Platinum resistance temperature detectors (RTD) are recognized worldwide by metrology laboratories as the most reliable standard for
measuring and comparing temperature information. Platinum provides long-term stability and repeatability for use as a primary standard. It
has a wide useful temperature range which makes it ideal for laboratory and industrial applications.
Wahl accurate, stable platinum sensors are housed in thin wall stainless steel shanks with low mass tips that do not compete with the measured
object. That is why Wahl probes have fast response, and provide an accuracy of ±0.2º at ice point, ±0.5% of reading thereafter.
