Platinum resistance temperature detectors (RTD’s) 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. 
Our accurate, stable platinum sensors are housed in thin wall stainless steel shanks with low mass tips that don’t compete with the measured object. That’s why Wahl probes have fast response, and provide an accuracy of ±0.2°F at ice point, ±0.5% of reading thereafter.
Every probe is engineered to do a specific job in measuring surfaces, liquids, semi-solids or gasses. Each probe has a high quality, heatresistant Delrin handle, a coiled 5-foot cord and a snap-in connector that mates it solidly to our thermometer
