Application

The 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.

The reticle without

any liquid on the

prism.

The reticle with liquid on the

prism. The reading is taken at

the point the shadow line

crosses the scale.
