Overview
WD9205B Portable water quality tester is a professional testing equipment produced by JINGQI. It adopts the separate design of digestion instrument and measuring instrument to effectively ensure the measurement accuracy. The instrument has the measurement function of ammonia nitrogen and total phosphorus. Measurement range is 0.02~ 25mg/L and 0.00~ 10mg/L, respectively, suitable for on-site rapid water quality analysis.
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 is based on the Spectrophotometric method, spectra-trophotometry principle. During the measurement, the water sample is subjected to a specific Reagent reaction or digestion treatment. At a specific wavelength, the Absorption or light transmitance of the solution is determined by its Cold Illuminant and Narrow Band Interference Optical inspection system. The internal processor of the instrument calculates the concentration of the components to be tested (such as ammonia nitrogen and total phosphorus) according to the pre-stored standard Linear dispersion.
