The Rudolph J357 Automatic Refractometer, designed as a research quality instrument offers one of the highest measurement ranges of any instrument in the Rudolph refractometer product line. This instrument offers the same extra wide refractive index measurement range as our chemical industry refractometer models combined with the high accuracy of our food industry refractometer models. It also offers very powerful automatic electronic temperature control (heating and cooling) and is able to make RI and BRIX measurements at up to 100 °C.

The J357 is a perfect choice for the most demanding pharmaceutical, chemical, petroleum, essential oils, fragrance and cosmetic refractometer users.
Simple Automatic Refractometer Operation
Operating the J357 Automatic refractometer is as simple as placing a sample on the artificial sapphire prism, closing the presser and reading the answer on the Digital Display — all in just a few seconds. There are no shadow lines to match and there is no eyepiece requiring any kind of operator determination or manual adjustment. When the “measure when stable mode” is selected, the J357 Refractometer automatically waits until the sample has been heated or cooled to a predefined temperature before initiating a measurement.
Automatic Refractometer – Interface Solutions
Rudolph allows the lab manager to select from different interface options because we understand laboratories and manufacturing floors have different needs when it comes to the information required for monitoring a process.
