XHCODMn-90B Automatic Permanganate Index Monitor

Product description

      This device is designed based on the sequential injection technique. For this monitoring, national standard method and high-precision injection pump and multiple-way valve are adopted, to sequentially and quantitatively inject the water sample and reagent into the digestion tube for reaction. After reduction by sodium oxalate, the titration end point is determined by back titration, and then the volume of potassium permanganate is measured to calculate the permanganate index (CODMn) of the water sample under test. It is widely used for continuous monitoring of permanganate index of surface waters like river, lake and reservoir

Main Characteristics:


National standard method adopted, and high data reliability, accuracy and
consistency for laboratory data comparison;
Automatically span switching, and being adaptive to the change of actual
water sample concentration;Automatic calibration and cleaning, and thus less maintenance needed;
Measurement data transmitted to the host computer via port RS232 or
RS485, or remotely transmitted by GPRS or other communication modes,
through which real monitoring data can be obtained anytime and anywhere.
Power-off protection, and automatic recovery when powered on;
Data storage, query and export available; built-in data storage, with data
being effectively saved for more than 5 years;
Calibration, quality control, cleaning, and verification with reference
solution in remote manner, greatly reducing operation and maintenance
costs and effectively guaranteeing the accuracy and reliability of data;
Green monitoring for less reagent consumption; spent liquor treated by sort,
resulting to less harmful spent liquor;
Being small in size, light-weight, highly integrated, and convenient to
Corresponding parameter set not found, please add it in property template of background
