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.

(Antifreeze / Battery Fluid / Windscreen / AdBlue)
Instruction manual
Close the lid (1) to disperse the fluid evenly with equal opacity / no bubbles.
4.1 Read the test procedure.
4.2For "Propylene Glycol" read the left side of Scale A. For "Ethylene" read the right side of
Scale A.
5.1 Read the test procedure
5.2 Refer to Scale B. Note: variations in formulation of windscreen washer fluids may result in
an average value for a variety of alcohol based anti-freeze mixtures, this test is therefore a
guideline only.
6.1 Read the test procedure.
6.2 Refer to Scale C which indicates the density of the battery fluid in kg per litre and the ranges for
Recharge, Fair and Good.
7.1 Read the test procedure.
7.2 Refer to Scale D which Indicates the percentage of urea to distilled water in AdBlue; 32.5
indicates the most desirable percentage of urea in the solution.
8.1 Keep unit clean. Protect eye lens, display lid and prism to prevent scratching.
8.2
8.3 To test instrument accuracy, place distilled water on the prism and check that the LIGHT-
DARK dividing line is level with the "WATERLINE". If the reading is incorrect remove the
black rubber cover from the calibration point (6). Insert the small supplied screwdriver into
the hole in the calibration point. Turn the screwdriver whilst looking through the eyepiece until
the waterline mark is on the light-dark dividing line.
8.4 After use and cleaning store in supplied foam lined and plastic case.

7. ADBLUE TEST
8. MAINTENANCE / CALIBRATION
For best results an ambient temperature of 20 degrees C for both the refractometer and the
fluid being tested is recommended.
