Temperature probes

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.

One of the most commonly used methods to determine temperature is measurement via a resistance thermometer. Resistance thermometers offer great stability, accuracy and repeatability while the advantages of platinum resistance thermometers include high precision and a wide operating range. The electrical resistance of the sensor used in this type of thermometer, called RTD, changes as the temperature varies; rising in line with temperature increase and for this reason it is defined as PTC (Positive Temperature Coefficient). The measurement of the electrical resistance value therefore allows the user to determine the temperature under examination.
