Refractometer NEO tools TOP-11-270 — handheld optical instrument for measuring refractive index and concentration

Handheld refractometer NEO tools TOP-11-270 is a compact optical instrument for measuring the refractive index and concentration of clear liquids. Designed for rapid field or laboratory checks, the device provides direct visual readings through its optical prism and scale. The instrument is suited for basic quality control tasks where quick assessment of liquid concentration or refractive index is needed, including automotive fluids, coolants, battery electrolytes and simple food and beverage testing.

Advantages

The refractometer offers a portable, low-maintenance solution for on-site measurements without the need for power supply. Its optical system delivers immediate readings with minimal sample volume and straightforward calibration. Rugged construction supports use in workshop and field conditions while the clear scale allows fast interpretation of results. The device is lightweight and ergonomically shaped for comfortable handheld use.

Suitable for

• Quick verification of coolant and antifreeze concentration
• Checking battery electrolyte strength
• Basic quality checks of clear food and beverage samples (e.g., syrups, juices)
• On-site testing of automotive fluids and maintenance liquids
• Field or laboratory spot checks where refractive index or concentration is required

Key specifications

• Optical handheld refractometer design for manual readings
• Measuring range suitable for common liquid concentration and refractive index checks
• Direct visual scale for immediate result interpretation
• Small sample volume required for measurement
• Durable housing for workshop and field environments
• Ergonomic form factor for one-handed operation

How to use

Place a few drops of the liquid sample onto the clean measuring prism, close the cover plate if applicable, and point the instrument toward a light source. Look through the eyepiece and read the value where the light-dark boundary crosses the scale. If necessary, perform a calibration with distilled water or a reference solution following the manufacturer's standard procedure before taking measurements. Clean the prism and cover plate after each measurement to avoid cross-contamination.

Usage recommendations

For reliable results, ensure samples are free of suspended solids and bubbles, measure at a stable ambient temperature, and recalibrate periodically. Use within the device's specified measuring range and avoid exposing the instrument to strong shocks or prolonged moisture to maintain accuracy and longevity.
