Handheld Refractometer for aircraft deicing fluid

DESCRIPTION

Refractive index and Refractometer

Aircraft deicing fluids are usual delivered in concentrated form, mean 100% or 100/0 and can be diluted with water if necessary. E.g. depending on freezing point or holdover time. Regular checks are required for a safe winter operation.

The glycol water content in liquid mixtures can be determined by using a refractometer. The glycol-proportion is directly related to the mixture ratio and freezing point of the fluid. The measured refractive index can be used related to the freeze point/ mixture curve and – tables from manufacturer of the deicing fluids. For further information please refer for the respective specifications for aircraft deicing.

TECHNICAL DATA

Calibration

The refractometer is calibrated to read correctly at 20°C. The refractive index of the measured sample will vary with temperature. Therefore it is important, that measurement with the refractometer takes place at 20°C.

The accuracy of the instrument may be checked using a simple test.

Use distilled water. Apply a sample of distilled water and check that the R.I. reads 1,333 (+/- 0,002)

This sample can be performed in regular intervals as a part of security quality-control program. The refractometer has not to be send in. The check can take place in your company.
