The MTC301 series probe is a refillable, combination oxidation reduction potential
(ORP/Redox) probe with a built-in temperature sensor
MTC30103 probe is available with a 1 or 3 m (3.28 or 9.84 ft) cable and is intended for
laboratory use. The probe measures absolute mV values in wastewater, drinking water
and general applications. The probe measures ORP/Redox in wastewater, drinking water
and general applications. A 59 mL bottle of reference electrolyte filling solution (3M KCl
solution saturated with AgCl) is included with the probe.

Set the date and time in the meter before the probe is attached. It is not necessary to recalibrate when moving a calibrated probe from one HQd meter to another if the additional meter is configured to use the same calibration options.
