J157 PLUS Bench Automatic Refractometer
Manufacturer: Rudolph Research Analytical
SKU: Inquire
Description
The J157 PLUS from Rudolph Research Analytical is a bench-top digital refractometer built for reliable performance in both laboratory and industrial settings. It provides rapid refractive index measurements, typically in less than three seconds, with a high resolution of ±0.00001 RI (or ±0.01 BRIX). The instrument operates across a refractive index range of 1.33 to 1.53 and can control sample temperature from 4°C to 95°C. Developed in consultation with users from various fields, it is designed to meet demanding application requirements. Its straightforward operation and robust construction make it suitable for quality control and research tasks where consistent, accurate readings are essential.
