Product details

Purpose:

Suitable for collecting TVOC and SO in the air₂、 NOX、O₃、 NH₃Waiting for harmful gas samples.

Adopting standards:

HJ/T 375-2007 "Environmental Air Sampler"

JJG 956-2013 "Verification Regulations for Atmospheric Samplers"

Main features:

1. Adopting constant current sampling technology to automatically control the sampling flow rate.

2. Able to digitally set and calibrate sampling flow rate.

3. It can automatically measure environmental temperature and atmospheric pressure, and convert the sampling volume into standard sampling volume.

4. There are two independent sampling gas paths, and a drying bottle with anti backflow function is connected in series in the gas path.

5. Able to perform single or dual channel, timed, quantitative, and interval sampling.

6. Comes with a lithium battery, capable of sampling without AC power supply.

7. Install 4 absorption bottle mounting holes, as well as adapter components for 10mL, 50mL porous glass plate absorption bottles and 10mL impact absorption bottles, allowing for the installation of 4 absorption bottles at will.

8 . Wide temperature LCD display screen, 240 × 128 large screen, Han display.
