The HI 4007 and HI 4107 are ion selective electrodes designed for the measurement of chloride ions in aqueous solutions.
The Hanna Instruments HI 4007 and HI 4107 are ion selective electrodes designed for the measurement of chloride ions in aqueous solutions. The HI 4007 is a solid state half-cell sensor that requires a separate reference, while the HI 4107 is a combination ion selective electrode with an incorporated reference electrode. Both devices function as potentiometric sensors for determining free chloride ions in ground water, boiler water, and drinking water.
