HT-2400 Atmospheric Sampler (Rotary Flow Meter)

1、 Execution standards

JJG956-2000 Atmospheric Sampler

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

2、 Purpose:

The use of solution absorption method to collect harmful gases in ambient air and indoor air is an ideal product for environmental protection, labor hygiene, scientific research, meteorology, factories and mines to conduct atmospheric monitoring and related research work.

3、 Performance characteristics

1. It is controlled by a microcomputer, simple to use, reliable in performance, compact in size, and easy to use. It uses a wide temperature OLED screen to display images and text.

2. The volumetric rotary vane pump made of imported DC brushless motor is used as the sampling power, with automatic lubrication, all stainless steel pump body, high suction negative pressure, stable flow rate, and a running time of more than 20000 hours.

3. Dual use of AC and DC, with a built-in high-performance lithium battery that can be used in the absence of AC power. The built-in intelligent heater can sample at low temperatures, and the intelligent heater automatically heats the sampling bottle.

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

5. Clear automatic lighting function of the flowmeter, accurately and quickly reading the set flow rate.

6. Equipped with a rechargeable battery, it can store data during AC power outages, automatically restore sampling during AC incoming calls, deduct the power outage time during the sampling process, and allow users to query the power outage time.

7. Tripod cloud desktop design, easy to operate, with USB for USB data export.
