1、 Execution standards

JG956-2013Verification Regulations for Atmospheric Samplers

GB50325-2020Code for Indoor Environmental Pollution Control of Civil Building Engineering

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

2、 Purpose:

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, convenient to use, and can control four channels separately. It has a wide flow range and wider applicability.

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. Dual use AC/DC, with built-in high-performance lithium battery that can be used in the absence of AC power, with a continuous working time of more than 20 hours.

4. The left and right hanging absorption bottle holder is convenient to use, and the optional heater can sample at low temperatures. The intelligent heater automatically heats the sampling bottle to ensure good temperature insulation effect of the absorption bottle.

5. 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.

6. It has energy-saving automatic protection function and can control all four channels separately. It has multiple sampling methods such as simultaneous sampling, individual sampling, multiple sampling, alternate day sampling, and cyclic sampling.

7When there is a power outage during communication, data will be automatically saved. When there is an incoming call, sampling will be automatically restored, and the power outage time during the sampling process will be automatically deducted, which can be queried by usersElectricity time.

8, can be done throughRS232The interface can be equipped with a micro printer for data printing, and can also be accessed throughUExport the disk and the host can automatically recognize itUDisk capacity.

9Automatically accumulate the sampling volume, and simultaneously convert the accumulated standard sampling volume, reference sampling volume, etc. based on the self measured air pressure and temperature.

10Automatically detect the power supply status. During the sampling process, if there is a power outage, the sampling data will be automatically saved. When there is a power outage, the sampling will be automatically restored and the power outage time will be deducted.

11Maintain menu with password to ensure data security.

12Adopting imported high-capacity lithium battery cells, with longer sampling time and better low-temperature performance.
