The redox potential (ORP, mV) measurements may be made with the meters equipped with the mV measuring function. All ELMETRON's pH meters and multifunction meters have this function.

CPR-411 used for simultaneous pH, mV (redox potential) and temperature measurements.

• Simple field and laboratory meter.
• Used for simultaneous pH, mV (redox potential) and temperature measurements.
• The meter may be used for measurements in swimming pools.
• Easy in use.
• Calibration of the pH electrodein 1, 2 or 3 points. (pH: 4.00, 7.00, 9.00 or 4.00, 7.00, 10.00).
• The model is equipped with separate BNC-50 connectors for pH and redox electrodes, what enables simultaneous meassurement of this parameters.
• Memory of 50 results.
• No PC connection.
