Refractometer 200mm

• Used to measure the freezing point of ethylene glycol or propylene glycol in a cooling system, the freezing point of windscreen cleaning fluid, the density of the electrolyte in the battery, or the concentration of urea in the AdBlue tank
• Specification range:
• - 50°C to 0°C (propylene glycol) and -50°C to 0°C (ethylene glycol)
• 1.10 to 1.40 kg/l for the specific gravity of battery electrolyte
• -40°C to -10°C for the frost resistance of windscreen cleaning fluid
• 5% to 40% for the urea concentration (AdBlue) │ Features a focusing eyepiece that provides a sharp, easy-to-read scale
• Ambient room light provides adequate illumination, no special direction or angle required to view reading
• Includes a steel and glass head and prism, rubber finger grip, and focusing eyepiece with eyecup
