HI 2221 and HI 2223 are able to detect if the calibration buffer solution is contaminated or if the temperature is outside the defined range. When a pH electrode is dirty, it has a slow response time & unstable reading. HI 2221 and HI 2223 warns the user in the event the electrode is dirty. See www.hannainst.com for more information.
