Overview

The PASCO family of Ion Selective Electrodes support either point readings or continuous monitoring of specific ion concentrations in water.

A two-meter cable is included.

Advanced Chemistry Procedures Required

PASCO Ion Selective Electrodes are industrial-quality probes that give excellent results when properly used. Operation of these Ion Selective Electrodes assumes training in the safe handling of flammable, caustic and corrosive chemicals and a working knowledge of serial dilution and calibration procedures.

How It Works

Each PASCO Ion Selective Electrode connects to and requires an amplifier/sensor.

Our recommendation is to use them with our Wireless pH sensor

They can also be used with the following older sensors:

*This sensor requires a 550 or 850 Universal interface, legacy 500 or 750 interface or a PASPORT interface with an adapter.
