Myron L ORP Standard Solutions — 80 mV, 260 mV Quinhydrone and 470 mV Light's
Myron L ORP standard solutions for wet calibration of ORP / redox sensors. Two quinhydrone standards (80 mV and 260 mV) and 470 mV Light's solution let you calibrate near the potential your process actually runs at, which matters because ORP accuracy degrades fastest far from the calibration point.
Application
Calibrate the ORP channel on Ultrameter II 6P, Ultrameter III 9P, PoolPro, Ultrapen PT3 and UltrapenX2 PTBT3. Typical uses: verifying sanitizer effectiveness in drinking water and pools, oxidation control in process and cooling water, aquaculture systems, and ORP-based dosing loops in wastewater treatment. Quinhydrone standards are mixed fresh from powder and standard — use them promptly after preparation.
What to order
- 80 mV and 260 mV quinhydrone — 2 oz for single calibrations, multi-pack for shop and route use
- 470 mV Light's solution — stable higher-potential standard, 1 oz
Store pH/ORP sensors in Sensor Storage Solution between uses, and clean platinum ORP electrodes with ORP electrode cleaning paper to keep response times short.
