ZHK2405 Intelligent High-Flow TSP Sampler

● 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. 

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

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

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

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

● 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.

● 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.

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

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

● The system is well-integrated, featuring a convenient assembly and disassembly method, along with effective protective measures.

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