YHCOD-400COD rapid analyzer

YHCOD-400 typeCOD rapid analyzerOverview: This instrument is widely used for the determination of surface water, groundwater, sewage, and industrial wastewater. This instrument has the following advantages: 1. The measuring instrument is separate from the digestion instrument and does not affect the stability of the optical system. 2. The measuring instrument is a cold light source and narrowband interferometric optical system with good optical stability. 3. The digestion instrument has PID automatic temperature control and timing, with high accuracy. 4. Simple and time-saving operation. Dissolving colorimetric does not require changing the tube. 5. The digestion temperature and time can be infinitely set for other purposes. 6. It can save 10 standard curves and 99 measured values each, without losing them when powered off. 7. LCD large screen LCD display, easy and intuitive operation. 8. Equipped with factory working curve recovery function. 9. Printing function: It can print test records immediately or query records for printing. 10. USB interface, can be connected to a computer.
