Product details
Detailed information on RM-220/RM-430 resistivity monitoring instrument, resistivity measurement and control instrument, and resistivity controller:
RM-220 resistivity monitoring instrument and RM-430 resistivity measurement and control instrument are popular industrial online resistivity monitoring and control instruments with small size and low price. The conductivity cell constant input is manually set using hardware. Adopting simulated temperature compensation. Non isolated current output. Widely used for monitoring and measuring the resistivity of high-purity water, such as RO and pure water manufacturing.
