Professional COD Analyzer

Introduction of Professional COD Analyzer

Professional COD Analyzer is the use of sealed catalytic digestion, and then colorimetric measurements. The instrument uses advanced, narrowband interference technology and microcomputer automatic processing of data, direct display. The instrument is widely used in environmental monitoring, wastewater treatment and universities, research institutes and other departments.

Feature of Professional COD Analyzer

1. Professional COD Analyzer with digestion device, does not affect measurement accuracy. PID automatic temperature control, automatic timing.
2.High-performance ultra-low power 16 bit microcontroller, standby time of the instrument is up to six months or more.
3.Operation save time, COD digestion just 10min.
4.Cold light, narrowband interference optical system, good optical stability.
5.Data power protection.
6.COD can be saved for each standard curve 50 and 199 measured values (with a time label with the year, month, day, hour, minute and second values of COD, absorbance and transmittance)
7.With a USB port, you can join the computer to record read.
8.LCD large-screen LCD for easy and intuitive operation.
9.Host chassis with molded ABS material, IP65 design, waterproof and dustproof performance.
10.With calibration tube function, eliminating the optical differences digestion tubes, to ensure accuracy.
11.Optional printing function and emergency backup battery.
