Calibration fluid
A calibration liquid is a reference material in its liquid state. The calibration liquid is used to calibrate analytical measuring instruments in physico-chemical or similar laboratories .
Measuring device and calibration liquid
Depending on the measuring device to be calibrated , a certain calibration liquid is used:
- Density meters are calibrated with water
- Volumetric measuring devices (e.g. volumetric flasks ) are calibrated with water
- pH meters are calibrated with buffer solutions
- The polarimeter is calibrated with sucrose solution
- Refractometers are also calibrated with certified reference materials
