I. I. I. I. I. Introduction: Introduction: Introduction: Introduction: Introduction:
The Hanna HI 4011 and HI 4111 are ion selective elec-
trodes designed for the measurement of Iodide ions in
aqueous solutions. The HI 4011 is a solid state half-cell
sensor that requires a separate reference. The HI 4111 is a
combination ion selective electrode.
