Product Description
Robinair 75240 Coolant and Battery Refractometer: Automotive. The more concentrated the liquid, the more the light will bend. This model can be used for measuring the freezing point of either propylene or ethylene glycol based cooling systems. It can also be used for checking the strength of electrolyte solution batteries. This precision instrument features high-quality optics with ultra smooth focusing. Scale range: 32 Degree F to -60 Degree F. The 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 refractometer contains a reticle, or scale, that is enlarged through the eyepiece to measure this bent light.
