|
| |
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 the LabPro. 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 electrodes.
- Most third-party ORP electrodes (with BNC connectors)
Specifications
- Power = 7 mA @ 5VDC
- Input range = –450mV to +1100 mV
- Impedance > 100M Ohm
- Gain: 2.2 V/V
- Offset: 1.20 V (nominal)
