Digital Hand Refractometer RD.6730 — handheld refractometer, 1.0–1.50 sg range, 0.01 resolution (Euromex)

The Digital Hand Refractometer RD.6730 is a compact instrument for rapid specific‑gravity checks of battery fluids, ethylene and propylene glycols and windscreen washer liquids.

• Portable handheld refractometer design
• Measurement range 1.00–1.50 sg
• Resolution 0.01 for accurate readings
• Suitable for glycols and washer fluids

Faster, traceable checks to support maintenance cycles

The RD.6730 delivers specific gravity readings within a 1.0–1.50 sg range with a 0.01 resolution, which provides a clear, verifiable basis for service decisions. Specific gravity is a standard measure of fluid concentration and, for workshop purposes, correlates directly with freeze protection and battery state‑of‑charge effects. By using a digital handheld refractometer, routine inspections become repeatable and documentable, helping to avoid premature component failure and unnecessary fluid changes.

Portable testing that fits inspection workflows

Thanks to its handheld format, this digital refractometer is suited to quick, on‑site checks across vehicles and plant equipment. The unit’s compact form supports mobility in confined areas and fast sampling at the point of service, so measurement can be integrated into established maintenance routines without delay. With clear numerical output and fine resolution, the instrument enables immediate assessment that can be recorded for trend analysis or linked to maintenance logs.

Practical interpretation for workshop decision‑making

Readings obtained with the device translate directly into actionable information: a given specific‑gravity value indicates the concentration of ethylene glycol (G13) or propylene glycol (G11/12) and therefore the expected freeze protection within the ranges stated on the device label (for example, up to −50°C for certain glycol concentrations and down to −40°C for typical windscreen washer formulations). Interpreting these values supports targeted topping up or fluid replacement and reduces unnecessary waste. For users unfamiliar with refractometry, the method measures the refractive index of a liquid and converts it into specific gravity — a measurable, industry‑recognised parameter for fluid condition assessment.

FAQ

Which liquids can be measured with this refractometer?
The RD.6730 measures specific gravity for battery fluids and glycol‑based coolants; the label explicitly lists ethylene glycol (G13), propylene glycol (G11/12) and windscreen washer fluids.

How precise are the measurements?
The instrument provides readings with a 0.01 resolution, allowing fine discrimination of fluid concentration for maintenance decisions.

Is the unit suitable for field inspections and quick checks?
Yes, the handheld design supports mobile testing and rapid on‑site assessments without the need for bench equipment.

How should the results be interpreted for freeze protection?
Specific gravity values relate to glycol concentration and thus to freeze protection; the product label indicates the typical temperature ranges associated with the listed formulations.

Is routine calibration necessary?
Calibration is recommended according to manufacturer guidance to ensure continued accuracy; the RD.6730 should be checked periodically against a known standard.
