Resistance thermometers and thermocouples

eXacal precision thermometers are used for precise temperature measurements or as calibration standards. They have been continuously optimised over many years in our thermometer manufactory to ensure the highest measurement accuracy. The range of eXacal thermometers is wide and can be used in a temperature range of -200 °C to 1200 °C. Our resistance thermometers offer a robust alternative to the extremely fragile ITS-90 standard thermometers. The eXacal thermocouples, made of platinum, are available with or without stainless steel reference junction.

Product highlights

Our key thermometers are used both for precise temperature measurement and as reference thermometers when calibrating other thermometers.

Standard platinum resistance thermometer (SPRT)

Robust secondary SPRT reference thermometer for the most accurate temperature measurements

Our SPRT (standard platinum resistance thermometers) are used in precision temperature measurement as a calibration standard and for accurate temperature measurement in demanding applications. Designed to meet the needs of research, industry and quality assurance, these thermometers offer outstanding accuracy and reliability. The SPRT (standard platinum resistance thermometers) meet the requirements of the ITS-90.

Secondary SPRT reference thermometer (-200 °C to 250 °C)

Precision thermometer

Precision thermometer: Perfect as a temperature standard for calibrations or for precise temperature measurements. Available both as resistance thermometers (Pt100) and as noble metal thermocouples of types R/S/B, Pt/Pd and Pt/Au.

Industrial reference thermometers

Industrial reference thermometers (Pt100 and noble metal thermocouples): Perfectly designed for industrial use in traceable temperature measurements or as secondary standards in industrial calibrations, for example in a temperature dry block calibrator.

Thermometers for special applications

Special designs: We also manufacture precision thermometers to individual customer requirements, including difference thermometers, angled temperature probes and thermometers to special customer specifications.

Immersion thermometers

The eXacal immersion thermometers (platinum resistance thermometers) are temperature sensors designed for extreme environments where both the junction and leads must withstand temperatures throughout the temperature range of the temperature sensor. These immersion thermometers can be used in various applications including the calibration of sensors in laboratory coolers, autoclaves, ovens, stability test chambers and incubators. They can be fully immersed in liquids or dry media.

Thermometer Manufacture – Precision thermometers made by hand

Our eXacal precision thermometers are handmade in our manufactory in Fulda, Germany. They are specially designed for precise temperature measurements in the range from -200°C to 1200°C. Our expertise goes beyond the product: we also develop specialised tools and manufacturing processes. From design to final DAkkS calibration, we are completely independent of external suppliers, which ensures the high quality of our thermometers.

Calibration of eXacal thermometers

eXacal thermometers are calibrated in our own DAkkS calibration laboratory.

The calibration of the eXacal precision thermometers is done at ITS-90 temperature fixed points in the range from the argon triple point to the silver freezing point with excellent measurement uncertainties.

Alternatively, the eXacal thermometers can also be calibrated using the comparison method.

eXacal technology

The eXacal precision thermometers have been developed from scratch. Each component has been designed with the greatest care and perfectly matched to the others.

A central highlight is the innovative handle, which serves as the central technology carrier. Thanks to its modular design, it allows combinations of the eXacal thermometers in many different ways.
