Product Overview

Up for sale is the highly specialized BOSS Coffee, Tea & Espresso (CT&E) Analog Refractometer and TDS Meter. As a uniquely engineered handheld analog optical device, this instrument gives you an incredibly accurate, reliable, and affordable way to measure the Total Dissolved Solids (TDS) and Brix percentages of your extractions. It provides the exact clarity you need to track your finished liquid profile, dial in complex brewing recipes, and maintain absolute batch-to-batch flavor consistency without dropping hundreds of dollars on fragile digital equipment.

Whether you are pulling espresso shots, monitoring a cold brew configuration, adjusting coffee concentrates, or dialing in specialty teas, this portable meter integrates seamlessly into your workflow. It works perfectly alongside major brewing apps on the market, giving you a professional data edge for a fraction of the cost.

What is a TDS Meter & How Does it Help?

TDS stands for Total Dissolved Solids. A refractometer measures how light bends as it passes through your beverage sample, giving you a precise visual reading of how much flavor material you have successfully extracted from your grounds. For example, a quality, ready-to-drink cold brew typically registers right around a 1.6 TDS baseline, while higher-strength concentrates push significantly further up the scale. Tracking this data allows you to balance strength, prevent over-extraction, and save money on wasted beans.

• Application Scope: Specialized for Coffee, Tea, Espresso, and High-Density Concentrates
• Measurement Targets: Dual-scale monitoring for both % Brix and % TDS
• Optical Design: Handheld, portable analog prism layout with adjustable manual focus eyepiece
• Features: Built-in Automatic Temperature Compensation (ATC) to ensure steady, reliable readings regardless of slight environmental shifts

Simple Application Instructions

• Measure your water volume and coffee grounds precisely before starting your brew cycle.
• Once finished, take a tiny sample of your liquid and pass it through a standard coffee filter to remove structural sediment, allowing the clear drops to rest directly on the main prism glass cover.
• Let the hot sample cool for approximately 30 seconds to allow the prism glass to balance temperatures cleanly.
• Look through the manual focus eyepiece directly toward a light source. You will see a distinct horizontal boundary line form where the top blue field and the bottom white field intersect. Read the aligned metric value, note your extraction level, and enjoy your perfect cup!
