HI-2931B/5 AmpHel® ORP Electrode with Internal Battery
HI-2931B/5
Hanna AmpHel® electrodes incorporate a miniaturized amplifier which resolves most of the problems associated with high impedance signals. The amplifier circuitry is located right on top of the electrode and is completely sealed. As a result, a strong, low impedance signal is emitted and ordinary connectors with long unshielded cables can be used.
The HI-2931B/5 is an ORP electrode with platinum pin, PTFE junction and 5m cable.
Key features
- Strong signal up to 75 metres
- Low noise coaxial cables are no longer required
- Measurements in unclean samples and high humidity conditions
- Models with external replaceable battery, for longer electrode life
- Glass sensor for specific applications
BNC Connection – BNC is one of the most commonly used connector types in pH meters and electrodes. Compatible with any meter or electrode that uses BNC connectors.
