Application Overview

The Derun Hou Tian DR-103E Online Water Quality Automatic Monitoring Quality Control Instrument can accept remote control and provide known concentration standard samples or labeled water samples to the online monitor. By comparing the test feedback results with the known values, it can validate the operational status of the online monitoring equipment and the reliability of the monitoring data. It is an effective tool for environmental regulatory authorities to carry out their regulatory functions.

The quality control instrument is compact and small in size, allowing for tight installation adjacent to the monitoring instrument without requiring substantial space; the short standard sample transport distance effectively reduces pipeline transmission errors; one controller can cascade with multiple quality control terminals via 485, and adding measurement parameters only requires adding the corresponding terminal, making upgrades convenient, flexible, and cost-effective.

This product obtained the Environmental Protection Product Certification in April 2018, Certificate Number: CCAEPI-EP-2018-245.
