QCW-1000 Water Quality Online Quality Control Instrument

Product Overview

The QCW-1000 water quality online quality control instrument can be used to verify the reliability of the analysis data of water quality online analyzers, and can achieve functions such as standard sample verification testing, zero and span verification testing, parallel sample testing, blank sample testing, etc.

working principle

The QCW-1000 water quality online quality control instrument consists of two main parts: a display control module and a standard sample verification module. The display control module and configuration module are based on the 7-inch color display screen of the Android system. Users can perform internal control, parameter settings, record queries, and other operations, and activate remote quality control functions through serial ports or network interfaces. The standard sample verification module automatically prepares multiple parameters and concentrations of standard samples through high-precision plunger pumps, achieving standard sample verification testing, zero and range drift testing, and blank sample testing. The QCW-1000 online quality control instrument can be used in conjunction with multiple water quality online monitoring instruments to complete quality control operations such as water sample testing, parallel water sample testing, and standard sample verification.
