MR composite electrode 5503/ORP measurement range: 1500mV
Operating temperature: 0-80℃
Material Science: PPS (polyphenylene sulfide) shell

Four electrode measurement system integrated (measuring electrode, reference electrode, grounding electrode, temperature electrode); Circular tetrafluoroethylene liquid interface, dual liquid reference electrode, effectively extending electrode life; PPS (polyphenylene sulfide) shell, capable of withstanding high temperatures and corrosion resistance; Gel electrolyte, no need to supplement KCl solution
characteristic
1. 2-wire ORP transmitter with microprocessor included: input/output insulation, digital display.
2. Automatically determine whether the electrode performance is good: Determine whether the electrode is good based on the electrode characteristics calibrated with standard solution. And display Good, Low, High on the monitor to indicate the difference between the potential of the standard solution and the potential measured by the electrode.
3. The output range can be changed.
4. Temperature measurement and display: with temperature compensation function.
5. Maintain output during maintenance.
Select function
