The Hanna HI 4008 and HI 4108 are ion selective electrodes designed for the measurement of cupric ions in aqueous solutions. The HI 4008 is a solid state half-cell sensor that requires a separate reference. The HI 4108 is a combination ion selective electrode.
The Hanna Instruments HI 4008 and HI 4108 are ion selective electrodes designed for the measurement of cupric ions in aqueous solutions. The HI 4008 is a solid state half-cell sensor that requires a separate reference electrode, while the HI 4108 is a combination ion selective electrode that incorporates a reference electrode. Both utilize a cupric sulfide/silver sulfide membrane to detect free cupric ions.

The HI 4008 requires a Hanna HI 5315 Double Junction Reference Electrode with HI 7072 Fill Solution and a suitable ion or pH/mV meter.
Fill solution should be added daily to the electrolyte reservoir before electrode use.
