All PTR-300 models operate over the wide refractive index (RI) range of 1.32 to 1.68. The PTR-300 provides an accuracy of 1 in the 4th decimal place of RI over the full range. The PTR-300X model gives an enhanced accuracy to 5 in the 5th decimal place of RI over the range 1.32 to 1.45, with only slightly reduced accuracy to 1.68 RI. Index Instruments. Index Instruments have been making refractometers since 1975 and offer a wealth of experience in this specialised field of scientific instrumentation. We spend a high portion of our turnover in a programme of continuous reseach and development to improve and innovate our products. For higher accuracy see the PTR 2X. All PTR refractometers are supplied with a hinged cover, which insulates the sample and excludes ambient light. Optionally, the PTR can be supplied with various cells that have been designed to provide rapid, convenient semi-automatic or automatic sampling while maintaining analytical accuracy and thermal stability.

A simple key press gives access to up to 14 scales; refractive index (RI), Brix (% of sucrose), temperature corrected Brix, temperature corrected RI, and up to 10 user programmable scales. Working with a leading manufacturer of contact lenses, Index Instruments have developed the CLR 12-70 fully automatic refractometer. This instrument will allow you to measure refractive index, water, or solids content of gas permeable and soft contact lenses. The CLR 12-70 measures clear or colored iris lenses with equal ease and accuracy.
