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.
