Based on very satisfying results, we decided this year to replace also the backup Abbe style instrument by a second Rudolph refractometer. We are very pleased with your instruments; you can consider us as reference customer.
The J257 refractometer, which we recently purchased from Rudolph, has been a valuable addition to our laboratory. It has provided us with consistent and accurate readings for both research and production.
We purchased two J257 Automatic Refractometers …Those instruments not only supply critical data in the creation and optimization of products, but they often do so as many as seven days a week. The ability to make fast, accurate and reliable determinations of refractive index in just a matter of seconds allows us to maximize the quality of our products.
I would highly recommend the Rudolph J57HA Refractometer over any other brand of refractometer that I have used or tested throughout my many years working in the sugar industry…
…I have been extremely pleased with the Autopol (Polarimeter) instruments over the years…As expected, our refurbished Autopol II has been reliable and easy to use. I should add that your personal visit to help us set up the instrument was very helpful and illustrated to me that Rudolph Research stands behind its products.
