We are an accredited calibration laboratory
What is calibration?
Calibration is an activity that under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication.

What is the difference between accredited and non-accredited calibration?
Accredited calibration is performed in accordance with calibration procedures approved by the ČIA (Czech Accreditation Institute). The calibration method is regularly validated and interlaboratory comparisons with ČMI (Czech Metrological Institute) is carried out. Calibration certificate bears the stamp of Accredited calibration laboratory and meets all requirements according to EN 17025 standard.
Non-accredited calibration is performed according to internal calibration procedures. Calibration certificate meets the requirements of EN 17025 standard.
Accredited and non-accredited calibration is performed using the instrumentation which is regularly calibrated by accredited calibration laboratories and ČMI.
What is metrological traceability?
Property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty.
Acc. to TNI 01 0115 (International vocabulary of metrology)
Traceability is a property of the measurement result or standard value, which determines the relation to national or international standards through unbroken chain of comparisons, stating the corresponding uncertainties. In essence, it is the inclusion the measuring instrument concerned into an uninterrupted sequence of transfer of a value starting from the standard of the highest metrological quality.
What is validation?
Verification, where the specified requirements are adequate for an intended use.

What is adjustment of a measuring system?
Set of operations carried out on a measuring system so that it provides prescribed indications corresponding to given values of a quantity to be measured.

What is measurement uncertainty?
Measurement uncertainty is a parameter associated with the measurement result that characterizes the dispersion of values that can be assigned to the measured quantity.
Interlaboratory comparison (ILC)
The subject of interlaboratory comparison (ILC) is a mutual comparison of measurement results with measurement results of the Reference Laboratory, which is the highest authority for a given area of measurements. The aim of the ILC is the demonstration of competence of accredited and non-accredited laboratories, including the validation of their measurement methods and established uncertainties. ILC is one of the methods ensuring the professional level of metrological laboratories and their services.
Can the laboratory, which calibrates your instruments and equipment, demonstrate You the competence to carry out these tasks and can it help You with nonconformities during the audit?
In the calibration certificate of accredited calibration, so called traceability is mentioned, which documents standards used for calibration. We are also able to assist You with nonconformities arising during audits.
