Vernier® Electrode Amplifier

The Electrode Amplifier is an ORP/mV/pH amplifier that accepts an electrode with a standard BNC connector. It amplifies a –450 mV to +1100 mV range to the 0 - 5 V range of our interfaces.

• Power: 7 mA at 5 VDC
• Input range: –450 mV to +1100 mV
• Impedance: >100 MΩ
• Gain: 2.2 V/V and offset: 1.20 V (nominal)

The electrode amplifier is an ORP/mV/pH amplifier that accepts an electrode with a standard BNC connector. It amplifies a -450 mV to +1100 mV range to the 0-5 V range of our interfaces. It can be used with any of the following: replacement pH electrode, most third-party pH electrodes (with BNC connectors), other high output impedance eletrodes. Most third-party ORP electrodes (with BNC connectors).
