Reference probes
Digital Display Unit

The IRTD is a high accuracy traceable temperature standard probe used as part of the Lives International validation systems for calibrating sensors. During sensor calibration / verifications, sensors are compared against the IRTD and offsets are automatically calculated and stored. The broad temperature range from  -196 to 420°C, enables it to be used in virtually all temperature validation applications.

Temperature Reference Standard

The IRTD is an integral part of Lives International’s automated sensor calibration system and communicates directly with all Lives International systems. With an accuracy of +/- 0.025, the IRTD temperature standard probe provides a 4 to 1 ratio for calibrating sensors to 0.100°C.  With this accuracy this temperature reference standard is one of the most accurate industrial temperature reference standards in the market.

The temperature reference standard probe can be used for confirming the accuracy of other temperature devices. For this purpose, Lives International has developed XpertLog® software. The XpertLog® software is one convenient interface screen lets you track probe stability, numerically and graphically, and confirm system accuracy.

See real time data of your IRTD using the calibration interface and the XpertRTD display interface. The calibration interface connects directly to your computer using USB and to up to two IRTDs. The software immediate shows the temperature of the IRTDs with an accurate resolution to the thousandths degree. The interface is simple, easy to use, and does not need a power source, as it is powered by the computer.

The XpertRTD Display is a standalone interface. This advanced display unit seamlessly connects with up to two Lives International Reference probes, offering real-time temperature data in a user-friendly format. Equipped with a 4.3″ touch screen, the XpertRTD Display provides clear and intuitive readings for both IRTDs, allowing users to monitor temperature with ease. The display also showcases the temperature difference (Delta) between the two connected IRTDs, enabling quick and accurate analysis. Supporting both types of IRTD Connector cables, this versatile unit ensures compatibility with your preferred setup.
