Ohaus pH Electrode KCl Solution & DO Zero Oxygen Powder

Ohaus pH Electrode KCl Solution & DO Zero Oxygen Powder

Ohaus pH Electrode KCl Solutions and DO Zero Oxygen Powder provide essential maintenance chemicals for preserving electrode performance, ensuring accurate measurements, and supporting routine calibration procedures across pH, reference, and dissolved oxygen electrodes.

The Reference Electrolyte (3M KCl saturated with AgCl, 30ml) serves as refilling solution for Ag/AgCl single junction electrodes, replenishing the internal electrolyte when levels drop below the recommended 2cm above the measurement solution level to maintain stable reference potential and prevent measurement drift. 

The pH Electrode Protection/Storage Solution (3M KCl, 125ml) keeps pH electrodes properly hydrated during storage and between measurements, preventing the glass bulb and reference junction from drying out which would cause slow response, calibration failure, and inaccurate readings—critical since pH electrodes should never be stored in distilled or deionized water as this causes ions to leak from the glass bulb and reference electrolyte. 

The DO Zero Oxygen Powder enables zero-point calibration of dissolved oxygen electrodes by creating an oxygen-free solution when dissolved in water, providing the 0% oxygen reference point essential for accurate DO measurements alongside atmospheric saturation calibration at 100% oxygen. Proper electrode maintenance using these solutions extends electrode life, reduces calibration issues, maintains measurement accuracy, and supports compliance with good laboratory practices by ensuring electrodes remain in optimal condition for reliable pH, ORP, and dissolved oxygen measurements across water quality testing, environmental monitoring, aquaculture, food and beverage production, pharmaceutical applications, and research laboratories requiring traceable, accurate electrochemistry measurements.
