Introduction:
These model coolant refractometer can be used for measuring the freezing point. They can you whether the antifreeze contains the right amount of either ethylene glycol or propylene glycol antifreeze solution, coolant refractometer can also be used for checking the strength of electrolyte solution batteries, and testing the cleaner water too.

FAQ:
1.What is a refractometer?
There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases. In veterinary medicine, a refractometer is used to measure the total plasma protein in a blood sample and urine specific gravity in a urine sample.
2.What is a refractometer and how does it work?
When light enters a liquid it changes direction; this is called refraction.Refractometers measure the degree to which the light changes direction, called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established.
3.What is the function of the refractometer?
Refractometers are mostly used to determine the index of refraction of liquid samples, and to measure fluid concentrations, such as blood protein concentration, sugar content, and salinity.
4.How does a hand refractometer work?
A traditional handheld refractometer is an analog instrument for measuring a liquid's refractive index. It works on the critical angle principle by which lenses and prisms project a shadow line onto a small glass reticle inside the instrument, which is then viewed by the user through a magnifying eyepiece.
5.How do you measure the specific gravity of a liquid?
Obtain the density for the liquid in question. The density of a substance is equal to its mass divided by its volume. You can measure the mass on a scale and record the volume of the liquid used. Use the equation "m / v = D" where m is mass in grams or kilograms, v is volume in milliliters or liters, and D is density.
