From the company that brought you the Goldberg TS Meterthe industry standard The Reichert TS Meter-D is the first clinical digital, handheld refractometer that performs as well as most laboratory-grade refractometers. Yet it offers the ease of use and price of a handheld. Its designed to automatically read samples with precision comparable to high-end automatic refractometers. Operator interpretation of unclear shadowlines is no longer necessary. New sapphire prism for greater durability and accuracy The TS Meter-Ds new sapphire prism delivers 2.5x more conductivity to temperature than a conventional glass prism, providing greater accuracy of the Automatic Temperature Compensation (ATC) calculation. The result? A more precise measurement every time! 4x harder than glass, the sapphire prism is resistant to demanding applications, providing lasting durability and service over the life of the refractometer. Measure different samples with just one instrument A wide reading range (better than twice that of any competitive instrument) enables the use of just one instrument to measure different samples. The best-in-class accuracy of ±0.0001 Refractive Index ensures the right result every time. PC connectivity for transfer of measurements and programming of scales Optional IR Communications Package enables reading log, calibration log, and custom scale transfer to any lab PC.
