Silver sulphide half cell hanna hi4015

Description

Silver sulphide half cell hanna hi4015 

The HI-4015 silver/sulphide selective electrode is a potentiometric half-cell sensor housed within an epoxy body. The internal elements are isolated from the sample by a compressed silver/silver sulphide sensing membrane. This solid state sensor requires a separate reference electrode to complete the measurement system.

Hanna’s solid state half-cell ISEs are designed for use with the HI-5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the reference 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.

Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4015 silver/sulphide solid state ISE can measure silver from 1µM (0.11 mg/L) to 1M (107,900 mg/L) and sulphide from 0.1µM (0.003 mg/L) to 1M (32,100 mg/L).
