COD-1020 COD analyzer

1、 Product Introduction

The COD-1020 COD analyzer utilizes sealed catalytic digestion followed by colorimetric measurement. The instrument adopts advanced cold light source, narrowband interference technology, and microcomputer automatic data processing to directly display the COD (mg/L) value of the sample. This instrument is widely used in environmental monitoring, sewage treatment, colleges, research institutions and other departments.

2、 Instrument features

1. The separation of the measuring instrument and the digestion instrument 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. Each can save 10 standard curves and 500 measured values without losing them when powered off.

7. LCD large screen LCD display, easy and intuitive operation.

8. It has printing function: it can print the test records immediately or query the records for printing.

9. USB interface, can be connected to a computer.
