HK-368 Inductive Concentration/Conductivity Analyzer is an online industrial analyzer. The sensor adopts corrosion-resistant material and contact-free detection mode, which can effectively prevent the sensor from being corroded, polluted and polarized effect by the corrosive medium. There are many installation method, which can be suitable for different occasions. The measuring medium can be switched, which is easy to use. It is mainly used to monitor the regenerated solution concentration of ion exchanger in the process of producing high-purity water by ion exchange. It can be widely used in power, chemical industry and seawater to continuously measure the low-concentration acid/alkali/salt.
◆ Adopts corrosion-resistant materials, which can prevent thepolarization, scaling problems.
◆ Therange of conductivity is0—2000 mS/cm, the sensor does not need to be replaced.
◆ It can measure conductivity,concentration (NaOH, NaCl, HCl andH2SO4), salinity and TDS.
◆ Chinese or English menu, and easy to set the parameters.
◆ The color LCD screen can display the measured value, sample temperature and measuring medium, the content is rich and easy to understand.
◆ 100,000 measurement data can be saved, which is convenient to view.
◆ Two current outputs (4-20mA) and four alarm signals.
◆ Communication:RS485/PROFIBUS-DP/HART, choose one.
◆ Flange installation method or flow cell installation method is selected for different site environment.
