Reliable readings for professionals: measures ethylene glycol (G11/G12) and propylene glycol (G13) antifreeze with a freezing point of 0 to -50°C, windscreen washer water (ethanol water or propylene glycol water) from 0 to -40°C, AdBlue with a urea concentration of 30-35%. as well as battery With a density of 1.10-1.40 kg/L - ideal for comprehensive winter maintenance with just one device.
PRECISE MEASUREMENT & DURABLE DESIGN Equipped with a high-resolution prism and an optical quartz lens, the antifreeze tester delivers accurate readings on a clear readable scale - reduces reading errors and avoids economic loss. The coolant tester housing made of high-quality aluminium alloy is lightweight, portable, rust-proof and shockproof - ideal for workshop, garage and long-term use.
ATC Function - Automatic Temperature Compensation: Thanks to the antifreeze blade with automatic temperature compensation (ATC) in the range of 10 °C to 30 °C, the antifreeze tester automatically adjusts the readings for antifreeze to temperature fluctuations. This means that the results remain stable and reliable both in the workshop and in outdoor use.
4 IN 1 ANTI-FROST MEASUREMENT - READY FOR SAFE WINTER: This refractometer not only accurately measures the freezing point of ethylene glycol or propylene glycol based antifreeze in cars, solar systems, heat pumps and heating systems, but also the acid density of battery acid, freezing point of windshield washer water, as well as the concentration of AdBlue, making it an essential tool to get vehicles and and household appliances safe through winter.
