Hanna HI1285-5 pH/EC/TDS Multiparameter Probe | 3-in-1 Pre-Amplified Sensor | DIN Connector winemaking electrode Temperature Matters: Allow buffer andThe HI1285 5 is a 3 in 1 pre amplified multiparameter probe that measures pH, EC TDS, and temperature within a single polypropylene body. The pH portion of this probe is constructed with a cloth junction, maintenance free polymer gel electrolyte, and a low temperature glass sensing bulb. The EC TDS portion of this probe utilizes two stainless steel pins for an amperometric determination of conductivity and total dissolved solids. A built in
