AmpHel ORP Electrode with Platinum Pin, cloth junction and 5 m cable

The HI 6293005 is an ORP electrode with platinum pin, cloth junction and 5m cable.

Due to the high resistance of the glass membrane, conventional electrodes require a high impedance measurement system. Inadequate insulation of the connectors and cables result in erroneous readings due to leakage or noise. HANNA AmpHel® electrodes incorporate a miniaturised 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. This breakthrough technology provides a stable signal for industrial monitoring as well as a major saving in low noise coaxial cable costs. In some cases, the need for a transmitter is also eliminated, resulting in further cost reductions.

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
