Vernier Electrode Amplifier EA-BTA

Use an Electrode Amplifier to collect data from almost any electrode that has a BNC connector. This includes electrodes from Vernier such as our pH electrode, or third-party electrodes, such as pH, ISE (ion-selective electrode), or ORP (oxidation-reduction potential).

The Electrode Amplifier is an ORP/mV/pH amplifier that accepts an electrode with a standard BNC connector. It amplifies a .390 mV to +400 mV range to the 0-5 V range of the Lab Pro

It can be used with any of the following:
  • Vernier Replacement pH Electrode 
  • Most third-party pH electrodes (with BNC connectors) 
  • Other high output impedance eletrodes. 
  • Most third-party ORP electrodes (with BNC connectors) 
  • For LabQuest Mini, NXT Sensor Adapter, LabQuest, SensorDAQ, EasyLink, CBL 2, Go!Link, and LabPro


Specifications
  • Power: 7 mA @ 5VDC
  • Input: range –450 mV to +1100 mV
  • Impedance: 100 MΩ
  • Gain: 2.2 V/V
  • Offset: 1.20 V (nominal)
