Ion Conductivity, pH, ORP Standards for Redox/ORP Electrodes, Orion™
Measure ORP simply and accurately with Thermo Scientific™ Orion™ ORP Standards for Redox/ORP Electrodes. Orion OPR standards are stable for up to a year (unopened) and can be used directly from the bottle with no mixing or diluting. These standards are designed for use with gel-filled ORP/ATC Triode™ electrodes (H260-76MD and H260-76); refillable ORP/ATC Triode electrodes (H260-80MD); glass-bodied ORP electrodes, (H260-44WP and H260-44SC); and Sure-Flow™ ORP electrodes, (H260-42WP and H260-41).
- Does not contain hazardous chemicals
- Included in the new ASTM ORP method
- Used as relative mV standard to calibrate the offset of sample
- +220mV vs. Ag/AgCl using 4M KCl saturated with AgCl filling solution (Part No. H258-5), +420mV vs. Standard Hydrogen Electrode (EH)
