MemoRail is the first genuinely compact, digital analyzer for measuring pH values, ORP, conductivity, oxygen and temperature with Memosens sensors. Two analog active / passive 4 to 20 mA outputs supply the measured values for the process value and temperature to the process control system or a PLC. MemoRail is immediately ready for measurement on connecting a precalibrated Memosens sensor. “Used” sensors can simply be replaced. The highly space-saving modular housing of the MemoRail devices is only 12.5 mm wide.
