PROPYLENE / ETHYLENE GLYCOL 75240 ROBINAIR REFRACTOMETER

PROPYLENE/ETHYLENE GLYCOL 75240   ROBINAIR REFRACTOMETER

The Robinair 75240 Hand Refractometer is a portable, precision optical instrument used for measuring the freeze point of engine coolant and the operation state of battery charging liquid.

It is used on transportation vehicles, such as cars, tractors, tanks, ships, etc., which use propylene or ethylene glycol for coolant and sulphuric acid for charging liquid. When a liquid (such as coolant or charging liquid) is placed on the prism, the light passing through it is bent. The more concentrated the liquid, the more the light will bend. The refractometer contains a reticle, or scale, that is enlarged through the eyepiece to measure this bent light. The values of the scale have been established to evaluate the coolant or charging liquid.
