Question
Are there any accuracy specifications for the MTC101/MTC301 probe?
Summary
MTC101/MTC301 ORP Accuracy Specifications
Answer
Accuracy:  ±0.02 mV or 0.05%, whichever is greater. Resolution: ± 0.1 mV (based on meter). The reason that these are not published is because ORP is not used as an absolute measurement, rather a trending measurement. The customer cannot optimize processes based on a single ORP point. They must have multiple ORP points over time to establish trends to control their process. Also, there are many challenges associated with measuring ORP and understanding its influences. It is possible that two ORP probes will not give the same measurement, even in the same samples.
