The Fluke-720RTD temperature probe is for use with Fluke 721 precision pressure calibrators and Fluke 719Pro electric pressure calibrators. The 720RTD has a 10 inch (254mm) insertion depth with inch (6.3mm) diameter stainless steel sheath. If a Fluke 721 precision pressure calibrator is used with the Fluke 720RTD probe then it is not necessary to set the probe type. The user simply connects probe to calibrator and configures the display to read Temperature. The display shows 'OL' when the measured temperature is outside the nominal measurement range of the RTD function (below -40°C or above 150°C).

Need to calibrate your pressure measuring device? This RTD-type temperature probe from FLUKE is hot stuff. It offers plug-and-play functionality with pressure calibrators in the 719 and 721 series, so there's no need to manually set the probe type. Simply connect the handy gadget to the reader, configure the display to temperature and you're good to go. Thanks to an accuracy of +0.25°C and a pin-sharp resolution of 0.01°C, you can be sure of the highest levels of precision in your results.

• Spiral cable design for flexible movement
• Stainless steel probe sheath is resistant to corrosion and wear for a long service life
• Insertion depth of 254mm helps minimise conduction errors
• Wide temperature measurement range between -40°C and +150°C for use in demanding environments

• Heating system maintenance
• Scientific laboratories
• Industrial processes

An RTD (resistance temperature detector) sensor uses changes in resistance to calculate temperature. Resistance increases as you turn up the heat, so you can calculate temperature by measuring fluctuations in the sensor's electrical resistance.
