KD-2040TypeCODAmmonia nitrogen and total phosphorus analyzer

1Instrument features

1.Separating the digestion instrument from the measuring instrument does not affect the measurement. temperaturePIDAutomatic temperature control and timing.

2.Time saving operation.CODDissolve only requires15min.

3.Cold light source, narrowband interference optical system, good optical stability.

4.Equipped with calibration tube function to ensure measurement accuracy.

5.Can be saved separatelyCODStandard curves for ammonia nitrogen and total phosphorus10Article and999The measured value is not lost when the power is turned off.

6.LCDLarge screen LCD display, easy and intuitive operation.

7.It has printing function (printer is an optional accessory).

8.The host chassis is molded by compression moldingABSThe material has good corrosion resistance.
