Overview
HK-368 acid-base concentration meter/conductivity meter
Product Details
The HK-368 acid-base concentration meter/conductivity meter is an online industrial analytical instrument. The sensor is made of corrosion-resistant materials and adopts a non-contact detection method. Effectively prevent corrosion, contamination, and polarization effects of highly corrosive media on electrodes. There are multiple installation methods to choose from, suitable for different occasions. Users can freely switch the measurement medium, making it easy to use. It is mainly used to monitor the concentration of the regeneration solution of the ion exchanger in the process of producing high-purity water by ion exchange method, and is an instrument for producing high-purity water by ion exchange method. It can be widely used for continuous measurement of low concentration acid-base salt solutions in power, chemical, and seawater industries.
◆Using corrosion-resistant materials, there are no issues such as polarization or scaling
◆Conductivity range0—2000mS/cm， No need to replace electrodes for full range
◆Measurable conductivity and concentration(NaOH，NaCl, HCl, and H2SO4), salinity, and total dissolved solids
◆The user menu can choose between Chinese and English, and the parameter settings are simple and convenient
◆The color LCD screen displays measurement values, sample water temperature, and measurement medium, with rich content and easy understanding
◆Can be saved100000 measurement data, convenient for users to view
◆two-way4-20mA circuit output and four-way alarm signal
◆RS485/PROFIBUS-DP/HART communication protocol can be selected from three options
◆Optional flange and flow pool installation methods, suitable for different on-site environments
