product overview
The water quality data quality intelligent diagnostic instrument is jointly developed by Jiangsu Environmental Monitoring Center and Jiangsu Delin Environmental Protection Technology Co., Ltd. It is divided into portable water quality data quality intelligent diagnostic instrument and online water quality diagnostic instrumentIntelligent diagnostic instrument for data quality,Has been granted patent protection for invention (patent number:2).The instrument consists of a sampling switching valve, a liquid preparation module, a communication module, a display module, and a control moduleThe circuit module is composed of an online diagnostic instrument with a small refrigerator added, which can store test samples for a long time.
Working principle
During on-site installation, the sampling tube of the diagnostic instrument is connected to the water sample tube of the assessed instrument, and the on-site water sample tube is connected to the sampling port of the assessed instrument. When the assessed instrument measures the on-site water sample, the diagnostic instrument takesExtract actual water samples from the sampling site and transport them to the assessed instrument for measurement. When diagnosing the accuracy of the data of the assessed instrument, the diagnostic instrument performs the assessment according to the set assessment time,Automatically prepare quality control samples with random concentrations for the tested instrument to measure. After the measurement is completed, the diagnostic instrument reads the measurement results displayed on the assessed instrument screen through the camera and analyzes them into the diagnostic instrument's historyThe historical data table, together with the concentration of the quality control sample prepared by the diagnostic instrument, is uploaded to the monitoring platform. Assessors can remotely monitor and query data in real-time through a mobile app to determine the instrument being assessedThe accuracy.

scope of application
Suitable for monitoring the accuracy of data from various online water quality monitoring instruments.
Problems with other similar products in the market
1. The existing water quality control instruments in the market are controlled by the assessed instruments;
2. The quality control sample sent by the quality control instrument to the assessed instrument is a known fixed concentration;
3. Provide opportunities for illegal personnel to falsify data.
Product Features
1 Independence
The diagnostic instrument does not require electrical connection with the tested instrument, and on-site installation does not require technical support from the tested instrument manufacturer.
2 Randomness
The random dispensing mode of the diagnostic instrument allows for the preparation of quality control samples with random concentrations, thus eliminating the possibility of fraud.
3 Authenticity
The quality control sample is a concentration automatically and randomly prepared by the diagnostic instrument after the assessment personnel set the assessment time, and the data is true and reliable.
4 Automation
The automatic measurement function of the diagnostic instrument, with one click operation, directly enters the working state, greatly facilitating law enforcement work.
5 Remote Localization
Through the remote control platform of the diagnostic instrument, the accuracy of the data of the tested instrument can be monitored by remotely operating the diagnostic instrument.
6 Multiple Parameters
The diagnostic instrument can be used for applications including but not limited to total phosphorus, total nitrogen, ammonia nitrogen COD、 Data monitoring of all online water quality monitoring instruments, including permanganate index.
7 Intelligence
Based on automation and remote functions, it reduces the manpower and material resources required for manual quality control to go to the site, providing an unmanned water quality data intelligent diagnostic instrument for management departments, and achieving quality controlControl and manage the Internet of Things.
