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.
