Precision Thermometers
Resistance Thermometers and Thermocouples
eXacal precision thermometers are used for precise temperature measurements or as calibration standards. They have been continuously optimized over many years in our thermometer manufacturing facility to ensure the highest measurement accuracy. The various eXacal thermometers can be versatilely used in a temperature range from -200 °C to 1200 °C.
Our eXacal resistance thermometers are a robust alternative to the extremely sensitive ITS-90 Standard Platinum Resistance Thermometers (SPRTs). The eXacal thermocouples, made of platinum, are available with or without a stainless steel reference junction.

Standard Platinum Resistance Thermometers (SPRT)
Robust Secondary SPRT Reference Thermometer for Highly Accurate Temperature Measurements
Our SPRTs (Standard Platinum Resistance Thermometers) serve as calibration standards in precision temperature measurement and for accurate temperature measurement in demanding applications. Developed to meet the needs of research, industry, and quality assurance, these thermometers offer excellent accuracy and reliability. The SPRTs (Standard Platinum Resistance Thermometers) comply with the requirements of ITS-90.

Precision Thermometers
Our precision thermometers are ideal as temperature standards for calibrations or for accurate temperature measurements. Available as resistance thermometers (Pt100) and as noble metal thermocouples of types R/S/B, Pt/Pd, and Pt/Au. Our eXacal resistance thermometers are a robust alternative to the extremely sensitive ITS-90 Standard Platinum Resistance Thermometers (SPRTs). The eXacal thermocouples are manufactured with a stainless steel reference junction.
Models:

Noble Metal Thermocouples
Industrial Reference Thermometers
Industrial Reference Thermometers (Pt100 and noble metal thermocouples) are perfect for industrial use in traceable temperature measurements or as secondary standards in industrial calibrations (for example, in a temperature block calibrator).
Thermometers for Special Applications
Special designs: We also manufacture precision thermometers according to your individual requirements, for example, differential thermometers, angled temperature sensors, and thermometers according to specific customer requests.
Immersion Thermometers
eXacal immersion thermometers (platinum resistance thermometers) are temperature sensors designed for extreme environments where both the transition point and the leads must withstand temperatures across the entire temperature range of the temperature sensor. These immersion thermometers can be used in various applications, including the calibration of sensors in laboratory chillers, autoclaves, ovens, stability test chambers, and incubators. They can be fully immersed in liquids or dry media.
Thermometer Manufacturing – Handcrafted Precision Thermometers
Our eXacal precision thermometers are handcrafted in our manufacturing facility in Fulda, Germany. They are specifically designed for precise temperature measurements in the range of -200 °C to 1200 °C. Our expertise extends beyond the product: we also develop specialized tools and manufacturing processes. From design to the final accredited calibration according to DIN EN ISO/IEC 17025 (DAkkS), we are completely independent of external suppliers, thereby ensuring the high quality of our thermometers.
Calibration of eXacal Thermometers
eXacal thermometers are calibrated in our own
DAkkS calibration laboratory.
The calibration of eXacal precision thermometers is performed at ITS-90 temperature fixed points in the range from the argon triple point to the silver freezing point with excellent measurement uncertainties.
Alternatively, eXacal thermometers can also be calibrated using the comparison method.
eXacal Technology
The eXacal precision thermometers have been completely redeveloped from the ground up. Every component has been designed with the utmost care and perfectly matched to the others.
A central highlight is the innovative handle, which serves as a central technology carrier. Thanks to its modular design, it allows for diverse combinations of eXacal thermometers.
