For reliable testing of coolant anti-freeze, battery acid and AD Blue in one unit

Simple test of display accuracy with distilled water

Automatic temperature compensation between 10°C–30°C

The exact measuring result is determined by the principle of optical refraction

Reliable display due to sharp light-dark separating line

Adjustable resolution to individual visual acuity

Differentiates between anti-freeze in propylene glycol and ethylene glycol

• Propylene glycol is mainly used as an anti-freeze agent outside Europe
• Ethylene glycol is mainly used as an anti-freeze agent within Europe

Precise result even with different composition

Includes:

• Optical tester
• 2 x extraction pipettes
• Calibrating screw driver
• Case
• Operating instructions
• Cleaning cloth

Instructions

1. Check whether prism and flap are clean

2. Using a pipette, place a drop of test liquid on the prism

3. Close the flap

4. A sharp light-dark dividing line will appear on the scale
