The purpose of such laboratories is to perform all types of measurements of physical quantities and calibrations of measuring instruments. Measurement laboratories develop, validate and improve measurement procedures. They are usually accredited by PCA, which by means of cyclical audits verifies whether the activity of a measuring laboratory is conducted in accordance with the declarations included in the documents of quality system, and calibrations are performed in strictly defined conditions according to the established measurement procedures.
An official document usually issued by the Central Measurement Authority, county offices, accredited or non-accredited measurement (calibration) laboratories, containing the results of calibration of a measuring instrument and certifying that the calibrated instrument meets certain metrological requirements.
This is the lowest uncertainty of measurement that a calibration laboratory can achieve with routine calibration and is usually the expanded uncertainty with a probability of expansion of approximately 95 % and a coverage factor of k = 2.
Those meeting the requirements of PPN-EN ISO/IEC 17025: 2005 standard are obliged to ensure measurement consistency. Calibration laboratory within its accreditation scope cannot issue calibration certificate with extended uncertainty less than the one given and confirmed as CMC. However, it does not mean that each measuring instrument calibrated in a given Laboratory will be provided with a measurement uncertainty equal to CMC on the certificate (it is within the scope of Laboratory accreditation on the PCA website and on the website of the Accredited Calibration Laboratory no. AP 156).
The uncertainty of measurement depends on many different components of the uncertainty budget, such as the resolution of instrument or scattering of the instrument readings. Usually the uncertainty given on the certificate is slightly higher than CMC (with very used up calibration instruments with large errors and low repeatability of indications, the uncertainty may be significantly higher than CMC).
The concept is derived from the method of determining the result of a measurement called uncertainty calculus (theory) recommended since 1993 by international standardizationorganizations and denoting a parameter associated with the values (series) of a physical quantity under constant conditions that can reasonably be attributed to the measurand value and characterizing its dispersion within a range, which the value of measurand can be satisfactorily placed. The uncertainty of measurement results from the fact that it is always inaccurate, which is not only due to imperfections of the apparatus and senses of the observer, but is an inherent feature of such an operation.
The purpose of calibration is to determine the metrological condition of a calibrated instrument that determines its suitability to perform measurements, including providing a measurement unit, or to certify that a calibrated instrument meets the manufacturer’s specific metrological requirements and technical specifications, while the calibration result is certified in a calibration certificate. During calibration, measurement consistency is maintained, i.e. a continuous sequence of references to national or international standard.
A measuring instrument, reference material, physical value or measuring system designed to define, execute, preserve or reproduce a measurement unit, one or more values of a certain quantity and used as a reference.
The international uniform temperature scale is based on temperature values at points characteristic of several chemical compounds, e.g. the triple point of water, oxygen, or the melting point of copper at 101325 Pa. In its present version it has been in force since 1990. (ITS 90). Previously, the ITS 68 scale was in force.
Temperature measurement using the physical properties of measuring sensor, measurement with the deformation phenomenon of bimetal electric voltage production at the contact of two metals at different temperatures (thermocouple) change in resistance of the element (thermistor, change of semiconductor connector parameters (diode thermometer) change in the volume of liquid, gas or solid length (thermometer, liquid thermometer), parameters of thermal radiation of the body (pyrometer).
Prices of services are given on the basis of our price list or prices of subcontractors, if necessary.
ANMAR Poland is very competitive on the market and we monitor prices of similar companies on an ongoing basis.
In order to provide our customers with service at the highest level, our calibrators and meters are serviced and calibrated by laboratories accredited mainly in: The United States, UK, Netherlands or Germany.
Other laboratory instruments are calibrated in Polish companies. PCA auditors regularly verify our procedures and quality system.
ANMAR Poland will present an offer for calibration of measuring instruments in response to an inquiry received from you. Depending on the type of instrument and calibration conditions, e.g. number and measurement points, time period of calibration.
If these conditions are not specified in the inquiry, the laboratory will perform standard calibration according to the manufacturer’s procedure or any other available procedure.
The type of procedure will be indicated on the Calibration Certificate that you will receive from our laboratory.
Calibration conditions accredited in accordance with ISO 17025 are strictly defined by the accrediting body, in Poland it will be the PCA.
Each offer will include the insurance and shipping costs of the instrument.
This cost must be included in the service order based on this offer, it may be omitted if you indicate the courier company and your customer number in their database. Please carefully pack your shipping equipment, so that it can safely reach our laboratory.
In this regard, we would like to inform you that in our company the process of unpacking and packaging is monitored and recorded. This applies to each shipment. This helps in disputes with customers as well as with courier companies.
