Handheld refractometer with light function, for measuring frost protection *KB*

• With light function
• For fast and accurate antifreeze measurement of solar, heat pump and cooling system fluids
• For measuring the ice flake point at which the antifreeze begins to freeze
• With additional refractive index scale (nD20) for determining other liquids
• 2 refractometers in one for measuring the freezing point of common antifreeze and the refractive index of various liquids

Antifreeze scales based on:
• Propylene glycol, measuring range 0°...-45°C (solar, heating and cooling systems)
• Ethylene glycol, measuring range 0°...-45°C (heating)
• Ethanol, measuring range 0°...-42°C
