This optical refractometer with three scales is designed for the measurement of coolants and antifreezes based on ethylene glycol and also for the measurement of battery fluid condition.
Scale / Characteristic Scale Range Resolution
Ethylene glycol -60 to 0 Centigrade 5 Centigrade
Ethylene glycol 0 to 100 % 5 %
Battery fluid 1.10 to 1.40 kg/l 0.01 kg/l
Measurement :
The liquid measurement is very easy.
Place a few drops of the liquid on the optical part of the refractometer,
cover the prism (the liquid will spread more easily over the prism),
look throught the eyepiece against the light (focus, if necessary)
and you will be able to read the result value on the scale.
Specification :
· reference temperature 20 Centigrade
· ATC - automatic temperature compensation (compensation range 0 ~ 30 Centigrade)
