Overview
WD9202B Portable water quality analyzer is a professional water quality analysis equipment of JINGQI brand. It adopts the separation design of digestion instrument and measuring instrument to effectively ensure the measurement accuracy. The instrument is equipped with a high-performance ultra-low power consumption microcontroller, with long standby time and data power-off protection function. It is suitable for rapid detection of chemical oxygen demand (COD) and total phosphorus (TP) content in water quality on site.
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 works based on the Spectrophotometric method, spectra-trophotometry principle. After the water sample is digested at a specific temperature and time in the digestion instrument, the substance to be tested reacts with the Reagent to form a colored compound. The cold Illuminant and narrow-band interference Optical inspection system in the measuring instrument emits light of a specific wavelength. By measuring the Absorbance of the colored solution to the light, the concentration value of chemical oxygen demand (COD) or total phosphorus (TP) in the water is calculated according to the built-in standard Linear dispersion.
Applications
Environmental protection monitoring, sewage treatment, industrial production process control, scientific research experiments, water quality investigation
Standards
Chemical oxygen demand (COD) measurement conforms to relevant national water quality testing standards, total phosphorus (TP) measurement conforms to relevant national water quality testing standards
Steps
1. Prepare the water sample to be tested and the supporting Reagent.
2. Add the water sample and Reagent to the digestion tube and put it into the digestion instrument for digestion.
3. After digestion is complete, remove and chill down to room temperature.
4. Place the digestion tube into the tester sample chamber.
5. Select the corresponding item (such as COD or total phosphorus) on the instrument interface for measurement.
6. Read and record measurement results, data can be exported through USB port.
Notice
• Please read the instructions carefully before use and strictly follow the operating procedures.
• Reagents are within the valid period and stored correctly.
• The digestion process involves high temperature, please pay attention to the safety of operation to prevent burns.
• When measuring different items or different ranges, make sure to use the correct standard Linear dispersion.
• Keep the outer wall of the Cuvette or digestion tube clean to avoid fingerprints or stains affecting the Measurement accuracy.
• When the instrument is not in use, please keep it in a drying place.
• If the instrument malfunctions, please contact a professional to repair it, and do not disassemble it yourself.
