Facilities

We maintain measurement quality control (QC) via our instrumentation and temperature calibration facility. This consists of four automated computer interfaced precision temperature baths with laboratory data logger for multiple sensor/instrument calibrations over ambient temperatures to sub-milliKelvin (mK) resolution and within 0.01K nominal accuracy. To achieve the latter we have an NBS traceable platinum resistance thermometer, NBS traceable high stability precision thermistor standard, an HP quartz thermometer, and Julie ppm level resistance standards. We have software for generating calibration coefficients, residuals, and for curve fitting to standard equations and statistical analysis. We routinely employ thermal conductivity and precision resistance standards during all field operations
