Safety Information
Precautionary Labels
Read all labels and tags attached to the instrument. Personal injury or damage to the
instrument could occur if not observed. A symbol, if noted on the instrument, will be included
with a danger or caution statement in the manual.
Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after
12 August of 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC),
European electrical equipment users must now return old or end-of life equipment to the Producer for disposal at no
charge to the user.
Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return
end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal.
This is the safety alert symbol. Obey all safety messages that follow this symbol to avoid potential injury. If on the
instrument, refer to the instruction manual for operation or safety information.
Overview
The MTC30101 or MTC30103 is a refillable, combination oxidation reduction potential
(ORP/Redox) electrode with a built-in temperature sensor. The MTC30101 or MTC30103 is
available with a 1 or 3 meter cable and is intended for laboratory use. The electrode provides
ORP/Redox measurements 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 electrode.

For temporary storage, fill the soaker bottle halfway with Hach Electrode Storage Solution or 3M KCl Filling Solution. Loosen the soaker bottle cap and push to install the soaker bottle on the electrode.
- Page 3 Calibration notes • Probes are initially calibrated at the factory. However, regular calibration by the user is recommended for best measurement accuracy. • Additional standards can be selected in the MTC101 Calibration Options. • ZoBell’s redox potential is temperature dependent. The HQd calibration routine factors in this temperature dependency allowing accurate calibrations within the temperature range of 0 - 30 ºC.
- Page 4 Run check standard The run check standard feature validates instrument performance between sample measurements. Use the run check standard feature for periodic or user-defined interval measurement of a traceable standard solution. Set the criteria for check standards from the MTC301 settings menu. Note: Access control must be off or a valid password entered before any of the check standard method options can be changed.
- Page 5 Measurement–Direct Method Before measurement: The electrode must have the correct service-life time stamp. Set the date and time in the meter before attaching the electrode. The electrode is factory calibrated and ready for use. For applications that require greater accuracy and precision, verify the calibration with check standards or perform a user calibration. Routine calibrations are required (Calibration on page Make sure that the platinum electrode is clean before sample measurement...
- Page 6 Measurement - conversion to SHE reference For some applications it is customary to report redox potential readings relative to the standard hydrogen electrode (SHE), also called normal hydrogen electrode (NHE). To do this, select the value in Table 1 Standard potential of reference electrode that corresponds to the temperature of the solution measured.
