  • 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.



  • Customizable Display – display any combination of the following outputs

  - Material temperature (3 sensors)   - Air temperature   - Air pressure   - Humidity   - GageCal position   - Laser Factor

  • English/Metric operation – select with the E/M button
  • Data Logging

  - Log displayed output values at a predefined (1 second or larger) interval.   - Displayed values are date and time stamped and added to a CSV (comma separated values) data file.   - CSV files can be viewed in Excel or in the chart viewer.

  • Chart Display

  - Shows present or archived logged data in chart format
  - Charts automatically scale to fit the adjustable window size.   - A “zoom” feature allows you to zoom in on chart areas of interest.    - A “save” button allows you to save the chart in a variety of formats (.png, .pdf …). 

  • Sensor Calibration – Enter a calibration factor for each sensor.  The calibration correction value is stored and displayed in the software.
  • PPM Mode – Set a material and laser reference point and display deviations from the reference point in parts per million (microns per meter or millionths per inch).
  • Customizable sensor names – change the sensor names that are displayed in the software and in the charts by modifying the name values in the Logger.ini file.
