Abstract

A potentiometric electrode having an ion selective half cell containing a non-reactive lead such as platinum in contact with an electrolyte containing a reversible redox couple having a large exchange current and a substantially flat temperature coefficient of potential such as 5 molar iodide, 3.times.10.sup.-2 molar triiodide, thereby having an electrode with a rapid and reproducible temperature response.
