1.1. General Safety
Familiarise yourself with the applications and limitations of this refractometer.
Keep the meter clean and in good condition.
DO NOT
use the meter for any purpose other than that for which it is designed.
WARNING! When testing fluids, especially battery fluid, ensure that none comes into
contact with your eyes or skin since serious injury could result. Wear protective gloves
and clothes. Ensure that all general workshop safety rules are applied.
This meter measures the strength of battery fluid, windscreen wash, antifreeze and AdBlue by
measuring the refractive index of light passing through the mixture. Suitable for synthetic
antifreeze mixtures including long life OAT (Organic Acid Technology) and aqueous / urea content
of AdBlue. Temperature corrected prism ensures accuracy. Eyepiece with adjustable focus.
Simple calibration check using distilled water. Supplied with pipette and carry-case.
3.1
Check that the prism (2) and lid (1) are clean.
3.2
Open lid, hold tester so that prism surface is level and with pipette supplied (4), place a drop
of the fluid onto the prism (2).
3.3
3.4
Turn eyepiece (3) so that the display is correctly focused.
3.5
Read off the value, on the appropriate scale, indicated by the pronounced LIGHT-DARK
dividing line.
On completion of each test carefully clean the prism with a lint-free dry cloth (5). The tester
incorporates a display, subdivided into five scales (fig. 2) from which to check the following
fluids.
