Because only the best will do.
High-precision sapphire optics, the next hardest substance to diamond, provides a virtually scratch-proof measuring surface. With 4x the thermal conductivity of ordinary glass prisms, sapphire also improves the speed and accuracy of temperature correction. So why do competing refractometers use glass prisms?
Extensive Scale Library
The Palm Abbe refractometer can be factory programmed with tens of thousands of scale combinations from the most extensive refractometer scale library on the planet. What is a Scale? Think of it as a special program that converts refractive index into your measurement units of choice, for your particular fluid. Scales do the conversion work, so you don’t have to.
Never Used a Refractometer?
It’s ridiculously easy.
The Palm Abbe refractometer is fast, convenient, and easy to use. The user interface consists of two buttons, one to take readings and the other to step through various menu options.
Simply place a drop or two of fluid in the stainless steel well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout in your selected unit of measure. Nonlinear temperature correction is automatic and ensures that fluids are measured accurately.
In most cases, The MISCO refractometer automatically calibrates itself to water and is ready to use in seconds. No screws to turn and nothing to adjust.
How Does a Digital Refractometer Work?
Inside the OPTICAL-ENGINE, light from a high-intensity LED is focused from beneath onto your fluid, sitting on the sapphire measuring surface in the refractometer’s stainless-steel sample well. Depending on the refractive index of the fluid, some of the light is lost into the fluid and some is reflected towards the high-definition detector array. The position of a shadow-line projected onto the detector array is directly related to refractive index. The reading is converted into refractive index, temperature corrected, and then automatically converted into the unit of measure that you selected.
