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.

Overview

The MTC101 series is a non-refillable, gel-filled combination oxidation reduction potential

(ORP/Redox) electrode with a built in temperature sensor. The MTC10101 or MTC10103

electrode is available with a 1 or 3 meter cable and is intended for laboratory use. The

MTC10105, MTC10110, MTC10115 or MTC10130 electrode is available with a 5, 10, 15 or 30

meter cable and is intended for field use. The electrode gives direct measurements of absolute

mV values in wastewater, drinking water and general applications.

Specifications

Specifications are subject to change without notice.

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.
