    Product description

    The HI4112 lead/sulfate selective electrode is a complete potentiometric cell that contains a silver/silver chloride (Ag/AgCl) reference housed within a PEI plastic body with a potassium nitrate electrolyte. The internal elements are isolated from the sample by a compressed lead sulfide sensing membrane.

    Hanna’s solid-state combination ISEs are designed with a cone style junction. The skirted cone geometry of the sensor forms the liquid junction with the test solution at the tip of the junction cone, producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.

    For the HI4112 to measure lead accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the lead ionic strength adjuster (ISA) solution. The ISA ensures that the activity coefficient is constant so the concentration of free lead ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4112 lead/sulfate solid-state ISE can measure from 1µM (0.21 mg/L) to 0.1M (20,700 mg/L).
