Metrology mastery, built for the way you study
An AI tutor that answers from real measurement standards — ready whenever you are, at a price made for students.
For college and university students entering measurement science
If you’re in a metrology, precision-manufacturing, quality, or engineering-technology program, the Student Plan is your around-the-clock study partner. It explains the concepts your coursework assumes, walks you through the calculations step by step, and gets you ready for the ASQ Certified Calibration Technician exam — all grounded in the same standards the profession runs on.
One tutor, four learning modes
Switch between modes depending on what you need — understand an idea, grind through a problem, prep for the exam, or find the right clause in a standard.
Concept
Clear, patient explanations of the fundamentals — measurement traceability, uncertainty, ISO/IEC 17025, the SI units, and core calibration principles — pitched to your level.
Problems
Numerical problems worked through one step at a time — uncertainty budgets, Test Uncertainty Ratio (TUR), and unit conversions — so you learn the method, not just the answer.
Exam Prep
Prepare for the ASQ Certified Calibration Technician (CCT) exam with practice questions, Body-of-Knowledge-aligned drills, and a 110-question mock exam — each with detailed explanations.
Documents
Use Document Navigator to ask about the standards directly — locate and understand ISO/IEC 17025:2017 clauses and the NIST GUM, with answers tied to the source text.
Built to make studying actually stick
Grounded, not guessed
Answers are drawn from the MetLibrary knowledge base of recognized metrology standards — not improvised — so what you learn matches the real thing.
Available 24/7
Study on your schedule, the night before a lab or the week before an exam. No appointments, no waiting on office hours.
Exam-ready
Unlimited daily quizzes, BoK-aligned drills, and a full 110-question CCT mock exam with explanations help you walk in prepared.
Made for student budgets
Full Student access for $9/mo with .edu verification — a fraction of the cost of traditional instructor-led metrology training.
Ask in plain language. Get a real answer.
MET — your measurement field guide — explains the reasoning, shows the work, and points you back to the standard behind it.
uc is roughly one standard deviation of your result. On its own that only describes about a 68% interval. To report a range you can be confident in, you scale it by a coverage factor k to get the expanded uncertainty U = k · uc. For a result that’s approximately normal, k = 2 gives a coverage probability of about 95% — which is why you see it on most calibration certificates.
Grounded in: NIST GUM (JCGM 100) · ISO/IEC 17025:2017 §7.6
