For motorists keen to avoid unexpected winter breakdowns, QWORK Antifreeze Refractometer makes routine checks quick and readable. Can workshop-level reassurance be achieved without specialist training?
⚡ At a Glance
- • Measurement Range: Antifreeze -50 to 0°C, windshield water -40 to 0°C, battery liquid SG 1.10–1.40, urea 30–35%
- • Best for: Car owners, workshop technicians and heat pump installers needing quick fluid checks
- • Not ideal for: Situations requiring digital logging or automated multi-sample testing
Aluminium alloy construction gives high corrosion and wear resistance. Four-measurement capability covers ethylene and propylene glycols, urea and battery acid.
Trustworthy freeze-point readings - with clear prism calibration
Place one or two drops of sample on the prism and close the cover, then calibrate using distilled water and the adjustment button until the blue/white boundary aligns with the 0°C baseline. The optical boundary indicates refractive index changes that correspond to freeze point readings.
Accurate freeze-point numbers let users confirm coolant protection for winter, reducing the risk of frozen engines. Simple calibration keeps routine checks reliable without specialist equipment.
Four fluids tested with one instrument - thanks to multi-parameter capability
Designed to measure ethylene glycol, propylene glycol, automotive urea and battery acid specific gravity, with dedicated measurement ranges for each fluid type. The optical scale and matched ranges allow direct interpretation for different formulations.
One tool covers coolant, washer fluid, urea and battery checks, saving time and kit space. Suitable for owners who service vehicles and for technicians carrying out quick diagnostics.
Built to withstand workshop use - with aluminium alloy construction
Aluminium alloy body improves resistance to corrosion and wear common in garage environments, helping maintain optical alignment and mechanical controls during regular use. The mechanical calibration button allows repeat adjustments without electronic reliance.
Durable construction means fewer failures from exposure to workshop conditions and long-term dependable readings. Positive user feedback highlights consistent performance and value for routine maintenance.
