JC-COD-100K handheld COD analyzer

1、 Product Overviewnarrate, recount, state
The Juchuang JC-COD-100K handheld COD analyzer is designed and developed based on the "HJ/T 399 Determination of Chemical Oxygen Demand in Water Quality - Rapid Digestion spectrophotometric method". It can accurately and quickly determine the COD index of water samples and is suitable for detecting general environmental water samples such as surface water and groundwater, as well as water samples with moderate to mild pollution.
The JC-COD-100K handheld COD analyzer from Juchuang not only measures the COD index of water samples, but also supports simultaneous measurement of multiple parameters, such as ammonia nitrogen, total phosphorus, total nitrogen, turbidity, chromaticity, suspended solids, nitrate nitrogen, phosphate, residual chlorine/total chlorine and other indicators of water samples.
The JC-COD-100K handheld COD analyzer from Juchuang does not have digestion function and can be equipped with our company's fast digestion device.

2、 Applicable scopeenclose
It can be widely used in environmental monitoring stations, sewage treatment plants, colleges and universities, research institutes, petrochemicals, papermaking, printing and dyeing, electronics, electricity, steel, agriculture, municipal engineering and other industries.
