Practical COD Rapid Detector

 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:

※ Measuring range:5～2000mg/L（if over the range, dilution metering）

※ Anti-jamming Cl: ≦1200mg/L

※ Wavelength: 610nm

※ Heating temp.: 165±1.5℃

※ Heating time: 10 minutes

※ Optics stability: absorptance drift is less than 0.002A in 20 minutes

※ Batch number: 20 water samples

※ Max power dissipation: 400W

※ External dimension: colorimetric part: 210×280×190mm;

                                      heater part: 200×240×190 mm

＊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.
