The DR-123A Flue Gas Automatic Quality Control System can remotely receive instructions to supply a known concentration standard gas to the Continuous Emissions Monitoring System (CEMS). By analyzing the difference between the test feedback results from the monitor and the standard gas values, it can verify 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 perform their regulatory functions.
The quality control system features a direct connection to the standard gas sampling head, ensuring comprehensive quality control throughout the process and effectively detecting dilution and adsorption issues caused by the sampling line.The system is equipped with sensors at critical points, enabling remote monitoring of standard gas quantity, pressure, and flow rate, effectively detecting any leaks in the standard gas and ensuring the effectiveness of quality control.
Product Features
Remote Control Function: The device features both manual and automatic operation modes.All functions can be remotely set, with the quality control system software enabling operations such as equipment start/stop, random inspection control, parameter settings, and receiving random inspection results.
Full-process Quality Control: Standard gas sampling head connected, entering the monitor through the sampling pipeline for full-process quality control(Distinct from instrument quality control where standard gas is directly fed into the monitor)
Scheduled Random Inspection Function: Allows for the flexible setting of a schedule, with a certain flow of standard gas being introduced at the times specified in the schedule.The CEMS online monitor analyzes the indoor environment, receives CEMS analytical data, compares the data with standard gas concentrations, and uploads it; the data can be saved for 1 year.
Real-time random inspection feature: capable of receiving remote instructions at any time to initiate random inspectionsAutomatically verify random inspection results, save inspection records simultaneously, and upload them; records are retained for 1 year.
The equipment can monitor the analysis results of flue gas analyzers in real-time, upload exceeding data to the quality control system and automatically save it, automatically filter out data anomalies and data distortions, and provide corresponding suggestions.
The equipment can facilitate data statistics.(Including random inspection records, fault information, etc.), and wirelessly transmit to the quality control system, with data retained for one year.
Fully enclosed access control structure, password authorization protection, capable of saving door access records100 pieces
Intelligent Diagnostics: Allows for remote retrieval of standard gas quantity, pressure, quality control flow, and other information. Automatically alarms in the event of a fault.;
Power Failure Alarm Protection Function: The equipment is equipped with an internal power supply, which can automatically switch to the internal power supply in case of a sudden power outage. The device returns to standby mode, and the instrument data is not lost after power failure. Simultaneously, an alarm is sent to the backend platform, and a power failure record is saved.;
Communication Function: Equipped withMultiple interfaces including RS-232, digital I/O, and 4mA~20mA.

Remote Quality Control System
Derun Hou Tian has been committed to the research, development, and production of water quality automatic samplers and online monitoring instruments since its establishment. The company's equipment, with multiple categories and grades, has passed the China Environmental Protection Product Certification./Measuring certification, qualified in multiple national inspections.
Our company independently developed a remote quality control system, which is divided into a remote online automatic water quality monitoring quality control system and a remote online automatic flue gas monitoring quality control system. The flue gas remote online automatic monitoring quality control system consists of on-site quality control hosts, standard gases, and a remote quality control supervision platform. Instructions are sent from the remote quality control supervision platform to the on-site quality control hosts, which then control the delivery of standard concentration gases to the on-site flue gas online monitoring equipment for verification and data supervision.
Application Value
