Overview
WD9103B Portable water quality tester is a JINGQI brand product. It is designed separately from the digestion instrument and does not affect the measurement accuracy. The instrument can measure total nitrogen parameters, and the measurement range is 0.05~ 100mg/L, with High Accuracy and stability.
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 uses cold Illuminant and narrow-band interference Optical inspection system for Optical inspection measurement, and the measurement process is controlled by high-performance single-chip microcomputer. The digestion instrument and the measuring instrument work separately, and the digestion temperature can be set. The total nitrogen digestion temperature is 125 ° C to ensure the measurement accuracy.
