Model RO-600(1K) – Ruthenium Oxide RTD – RuO Thermometer from Scientific Instruments

The Model RO-600 Ruthenium Oxide Temperature Sensors are thick film resistors which adhere to are available with calibration down to 20mK or grouped/interchangeable and have a nominal resistance of 1,000? at ambient temperature. The ruthenium oxide temperature sensor offers excellent performance characteristics in magnetic field environments. These sensors exhibit an initial small negative magnetoresistance at temperatures below 250 mK at low fields (less than about 1.5 Tesla). The magnetoresistance then becomes positive at larger fields and increases at lower temperatures. This magnetoresistance is repeatable. For example, a resistance change of 8% induced by an 8 Tesla field at a temperature of 80 mK corresponds to a temperature error of 7 mK.

Model SI-435 Silicon Diode Temperature Sensors

Si-435 Silicon Diodes from Scientific Instruments offer the industry’s highest 4K accuracy in an interchangeable/uncalibrated diode temperature sensor. The CAP package is the smallest encapsulated diode mount on the market while the SMD package offers the utility of a compact surface mount. Individually calibrated options are available where millikelvin accuracy is required.
