The Refractometer OTR304 indicates the freezing temperature of coolant and windscreen water, the density of battery acid and the quality of AdBlue®*.
- 4 functions in 1 tester
- Switchable LED illumination for use in bad light conditions.
- Suitable for use on coolant additives such as G 11, G 12,G13
- Automatic temperature compensation
- Result is easy to read on the dark/light dividing line.
For testing coolant or windshield washer fluid, a light/dark dividing line is shown on the scale, up to which the temperature in °C(optional in °F) of the coolant or windshield washer fluid is protected against freezing. For testing battery acid, the acid concentration is displayed in kg/l and, in turn, broken down into grades such as recharche/fair/good.
Measuring Range:
Ethylene /Propylene : -50-0°C
Battery Fluids : 1.100-1.400kg/l
Urea : 30%-35% (32.5% is the standard Level )
Cleaner : -40~0°C
