Ion Selective Electrodes

A result of years of research and product development, the Ionode range of Ion Selective Electrodes are the benchmark in price and performance for specialist applications, demanding laboratory environments and OEM solutions. The Ionode range of ISE's include fluoride, chloride, bromide, iodide, cyanide, silver/sulphide and ammonia, all with renowned Ionode performance.

For ion specific measurements of fluoride, cyanide, bromide, iodide, chloride, silver sulphide, ammonia and more, Ionode ISE’s are hand-crafted to the highest possible standards for reliability and accuracy and represent outstanding value for money when compared to equivalent competitors products.
