Pratt & Whitney Measurement Systems, Inc. Environmental Data Logger U308432

Benefits Record environmental data Evaluate your Constant Temperature Room - Check air temperature regulation - Check air temperature uniformity Evaluate thermal soaking - Check temperature difference between master and artifact. - Determine thermal time constants for masters and artifacts. - Check master and artifact temperature stability. Evaluate instrument stability - Measure instrument zero drift in your measurement environment. - Calculate laser scale factor change based on air temperature, pressure, and humidity changes. Calibrate your laser based instrument Set the instrument scale factor based on air temperature, pressure, and humidity values. Determine the calibration interval Set a reference point immediately after setting the second point of a two point calibration. Track parts per million (ppm) changes since calibration to determine if a new calibration is required. Determine correction factors Set a reference point immediately after setting the second point of a two point calibration. At measurement time, record the parts per million (ppm) changes since calibration multiplied by the artifact length to determine a measurement correction factor.
