The 315P Ion Specific Electrode Meters offer expanded benchtop features through patented polymer electrode technology, three-in-one gel-filled electrodes, and microprocessor design. Our exclusive design includes an ultrasonically sealed case and special electrode connectors to ensure that the ion specific electrode meters have an IP67 rating (dust-tight and waterproof to a depth of one meter (3.3 feet)). In addition, the 315P Ion Specific Electrode Meter allows you to set a calibration reminder interval, date and time, manual temperature compensation, and pH calibration points. Up to 800 endpoint results can also be stored in the ion specific electrode meter's memory. The 315P Ion Specific Electrode Meters also allows you to have ISE capabilities. The ion specific electrode meters display temperature and either pH, mV, or mg/l on a large 5 digit LCD screen. The ion specific electrode meter uses its autoread function to check the stability of the pH measurement signal so that good measurements can be taken. For the best results pH measurements should be temperature corrected and the 315P Ion Specific Electrode Meters are designed to be used with an external temperature probe; however the ion specific electrode meters also have a manual temperature adjustment feature if an external temperature reference isn't available. During calibration the ion specific meters automatically recognize standard buffer solutions. The ion specific electrode allows for either two or three point calibration of ion specific electrodes (ISE).

Exclusive electrode socket covers allow meters to be IP67 waterproof with any BNC electrode and/or temperature probe.
