DR-103E water quality online automatic monitoring and quality control instrument can accept remote control to the online monitor to provide a known concentration of standard samples or standardized water samples, through the monitor to test the results of the feedback and the known value of the difference between the monitoring instrument can be corroborated by the operational status of the online monitoring equipment and the credibility of the monitoring data. It is an effective tool for environmental regulators to carry out their regulatory functions.
The quality control instrument is compact in design and small in size, and can be installed close to the monitor in a distributed manner without occupying a large space; the specimen is delivered over a short distance, which effectively reduces pipeline transmission errors; a controller and multiple quality control terminals are cascaded through the 485 cascade, and the increase in measurement parameters only requires the addition of the corresponding terminals, which makes upgrading convenient, flexible and cost-effective.
The product obtained the certificate of environmental protection product certification in April 2018, Certificate No.: CCAEPI-EP-2018-245.

QC modes: immediate QC, timed QC, periodic QC;
Remote mode: Through the remote control system to realize the quality control results query, classification statistics, automatic testing data quality report, personnel rights management;
Operation mode: internal quality control, external quality control;
Modularization: a display controller to control a number of quality control terminals, each quality control terminal corresponds to an on-line monitoring instrument;
Distributed layout: small size, quality control terminals are placed next to the on-line analytical instrument, the sample liquid transferring to the instrument. Distributed layout: small size, QC terminal is placed next to the on-line analyzing instrument, short transmission distance of sample liquid, local occupied space less than 0.1m?;
Idle time QC: Intelligent judgment of analyzing instrument idle time;
Self-inspection and alarm: Faults can be detected and alarmed through self-inspection (e.g., lack of standard samples, standard samples failures, and realize the lack of standard liquid early warning), and the exceeding of the standard of QC results will be alarmed automatically;
Gate control Function: electronic access control, password access;
Clock calibration: immediate calibration and daily timed automatic calibration of two modes, calibration time can be set according to demand; power failure data retention: fault power failure, quality control instrument data retention, power failure time uploaded to the remote control platform;
Multiple communication modes: the local control system and the remote control system: wireless, wired, the local geological control system and other control platforms: RS-485, RS-486, RS-486 and other control platforms.
DR-123A flue gas online automatic monitoring and quality control system
DR-123A flue gas automatic quality control system can accept remote instructions to the flue gas online monitor (CEMS) to provide a known concentration of the standard gas, through the monitor to test the results of the feedback and the difference between the value of the standard gas can be corroborated by the on-line monitoring equipment The difference between the test results and the standard gas value of the monitor can confirm the operation status of the online monitoring equipment and the credibility of the monitoring data. It is an effective tool for environmental regulators to carry out their regulatory functions.
The quality control system standard gas from the sampling head access, for the whole process of quality control, can effectively check out the sampling pipeline caused by the dilution, adsorption problems; the system is equipped with sensors in key links, can be remotely informed of the standard gas quantity, the standard gas pressure, the standard gas flow rate, etc., can be effective in perceiving whether the standard gas is leaking, whether the quality control is effective.
Product features
Remote control function: the device has two working modes: manual and automatic; can be set remotely all the functions, the application of the quality control system software to realize the start and stop of the device, sampling control, parameter settings and receive sampling results and other operations;
The whole process of quality control: the standard gas is accessed from the head of the sampling, and enters into the monitor through the sampling pipeline, which is the whole process of quality control. Standard gas directly into the monitor instrument quality control)
Timed sampling function: you can freely set the timing table, according to the time in the timing table will be a certain flow rate of standard gas into the CEMS online monitor analysis chamber, and receive CEMS analysis data, analysis data and standard gas concentration comparison and uploading, the data can be saved for 1 year;
Instant sampling function: at any time to receive remote instructions to start the sampling function. Receive remote commands to start the sampling function; automatically check the sampling results, automatically save the sampling record and upload it at the same time, the record can be saved for 1 year;
The equipment can monitor the analysis results of the flue gas analyzer in real time, and find out that the data exceeding the standard is uploaded to the quality control system and automatically saved, and it can automatically screen out the information of data anomalies and distortion of the data, and provide the corresponding recommendations.
The equipment can realize data statistics (including sampling records, fault information, etc.), and wireless transmission to the quality control system, data retention for one year;
The fully enclosed access control structure, password privilege protection, and can save the opening and closing of the door record 100;
Intelligent diagnostics: Remote access to the number of standard gas, standard gas pressure, quality control flow rate, etc., and automatically alarm in the case of a malfunction. Alarm;
Power failure alarm protection function: the equipment is equipped with self-supporting power supply, after a sudden power failure, it can be automatically switched to the self-supporting power supply, and the equipment will return to standby mode, and the data of the instrument will not be lost after the power failure. At the same time alarm to the background platform, and save the power failure record;
Communication function: RS-232, digital I/O, 4mA ~ 20mA and other interfaces.
