Everythingdrifts.I keep it true.
Metrology, calibration and the systems behind trustworthy measurements, with temperature as the worked example, plus AI that helps and still shows its work.

Five places to start. Everything runs in your browser; nothing you type is sent anywhere.
Temperature
RTDs and thermocouples side by side: specifications, accuracy with and without coefficients, how each is calibrated, and 2nd, 3rd or 4th degree curve fits.
Open → 02More measurements
Humidity, pressure, voltage, current, resistance, conductivity, mass, length and torque, each with instruments, standards, calibration steps and calculators.
Open → 03Calculators
Calibration interval from drift, pass or fail with guard bands, and an uncertainty budget you can fill in with your own numbers.
Open → 04AI for the lab
A certificate reader that shows its work, a prompt library, and a control chart that writes the AI prompt for you.

Calibration and interval analysis
Setting intervals from each instrument's own history rather than a fixed calendar, so there are fewer needless calibrations and earlier warning when something drifts.
Equipment asset management
One trustworthy record for every instrument: where it is, what it measures, when it was last checked and what was found.
Standards and compliance
Working within ISO/IEC 17025 ISO 10012 ANSI/NCSL Z540 and keeping the records easy to audit.
Temperature calibration
RTDs and thermocouples of every common type, from comparison and fixed-point calibration to the calibration curve and its uncertainty.
Applied AI for metrology
Language models and data tools for reading certificates, spotting trends and drafting routine documents, always with a person checking what matters.
