In water-treatment applications, temperature measurement, as well as being an intrinsically relevant parameter, is particularly useful because it allows users to compensate for the acquired value of parameters such as pH, chlorine, oxygen, suspended solids and turbidity. SEKO supports operators with our dedicated range of probes for temperature measurement. Temperature is a critical parameter for determining water quality and is of fundamental importance for the environment. It determines the maximum concentration of dissolved oxygen in the water and affects the speed of chemical and biological reactions. Temperature is intrinsically a measure of the thermal state of a material.
