Practice video

Calibrate handheld refractometers correctly

A handheld refractometer is an indispensable measurement device when precise values are required for water, sugar or salt content. Whether in food control, beverage production, beekeeping or in the laboratory – correct calibration is the basis for precise analyses and high measurement quality.

Regular calibration: Temperature changes, wear and tear or environmental influences can affect the accuracy of a handheld refractometer. Regular calibration detects such deviations at an early stage and ensures that the device continues to work precisely. A well-calibrated refractometer provides consistent results and prevents measurement errors that can be caused by external factors.

Application example

HRKFZ-T for checking cooling lubricants

Handheld refractometers are also used to quickly determine concentrations in cooling lubricant emulsions. Here are a few examples:

Measurement of ethylene and propylene glycol
Conversion via a product-specific correction factor
Immediate control directly at the machine
Advantages: Protection against corrosion and bacteria formation; optimum lubricating and cooling effect; no laboratory analysis required
