Physical-chemical quantities

AS Metrosert calibrates measuring instruments that measure liquid density, substance concentration, pH-level, electrical conductivity of liquids, relative air humidity, noise and gas content.

• density meters;
• aerometers and alcometers;
• pH meters;
• liquid electrical conductivity meters;

• dissolved oxygen meters;
• hygrometers;
• noise meters;
• alcometers.

• Motor vehicle’s exhaust gas content analyzers
• Evidential breath analyzers

We measure, if necessary, the density of liquids and the environment; air humidity; vibration of buildings and equipment.

• The measurements of density are traceable to the density measurement standard of Zentrum für Messen und Kalibrieren GmbH (Germany).
• The measurements of electrical conductivity are traceable via mass and volume measurement to the measurement standard of mass of the Estonian national measurement standard.
• The measurements of pH are traceable via the use of buffer solutions in the accredited laboratories.
• The measurements of gas content are traceable via the use of reference gas mixes calibrated in the accredited laboratories.
• The measurements of sound pressure are traceable to the measurement standards of the Swedish Metrology Institute (RISE).
• The measurements of relative air humidity are traceable to the measurement standards of the Testing Centre of the University of Tartu.
