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. Feature Highlights Operation Modes: Manual and Automatic Modes Quality Control Methods: Immediate QC, Scheduled QC, Periodic QC Remote Mode: Achieve quality control result inquiries, categorization statistics, automatic detection of data quality reports, and personnel permission management through remote control systems. Operation Modes: Internal Quality Control, External Quality Control Modular design: One display controller manages multiple quality control terminals, with each terminal corresponding to a single online monitoring instrument. Distributed Layout: Compact design, quality control terminal located near online analytical instruments, short sample liquid transmission distance, local space occupation less than 0.1 m³. Idle Time Quality Control: Intelligent judgment and analysis of instrument idle time. Self-inspection and alarm: Self-inspection detects malfunctions and triggers alarms (e.g., for missing standard samples, failed standard samples, and can also provide low-liquid warnings for standard solutions), and automatically alarms when quality control results exceed the standard. Access Control Function: Electronic Access Control, Password Authorization Login Timing Calibration: Immediate calibration and daily scheduled automatic calibration modes available, calibration time can be set as required; Power Failure Data Retention: In case of power outage, quality control instrument data is retained, and power failure time is uploaded to the remote control platform. Multiple communication methods: Local control systems and remote control systems: Wireless, wired; local control systems and other control platforms: RS-485, RS-232.
