Executive standard:
Notice on Accelerating the Automatic Monitoring of Key Pollutant Discharge Units in Key Industries and Key Regions"
(Environmental Office and Environmental Supervision (2017) No. 61
Features:
1. Sampling function: It can realize multiple sampling trigger methods such as timing sampling, time ratio, flow ratio, flow tracking, external control sampling and serial port control;
2. External pump control: directly control the external pump to increase the sampling distance.
3. Sample retention function: it can realize over-standard retention sample, synchronous retention sample, direct retention sample, serial port control retention sample;
4. Automatic emptying of the mixing tank: The mixing tank has the function of fast and automatic emptying;
5. Power-off protection: automatic protection when power-off, and automatically resume work after power-on;
6. Remote control (optional): It can realize remote status query, parameter setting, record upload, remote control and sample retention, etc.;
7. Digital temperature control: precise digital temperature control of the refrigerator, with a soaking system, uniform and accurate temperature;
8. Automatic rinsing: before each sampling, rinse the pipeline with the water sample to be tested to ensure the representativeness of the retained sample;
9. Records: with sample retention records, door opening and closing records, power failure records and alarm records;
10. Sample supply function: It can provide uninterrupted mixed water samples to multiple online monitors such as COD, ammonia nitrogen, and heavy metals at the same time.
