1、 Execution standards

JG956-2013 "Verification Regulations for Atmospheric Samplers"

GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering"

HJ/T375-2007 "Technical Requirements and Testing Methods for Environmental Air Samplers"

2、 Product Usage

This instrument uses methods such as solution absorption or activated carbon tubes to collect harmful gases such as formaldehyde, ammonia, benzene, TVOC, SO2, NOx, etc. in the environment and indoor environment. It is an ideal choice for environmental monitoring, engineering quality supervision, and health and epidemic prevention departments to collect various toxic and harmful gases.

3、 Performance characteristics

1. Adopting microcomputer control, it is easy to use, reliable in performance, compact in size, and convenient to use.

2. Adopting imported DC brushless motor vacuum pump, with high suction negative pressure, stable flow rate, and a fault free operation time of more than 20000 hours.

3. This instrument is equipped with an intelligent heater that can automatically heat the sampling bottle, and adopts a fully wrapped design for sampling at low temperatures.

4. The unique three in one design of drying, filtering, and anti backflow suction in the drying cylinder can efficiently dry moisture, filter dust, and reduce the impact of backflow suction on flow rate, achieving long-term operation without cleaning.

5. It has energy-saving automatic protection function, timed sampling function, and delayed sampling function.

6. Automatically save data during power outages, automatically restore sampling during incoming calls, deduct power outage time during the sampling process, and allow users to query power outage time.

7. Data printing can be done by selecting a micro printer through the RS232 interface, and it can also be exported through a USB flash drive with the host automatically recognizing the capacity of the USB flash drive.
