Extech RF41 Portable Battery Coolant/Glycol Refractometer
The Extech RF41 is used to accurately determine the specific gravity levels of ethylene/propylene glycol and can also be used to measure the overall freezing point of various types of coolant.
Available ranges on this refractometer are -50 to 0°C, Propylene Glycol freeze point, -50 to 0°C Ethylene Glycol freeze point and 1.15 to 1.30 Specific Gravity of Battery Acid. All measurements are calculated with automatic temperature compensation, ensuring that the effects of temperature do not have an effect on measurement accuracy.
Extech's RF range of refractometers are easy to use and can be used to determine repeatable measurements by adjusting the focus slightly. They also only require 2 to 3 drops of solution in order to operate.
