Overview

WD9203B Portable water quality tester is a Portable testing equipment produced by JINGQI. It adopts a separate design of digestion instrument and measuring instrument to ensure measurement accuracy. The instrument is equipped with a high-performance ultra-low power consumption microcontroller, with long standby time and convenient operation, which is suitable for on-site rapid water quality testing.

Features

1. The digestion instrument is separated from the measuring instrument, which does not affect the Measurement accuracy. Temperature PID automatic temperature control and timing. 2. High-performance ultra-low power consumption 16-bit microcontroller, instrument standby time can reach more than 6 months. 3. Operation saves time. 4. Cold Illuminant, Narrow Band Interference Optical inspection system, Optical inspection Stability. 5. Data power-off protection function. 6. 30 standard Linear dispersions and 199 measured values can be stored each (including Measured value, light absorption value and light transmitance with time label year, month, day, hour, minute and second). 7. With a USB port, it can be connected to a computer for recording and reading or printing out stored data. 8. The main machine shell adopts molded ABS material, IP65 design, good waterproof and dustproof performance.

Principle

The instrument adopts the separation design of digestion instrument and measuring instrument, and the water sample is pretreated by PID automatic temperature control and timing through digestion instrument. The measuring instrument uses cold Illuminant and narrow-band interference Optical inspection system to measure the absorption or transmission changes of specific components (such as COD and total nitrogen) in the water sample to calculate the concentration value.

Applications

Water quality testing, environment monitoring
