Description
The Beer Refractometers YR05939 // YR05943 are indispensable tools for any brewing enthusiast, designed to measure the sugar density in a solution, providing instant gravity readings throughout the boiling process or mash runoff. These hand-held optical refractometers simplify the brewing process by eliminating the need for temperature adjustments or Brix to specific gravity conversions. They only require a small sample – just 2-3 drops – and are equipped with an Automatic Temperature Compensation (ATC) function, making them ideal for quick, frequent checks during sparging or running.
Market Pricing
The Beer Refractometers YR05939 // YR05943 are competitively priced within the market. Although each refractometer is available for purchase at $70.9, the general market range for similar quality refractometers is between $70 and $210. These devices offer excellent value for their advanced features and durable construction.
Frequently Asked Questions
How do I calibrate the refractometer? Calibration is straightforward; it involves adjusting the focus using distilled water. Detailed instructions are included with your purchase.
Do the refractometers require batteries? No, these devices use ambient light, so no power source is needed.
