Infrared refractometer

Non-destructive express measurement of sugar content

This new generation of refractometers allows rapid measurement of sugar content in fruits without cutting or squeezing.

Infrared measurement in a defined wavelength range is an established testing system in many other industrial applications. The measurement is made simply by placing the measuring optics on the surface of the fruit. It requires no more cumbersome wiping and cleansing after each measurement, as with conventional analog or digital refractometers.

Due to the preset calibration and different measuring ranges, a separate device is required for each type of fruit.
