HM-840 four parameter water quality detector

Introduction:

HM-840 four-parameter water quality detector has high precision, wide range of use and powerful COD/ammonia/total phosphorus three-parameter detector. It is widely used in research institutes, large and medium-sized water plants and industrial and mining enterprises, domestic or industrial water. The concentration of COD/ammonia nitrogen/total phosphorus in wastewater.

Features:

1. Batch inspection: equipped with 4 water sample detection positions, intelligent multi-channel detection structure design, simultaneous detection of multiple water samples, strong batch processing ability, fast detection speed, solving the problem of slow detection of multi-point water samples. Greatly improved detection efficiency.

2. Reference channel: The instrument is equipped with a fixed reference channel. During the detection process, the reference concentration and the sample concentration can be directly read at the same time, which improves the detection accuracy and avoids the error of manual operation.

3. Filter: 3 wavelength filters are standard, which meets the requirements of high COD, COD low range, ammonia nitrogen, total phosphorus and total nitrogen.
