Ion-Selective Electrodes

Our Go Direct family of Ion-Selective Electrodes are great for monitoring five environmentally-important ions: calcium (Ca2+), chloride (Cl), ammonium (NH4+), nitrate (NO3), and potassium (K+). They connect via Bluetooth® wireless technology or wired via USB to your device.

ISE Modules and Standards

Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results. They are not recommended for middle school or elementary students.

ISE Replacement Modules are available for Ammonium, Calcium, Nitrate, and Potassium Ion-Selective Electrodes. Chloride does not need a replacement module.

Important: We recommend that you do not purchase ISE replacement modules too far in advance of their expected time of use; degradation occurs while replacement modules are stored on the shelf.
