Scientific Instruments, Inc.

All New For 2016! We proudly introduce – after 40 years of delivering the world's most trusted LNG tank-top LTD systems – the completely reimagined, redesigned, and most advanced solution for LNG tank profiling: The Scientific Instruments Model SI-7000 LTD. Some of the key features include: Level, temperature, and density sensing in a single probe All-stainless construction for superior corrosion resistance in extreme environmental conditions Robust chain drive

Platinum Resistance Thermometers (RTD'S) provide stable output over the range from 60K to 400K.Platinum Resistance Thermometers (PRT’S) provide stable output over the range from 60K to 400K. Units are available in calibrated and uncalibrated versions. Our standard calibration includes the full range from 60K to 400K. Additional information will be available in the near future.

The Scientific Instruments, single-channel Model SCM-10 Temperature Monitor provides the accuracy, resolution, and interface features of a benchtop temperature monitor in an easy to use, easily integrated, compact instrument.The Scientific Instruments, single-channel Model SCM-10 Temperature Monitor provides the accuracy, resolution, and interface features of a benchtop temperature monitor in an easy to use, easily integrated, compact instrument. With appropriate sensors, the Model SCM-10 measures temperature from 1.4 K to 1, 200 K including temperatures in high vacuum and magnetic fields. Alarms, relays, user-configurable analog voltage or current output, and a serial interface are standard features on the SCM-10. It is a good choice for liquefied gas storage and monitoring, cryopump control, cryo-cooler, and materials science applications, and for applications that require greater accuracy than thermocouples allow.

With two or four input channels with ethernet connectivity, these models are the most flexible and accurate temperature monitors currently available.With two, four, or eight input channels with ethernet connectivity, these models are the most flexible and accurate temperature monitors currently available. Virtually any cryogenic temperature sensor from any manufacturer can be selected by a single setting of the front panel. Additional custom or specially calibrated sensors require only a simple setup procedure. In addition to its high accuracyperformance and low noise design, unique features include: Constant voltage AC sensor excitation internal data logging, ethernet connectivity, large easy to read display and extensive utility software.

The Series RO-600 Ruthenium Oxide Sensors are thick film resistors which adhere to a single resistance temperature curve, and have a nominal resistance 1, 000 Ohms at ambient temperature.The Series RO-600 Ruthenium Oxide Sensors are thick film resistors which adhere to a single resistance temperature curve, and have a nominal resistance 1, 000 Ohms at ambient temperature. They offer 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. No orientation dependence of sensor mounting to field direction has been observed. Ruthenium Oxide sensors are available as uncalibrated, grouping, or calibrated units and feature good reproducibility, fast thermal response time and miniature size, all at a reasonable cost. Additional information will be available in the near future.
