front end of the sampling tube is equipped with a 2-micron fine filter, effectively removing the influence of dust particles;

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

10. Optional Bluetooth printing, printing and outputting test data
