Handheld antifreeze tester designed to check coolant freezing points, battery acid density, AdBlue concentration and washer fluid quickly and accurately. Gives DIY mechanics and fleet technicians confidence when assessing winter readiness. Is the HXTDBY Antifreeze Refractometer a sensible addition to routine maintenance kits?
⚡ At a Glance
- • Measurement Range: Ethylene glycol 0 to -50°C; propylene glycol 0 to -50°C; battery acid 1.10–1.40 kg/L; washer fluids 0°C to -40°C depending on solvent; AdBlue urea 30%–35%.
- • Best for: DIY mechanics, fleet maintenance and homeowners needing quick fluid diagnostics
- • Not ideal for: Laboratory-grade analysis or users requiring digital logging and traceable calibration records
Handheld optical refractometer capable of four fluid checks. Automatic temperature compensation and robust materials improve reliability in workshop conditions.
Accurate freeze-point readings, with calibrated refractometer optics
Prism-based optical measurement requires 2–3 drops of sample placed on the prism and reading through an eyepiece; stepless manual focus lets users sharpen the scale for precise observation. Calibrated scales map refractive index to freeze-point values for ethylene and propylene glycols.
Quickly establish coolant protection down to -50°C, helping prevent freeze-related failures during cold weather. Clear optical scales make pass/fail checks fast on the workshop bench.
Rapid battery and washer-fluid checks, with specific gravity and solvent scales
Dedicated density scale measures battery acid from 1.10 to 1.40 kg/L, while washer-fluid scales cover ethanol and isopropyl mixes to show freezing protection to -40°C. Readings require only a tiny sample and a simple visual observation.
Assess battery condition and washer fluid winter readiness in seconds, avoiding surprise failures. Ideal for routine checks before long journeys or seasonal maintenance.
Built for regular use, with aluminium and ABS rubber construction
Non-staining aluminium and ABS rubber resist rust and abrasion, while the lightweight build keeps handheld fatigue to a minimum. The surface materials are easy to wipe clean after fluid testing.
Durable enough for workshop or roadside checks and simple to maintain between uses. Portability encourages more frequent checks, improving overall vehicle reliability.

❓ Frequently Asked Questions
Q: What fluids can be tested with the refractometer?
A: Coolant (ethylene and propylene glycol), battery acid, windshield washer fluids (ethanol and isopropyl mixes) and AdBlue urea concentration are supported according to the supplied scales.
Q: How is a reading taken?
A: Place 2–3 drops of the sample onto the prism, focus the stepless eyepiece and read the appropriate scale through the eyepiece for an immediate result.
Q: Does the tool correct for temperature differences?
A: Automatic temperature compensation works between 10°C and 30°C to help maintain accurate readings without manual correction.
🏆 Our Verdict
The HXTDBY Antifreeze Refractometer suits DIY mechanics, fleet technicians and homeowners who need fast, repeatable fluid checks. Wide measurement ranges and the ability to test AdBlue as well as coolant and battery fluids make it especially useful for mixed-vehicle workshops. Although actual cost depends on retailer, rugged build and multi-function use offer good long-term value for routine maintenance.
