Digital refractometer
J357
Rudolph Research Analytical
J357 AUTOMATIC REFRACTOMETER
Designed as a research quality instrument the J357 has the highest performance of any refractometer in the Rudolph range. This instrument offers the same extra wide range as our chemical industry refractometer models combined with the high accuracy of our food industry refractometer models. It also offers the most powerful temperature control and is able to measure at up to 120 °C.
Operation
Operating the J357 is as simple as placing a sample on the artificial sapphire prism, closing the presser and reading the answer -- 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 automatically waits until the sample has been heated or cooled to a predefined temperature before initiating a measurement.
