Surface Temperature Sensor Calibration: In Situ Technique
S P Schumann · 1985
The surface temperature dectors on a guarded hot plate can be calibrated in place using differential thermopiles. A ten-junction Type T thermopile was used to calibrate a 1.22-m (4-ft) guarded hot plate using water triple point cells as the reference temperature. The stability and precision of these thermopiles, over a year's span, was on the order of 20 to 30 millidegrees.
