used the sealed digestion to digest water samples, and the use of advanced cold-light source, narrow-band interference technology, Microcomputer automatic processing of data to direct indication of the sample COD (mg / L) values. The instrument is widely used in various industries, environmental monitoring, sewage treatment and universities, research institutes and other departments.
＊Parameters:

＊The product has the following main features:
1．Use of cold light, monochromatic source, well optical stability, will not be subject to a variety of light interference.
2．Use the PID to automatic control the digestion temperature, and high precision.
3．Two-line LCD display, easy to operate.
4．High-temperature digestion and colorimetric (including the host) separation of the two parts, down the impact of temperature on the optics to a minimum.
5．High efficiency, digest 20 water samples once，determination of time of each batch of water samples is only about 20 minutes.
6．Data will not lost when the power break off.
