Overview of Metrology

The Science of Accurate Measurement

Metrology is the science of measurement and its application. It ensures that measuring devices used in industries, medical facilities, testing laboratories, trade, and daily services are accurate and reliable.

Everyday Relevance

Questions Metrology Helps Answer

Is my blood pressure reading correct?
Is the weighing scale accurate?
Is the gas pump dispensing the right quantity?
Is my body temperature reading reliable?

Reliable Trade

Supports fair transactions through trusted measurement references.

Public Safety

Helps reduce risks caused by inaccurate clinical and safety instruments.

Industrial Accuracy

Improves confidence in production, laboratories, and quality systems.

Global Confidence

Promotes common understanding through SI measurement units.

Services Offered

Measurement Services Built Around Accuracy and Trust

LiSA’s Metrology Department supports organizations, laboratories, industries, and consumers through reliable measurement services.

Traceability to SI Units

Providing measurement traceability so results can be related to national or international standards.

Calibration of Instruments

Evaluating the accuracy of measuring instruments using standards of higher accuracy.

Measurement Consultancy

Providing technical support and professional guidance in measurement technology.

Why Calibrate?

Calibration Helps Detect Hidden Errors Before They Cause Loss, Risk, or Wrong Decisions

!

The Deceit

An instrument may appear normal, but the value displayed can be far from the true value. Calibration exposes these errors.

Safety

Accurate thermometers, blood pressure devices, x-ray machines, and scales support proper diagnosis and safe decisions.

$

Trade

Inaccurate weighing scales, fuel dispensers, and production instruments can cause financial loss for businesses and consumers.

Scientific & Industrial Metrology

Core Technical Services

The unit supports reliable measurements through calibration, verification, and traceability.

Calibration

A process of evaluating the accuracy of a measuring instrument by means of a known standard of higher accuracy.

Verification

A process carried out to evaluate instruments used for trade or trade-related activities under normal conditions of use.

Traceability

Measurement results are related to a stated reference through an unbroken chain of calibration.
