Probe for high-temperature applications IRTD 400

laboratoryindustrialautomatic

Description
The Kaye IRTD-400 is a traceable temperature reference probe used in Kaye validation systems for high-accuracy calibration and verification of temperature sensors. With a wide operating range from -196 to 420 °C and an accuracy of ±0.025 °C over the range, it supports cryogenic, laboratory, industrial and high-temperature calibration tasks.

Applications

• Calibration and verification of RTDs, thermocouples and thermometers
• Temperature validation in pharmaceutical, food, laboratory and industrial environments
• Integration with Kaye automated systems for traceable records and automatic offset calculation

Interface & IRTD Display
The probe integrates with IRTDWin® and the Kaye Console via USB. The calibration interface supports up to two IRTDs and displays temperatures in real time with 0.001 °C resolution. The optional Kaye IRTD Display is a standalone 4.3" touchscreen showing both probe readings and the delta. When used with the Console the interface can be powered by the computer without an external supply.
