It is used for measuring and controlling the concentration of an emulsion (COOLANT), since during the operation of coolant, the concentration is measured by evaporation, entrainment, and so on.
A refractometer is a device designed to measure emulsion concentrations, which can be divided into two types: electronic digital; optical manual.
The cost of an optical hand-held refractometer is almost three times lower than a digital one.
The main advantages of the optical hand-held refractometer are its low cost, reliability, and ease of use.
The main advantages of a digital hand-held refractometer are its ease of use, measurement accuracy, and reasonable cost.
A digital refractometer is a device designed to measure refractive indices.
This is a device that allows you to monitor the concentration of coolant.
This device is the simplest for measuring the concentration of a coolant or other emulsion, without using complex equipment or reagents.
The concentration measurement takes only a few seconds.
The principle of operation of the refractometer is that a ray of light penetrates into a liquid, thereby refracting on its surface.
The refraction size is based on the concentration of solutes.
The refractive index is determined by the ratio of the angles of entry of the light beam and the refraction of the liquid.
Refractometers are in high demand both for measuring the concentration of coolant and for oils, lubricants and other technical liquids.
Most often, the measurement range is quite small, from a maximum of 0-33%.
But it happens that quite small concentrations of emulsions are used, which is why we recommend choosing a device, taking into account the range of its measurements.
