QCW-1000 water quality online spiked recovery instrument

Product Overview

The QCW-1000 water quality online spiked recovery instrument is mainly used as an auxiliary instrument for detecting the reliability of analyzers. It can be used in conjunction with water quality analyzers such as total phosphorus, total nitrogen, ammonia nitrogen, and permanganate index to achieve spiked recovery testing.

Suitable for various water station platforms, it can be used for testing preparation of spiked recovery of total phosphorus, total nitrogen, ammonia nitrogen, and permanganate index instruments. The preparation includes water sample preparation and spiked water sample preparation. On the upper computer, simply select the test items that need to be executed and input the required concentration of the spiked solution to automatically execute the entire process without human intervention.

working principle

The QCW-1000 water quality online spiked recovery instrument consists of two main parts: a display control module and a water sample spiked module. The display control module and labeling module are based on the Android system's display screen. Users can perform internal control, parameter settings, record queries, and other operations, and activate remote labeling functions through serial or network interfaces. The core of the water sample labeling module is to achieve labeling measurement through high-precision plunger pumps, thereby completing labeling recovery testing.

Product Features

● Small chassis size
● Belonging to the same slave as the analyzer, there is no interference with each other
The labeling recovery instrument can be used in conjunction with the QCW-1000 quality control instrument, or a separate controller can be selected
When equipped with a built-in controller, it can work independently without the control of an upper computer
Using a high-precision plunger pump for volumetric titration of mother liquor, making the standard addition measurement more accurate
● Real time alarm and record of communication issues
