MISCO Refractometers provide precise metalworking fluid (MWF) concentration measurements to maximize feed and speed rates, reduce surface finish problems, and reduce tool wear and skin problems. Palm Abbe™ Digital Handheld Refractometers are easy-to-use, providing twice the precision of competing digital refractometers while eliminating the subjectivity of reading shadow lines in "spyglass-style" analog refractometers. For continuous fluid monitoring, the IRIS™ Inline Process Refractometer is easy to install on machine sumps and connect directly to a PLC or data capture system. All digital handheld and inline units can be custom programmed with fluid-specific scales to eliminate the need for manual fluid factor conversions. A world leader in the refractometry field for 70 years, MISCO products are made in the USA in Solon, Ohio.
