The HI 4015 and HI 4115 are ion selective electrodes designed for the measurement of Silver/Sulfide ions in aqueous solutions. The HI 4015 is a solid state half-cell sensor that requires a separate reference. The HI 4115 is a combination ion selective electrode.
The document describes the Hanna Instruments HI 4015 solid-state half-cell sensor and the HI 4115 combination ion selective electrode. Both devices are designed for measuring Silver (Ag+) and Sulfide (S2-) ions in aqueous solutions using potentiometric methods. The HI 4015 requires a separate reference electrode, while the HI 4115 incorporates a double junction reference electrode.

You need a Hanna HI 5315 Double Junction Reference Electrode with HI 7072 Fill Solution, a suitable ion or pH/mV meter (like the HI 4222), and a magnetic stirrer.
The difference between two mV values should be approximately 56 ± 4 mV.
The difference between two mV values should be approximately -28 ± 4 mV.
Polish the damaged membrane using the microabrasive strip HI 4000-70 with deionized water.
