ZHK2405 Intelligent High-Flow TSP Sampler

Main Features

1. Utilizes high-precision pressure, temperature, and flow sensors along with  microcontroller measurement and control technology to automatically  control the flow rate of the suction pump, achieving constant flow sampling.

2. Automatically measures environmental temperature, atmospheric pressure,  pre-sampling temperature, pre-sampling pressure, flow rate, and other  parameters. 

3. Digitally sets sampling flow rate (working conditions), sampling time,  interval sampling time, sampling volume, and other parameters. 

4. Digitally calibrates values for flow, temperature, pressure, time, and other  metrics. 

5. Automatically displays values for flow rate, sampling volume, temperature,  pressure, sampling time, power outage duration, and other metrics. 

6. Overload automatic protection: If the sampling flow deviates from the set  flow rate by more than ±10% for 5 consecutive minutes during sampling, the  instrument automatically shuts down for protection. 

7. Power outage protection function: If a power outage occurs during  sampling, the device can automatically save the sampling data and resume  sampling once power is restored. 

8. Capable of storing 100 sets of sampling data and power outage data. 

9. Uses a brushless fan, which has a long service life and can operate without  failure for 10,000 hours. 

10. The system is well-integrated, featuring a convenient assembly and disas-sembly method, along with effective protective measures. 

11. PM10 and PM2.5 cutting devices come with a test certificate.
