Battery Coolant Refractometer
The Baker Instruments B3090 measures the freezing point of Ethylene Glycol and Propylene Glycol coolants. It also checks battery fluid condition for automotive and industrial maintenance. Technicians use it to verify coolant protection levels quickly.
Automatic Temperature Compensation
Built-in ATC adjusts readings across ambient temperature changes without manual correction. This single feature determines whether the instrument delivers reliable data in a cold bay or a hot workshop.
Simple Optical Operation
Place a few drops on the prism, close the cover and read the scale through the eyepiece. No power source or calibration fluids are required. The only common error is applying too much sample, which blurs the boundary line.

Questions about this item
How does the B3090 refractometer show the freezing point of coolant in a real workshop?
It reads the refractive index of the fluid and applies Automatic Temperature Compensation so the displayed freezing point is correct whether the sample is hot or cold.
What measurement standard does the Automatic Temperature Compensation follow and what range does it cover?
The ATC function adjusts the reading to a reference temperature automatically; the instrument is calibrated for both Ethylene Glycol and Propylene Glycol scales.
What does the B3090 need to sit on or connect to for bench use?
It is a hand-held optical unit that requires only a few drops of coolant on the prism and a light source; no power supply or mounting hardware is needed.
