The electrolyte level in refillable electrodes should be as high as possible and never too far below the fill hole. Hanna electrolytes are standardized by titration with NIST standardized Silver Nitrate solutions. NOTE: Use only HI 7071 and HI 8071 electrolytes containing Silver Chloride (AgCl) with single junction electrodes.
