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) serves as a robust calibration standard for the most demanding applications in precision temperature measurement. Developed to meet the needs of research, industry, and quality assurance, these thermometers offer outstanding accuracy and reliability. Thanks to their robustness, they are an attractive alternative for everyday measurement work to the often very sensitive thermometers with a quartz protective tube. <\/span><\/p>\n<\/div>\n<\/div>\n\n\n\n

<\/i><\/mark> Protective gas fill:<\/strong> The SPRT handle is gas-tight, allowing the thermometer to be filled with protective gas. This design protects the thermometer from environmental influences and thus improves its performance, especially at extremely low temperatures. The protective gas fill enables use of the thermometer at temperatures down to -200 \u00b0C, allowing calibration down to the argon triple point at approx. -189 \u00b0C.<\/span> <\/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 the low-temperature range. This makes it a versatile solution for a wide variety of measurement requirements. <\/span><\/p>\n<\/div>\n\n\n\n

<\/i><\/mark> Low measurement uncertainty:<\/strong> The thermometer\u2019s precision is underscored by its low measurement uncertainties of just 4.5 mK to 7 mK with a DAkkS-accredited calibration to DIN EN ISO\/IEC 17025. This high accuracy ensures reliable results across all operating ranges. <\/span><\/p>\n\n\n\n

<\/i><\/mark> Robustness:<\/strong> As a robust alternative to very sensitive SPRTs with a quartz sheath, our secondary SPRT reference thermometer stands out with its metal sheath and stable sensing resistors. This makes it ideal for long-term use. <\/span><\/p>\n\n\n\n
