Achieve instant, highly accurate concentration measurements for your critical laboratory, food & beverage, and industrial applications with the Heathrow Scientific Handheld Refractometers (43000 Series). Built to survive rigorous daily use in both the field and the lab, these optical instruments feature a rugged all-metal housing designed to facilitate rapid temperature equilibrium between the sample and the premium optical glass prism. This ensures your readings are not only lightning-fast but reliably consistent across varying ambient environments.
Available in both Brix (Sugar/Aqueous) and NaCl (Salinity) scales, these refractometers are designed with the end-user in mind. The best-in-class, extra-large internal scale delivers incredibly sharp contrast and clear figures, eliminating the guesswork and eye strain common with cheaper alternatives. Furthermore, an integrated slip-resistant rubber grip guards against hand heat transfer, which can otherwise skew delicate measurements. Several models feature Automatic Temperature Compensation (ATC), while non-ATC models utilize a patented "Zero-Ring" for rapid, tool-free calibration.
Features & Benefits
- Premium Optical Glass: High-quality prism construction ensures sharp contrast and rapid thermal equilibration for accurate readings.
- Thermal Isolation Grip: A specialized rubber housing grip prevents body heat from transferring to the internal optics and altering the reading.
- Tool-Free Calibration: Non-ATC models feature a patented Zero-Ring that allows for immediate calibration without the need for micro-screwdrivers.
- Rugged Metal Housing: Industrial-grade metal construction stands up to drops, impacts, and heavy field use better than plastic competitors.
- Non-Roll Stand: A strategically designed body stand prevents the instrument from rolling off the benchtop and shattering.
