MISCO Palm Abbe Digital Handheld Refractometers and Inline Process Refractometers provide precise field testing of both Type I & Type IV deicing and anti-icing fluids, jet fuel, and glycol recycling. MISCO refractometers are custom programmed with specially developed aircraft deicing measurement scales for improved testing precision. NIST-traceable certificates of calibration are also available, and the company's testing laboratory provides annual re-certifications and analytical viscosity testing of Type IV fluids.
