Low-Temperature Thermometer: The Robust Secondary SPRT Reference Thermometer for Accurate Temperature Measurements<\/strong><\/p>\n\n\n\n

Our low-temperature SPRT (Standard Platinum Resistance Thermometer) is a calibration standard for precision temperature measurements in the most demanding applications. Designed to meet the needs of research, industry, and quality assurance, these thermometers offer excellent accuracy and reliability. Due to their robustness, they are an attractive alternative to the often very delicate thermometers with quartz protection sheath for everyday measurement work.<\/span><\/p>\n<\/div>\n<\/div>\n\n\n\n

<\/i><\/mark> Protective Gas Filling:<\/strong> The handle of the SPRT is gas-tight, allowing the thermometer to be filled with protective gas. This design shields the thermometer from environmental influences, enhancing its performance, especially at extremely low temperatures. The protective gas filling enables the thermometer to operate at temperatures as low as -200\u00b0C, allowing for calibration down to the argon triple point at approximately -189\u00b0C.<\/span><\/p>\n\n\n\n

<\/i> <\/mark>Temperature Range:<\/strong> With an operating range from -200\u00b0C to 250\u00b0C, our Secondary SPRT Reference Thermometer Model 216 covers a low-temperature range. This makes it a perfect solution for various measurement requirements.<\/span><\/p>\n<\/div>\n\n\n\n

<\/i><\/mark> Small Measurement Uncertainties:<\/strong> The precision of the thermometer is highlighted by its low measurement uncertainties, from just 4.5 mK to 7 mK with a DAkkS accredited calibration according to DIN EN ISO\/IEC 17025. This high accuracy ensures reliable results across all areas of application.<\/p>\n\n\n\n

<\/i><\/mark> Robustness:<\/strong> As a robust alternative to highly sensitive SPRTs (Standard Platinum Resistance Thermometers) with quartz sheath, our secondary SPRT reference thermometers are distinguished by their metal sheath and stable temperature detector. This makes them ideally for long-term use.<\/span><\/p>\n\n\n\n
