Overview
WD9102B Portable water quality tester is a professional water quality testing equipment of JINGQI brand. It is designed separately from the digestion instrument to ensure that the measurement accuracy is not affected. The instrument has the function of PID automatic temperature control and timing, which is suitable for fast and accurate measurement of total phosphorus parameters. The measurement range is 0.02~ 10mg/L.
Features
1. Digestion instrument and measuring instrument are designed separately, without affecting the measurement accuracy, temperature PID automatic temperature control, timing
2. High-performance ultra-low power consumption 16-bit microcontroller, instrument standby time can reach more than 6 months
3. Time-saving operation
4. Cold Illuminant, Narrow Band Interference Optical inspection system, Optical inspection stability
5. Data power failure protection function
6. Standard Linear dispersion 30 and 199 measurement values (including measurement values with time label year, month, day, hour, minute, second, light absorption value and light transmitance)
7. With USB port, it can be connected to a computer for record reading or printing out stored data
8. The main cabinet is made of molded ABS material, IP65 design, good waterproof and dustproof performance
Principle
The instrument adopts cold Illuminant and narrow-band interference Optical inspection system to detect the total phosphorus content in water samples through Optical inspection stability. During the digestion process, the temperature is automatically controlled by PID at 120 ° C +/- 1.0 ° C for 30 minutes, and then the data is processed by high-performance single-chip microcomputer to achieve accurate measurement.
Applications
Water quality testing, environment monitoring
Standards
Indication Error ≤ +/- 5% FS or 0.2mg/L, sexual repeability ≤ 3%, Optical inspection stability ≤ 0.002A/20min
