The refractometer is a measuring instrument for the determination of the antifreeze content in aqueous solutions, such as in windscreen washer tanks or in cooling systems of cars or trucks. With this refractometer you can also specify the density of battery acid. By using this refractometer you measure quickly as well as exactly the content of antifreeze in systems and machinery. This handy refractometer can be used both in the automobile and in the industrial sector. The refractometer is ideal for testing the concentration of ethylene glycol and propylene glycol-based coolant. The refractometer has sharp limitation lines and a diopter that ensures for a precise and exact measurement result. The refractometer is supplied with a cleaning cloth, a pipette for liquid application and a mini screwdriver for recalibration. Function By the use of the included pipette, the liquid to be tested is given onto the prism. Fold down the cover of the refractometer and read on the scale the Coolant concentration that was achieved for the selected liquid. Make sure that there are no air bubbles or dry spots on the prism. If necessary, refill with liquid.
