Honey Refractometer - 58 to 90% with ATC, NIST-Traceable Certificate

Professional Grade Honey Refractometer (3-in-1 Scale) with NIST Certification

Master Your Honey Harvest with Lab-Grade Precision

Eliminate the guesswork from your apiary management. The Sper Scientific Honey Refractometer is the definitive tool for beekeepers and honey producers who demand consistency. By providing instant, accurate readings of moisture, sugar, and density, this device ensures your honey is harvested at the peak moment—preventing spoilage and guaranteeing a premium product.

Whether you are a hobbyist managing a few hives or a commercial producer ensuring compliance with food safety standards, this optical instrument is your first line of defense against fermentation.

Why This Tool is Essential

Honey is hygroscopic, meaning it absorbs moisture from the air. If harvested with a water content above 17-18%, natural yeasts can cause the honey to ferment and sour. This refractometer allows you to:

• Prevent Fermentation: Instantly verify if water content is within the safe 10-33% range.
• Grade Your Product: Use the Brix scale (58-90%) to determine sugar concentration and quality tiers.
• Check Density: The Baume scale (38-43°) helps assess the specific gravity and viscosity of your harvest.

Key Features & Benefits

• Advanced Automatic Temperature Compensation (ATC): Honey viscosity changes with heat. Our built-in ATC allows you to take readings in the field or the honey house (between 10°C to 30°C) without manual calculation corrections. The device automatically adjusts the reading to account for ambient temperature.
• NIST Certified Accuracy: Unlike standard market options, this unit comes with a Certificate of Calibration. It is tested in an in-house laboratory to meet or exceed published specifications, complete with a serial number and testing report—ideal for QA documentation.
• Superior Optical Clarity: Features a cushioned, soft rubber eyepiece with an adjustable manual focus. This ensures that the dividing line between blue and white (your measurement) is razor-sharp and easy to read, even in variable lighting.
• Field-Ready Durability: Constructed with non-corrosive, heavy-duty materials and a rubberized non-slip grip, this tool is designed to withstand the rigors of beekeeping environments. It requires no batteries, making it reliable indefinitely.
