New Design: Gas-Tight Handle with Protective Gas Filling<\/strong><\/h4>\n\n\n\n

Thanks to the new design of the gas-tight handle, the protective tube of the low-temperature precision thermometer can be filled with a protective gas. This improves the thermometer’s properties and extends its temperature range down to extremely low -200 \u00b0C. Thus, the low-temperature precision thermometer can be calibrated down to the argon triple point at approximately -189 \u00b0C.<\/p>\n<\/div>\n<\/div>\n\n\n\n

DAkkS Calibration at Temperature Fixed Points<\/h3>\n\n\n\n

Low-temperature precision thermometers can be calibrated in our own DAkkS calibration laboratory<\/a>. DAkkS accreditation ensures that all calibrations are traceable to national and international standards.<\/p>\n\n\n\n

The low-temperature precision thermometers have been designed to be highly suitable for calibration at temperature fixed points down to the argon triple point. The measurement uncertainty is calculated from many components. The largest contributions to the measurement uncertainty budget are the thermometer’s reproducibility, ITS-90 deviation function, self-heating, and hysteresis of the temperature sensor. With the parameters from the calibration certificate, the low-temperature precision thermometer can be used with the respective deviation function in the temperature range of -189 \u00b0C to 232 \u00b0C.<\/p>\n\n\n\n
