Middle School Sci w/ Vernier - Electronic

Connect the Ammonium Ion-Selective Electrode BNC to our electrode amplifiers to measure the potential (mV) and calculate the concentration of ammonium (NH4+) ions in aqueous samples.

Description
The Vernier Ammonium Ion-Selective Electrode BNC Connector is a BNC terminated electrode used to measure the concentration of ammonium (NH4+) ions in aqueous samples. Use with Vernier interfaces requires the Electrode Amplifier. Also compatible with Go Direct® Electrode Amplifier.
