Hach Intellical MTC101 Laboratory Low Maintenance Gel Filled ORP/RedOx Electrode, 1 m Cable
Intellical MTC101 Laboratory Low Maintenance Gel Filled ORP/RedOx Electrode, 1 m Cable
Intellical MTC101 is a digital, combination oxidation reduction potential (ORP/Redox) probe with a non-refillable, gel-electrolyte reference and built-in temperature sensor. MTC101 has low maintenance needs thanks to a non-refillable gel-filled single open reference junction. The laboratory version of this metallic electrode is shockproof with its epoxy plastic body protecting down to the platinum sensing element. The Electrode is available with a 3 or 1 m cable. The MTC101 electrode is ideal for measuring ORP/RedOx absolute mV values in wastewater, drinking water and aqueous media applications. The MTC101 is not suitable for use with organic solvents.
Benefits
Provides fast, stable response in a variety of applications
Intellical digital probes lock on the result when the measurement is stable, removing the guesswork in having a moving number. Additionally, the probe’s large open reference junction provides maximum surface area between sample and reference electrolyte for fast measurement stability.
Ultimate traceability in measurement history
Stored time and date stamp for each measurement, operator and sample ID, calibration history, parameter, and probe serial number
User alerted when re-calibration is needed
No guesswork needed to provide most reliable and accurate results with each measurement.
Can be moved between meters without the need to re-calibrate or re-enter measurement settings
Ideal for a multi-user environment with multiple HQD series Laboratory and Portable meters
