Hanna Instruments-6493005 AmpHel® ORP Electrode with Replaceable Battery

Sale price£376.43
Stock: In stock

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.





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


The HI 6493005 is an amplified ORP electrode with gold pin, cloth junction and a 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.
