CTE™ Field ΔT Severity Calculator
Uses the official CTE™ severity chart (based on raw ΔT). Enter up to three reference readings—your baseline is the average.
Blank fields are ignored. Average is calculated from the values you enter.
Recorded in report for transparency. Does not change severity math.
Surface match (increases confidence):
Calculate is locked until required guardrails are confirmed.
These guardrails improve accuracy and strengthen documentation; they do not change the CTE™ severity math.
- Set emissivity correctly before measuring. Wrong ε can distort displayed temperatures.
- Use the same settings for hotspot and reference points to keep ΔT meaningful.
- Use 2–3 reference points to reduce noise; blank fields are ignored.
- Severity is evaluated using ΔT in °F per the official CTE™ chart (°C is converted automatically).
- Severity indicates priority, not failure. Document, trend, and investigate as appropriate.
