Hand Refractometer RF.6650 — handheld refractometer for glycol and screenwash testing, 1.10–1.40 sg, 0.01 accuracy (Euromex)

The Hand Refractometer RF.6650 is a portable instrument designed for quick determination of specific gravity in battery fluids, ethylene glycol and propylene glycol coolants and screenwash solutions, enabling routine checks in workshops and maintenance bays.

• 1.10–1.40 specific gravity measuring range
• High precision with 0.01 resolution
• Suitable for ethylene/propylene glycol and screenwash

Accurate readings where they matter most

This handheld instrument provides reliable measurement across a 1.10–1.40 range with a resolution of 0.01, which is sufficient for routine verification of glycol concentrations and related fluids. The value shown as specific gravity is a direct indicator of solution concentration; technicians can rely on the precision to detect deviations from expected composition that might affect freezing point or corrosion protection. Clear numerical output minimises interpretation errors and supports documented maintenance records.

Practical benefits for workshop and fleet maintenance

Compact and simple to carry, the refractometer is suited to bench or field use in garages and fleet workshops. Frequent checks using a device with 0.01 accuracy reduce unscheduled downtime by revealing diluted or contaminated fluids early. The instrument’s handheld format allows fast spot checks on coolant systems and screenwash reservoirs, helping to plan replenishment and maintenance work efficiently while maintaining process reliability.

Interpreting measurements for safer operation

A reading within the 1.10–1.40 window corresponds to concentrations typically found in automotive and industrial glycol formulations. Interpreting specific gravity values helps infer freeze protection level and effective inhibitor concentration; consistent monitoring with this refractometer supports evidence-based decisions about topping up or replacing fluids. Where fluid condition is critical for performance or safety, regular checks with a precise instrument provide a documented, rational basis for action.

Robust concept with low handling complexity

Designed for routine use rather than laboratory analysis, the instrument is uncomplicated to operate and well suited to users with limited metrology background. The compact design and straightforward measurement principle mean staff training time is reduced while enabling quick readings during scheduled inspections. Where traceability matters, the device supports standard operating procedures by producing consistent, reproducible values that fit into quality workflows.
