Automatic Transmission Colorimeters: PFXi-195 Series
Lovibond PFXi-195 Series is a family of automatic transmission spectrophotometric colorimeters engineered for precise, repeatable, objectie color measurement of transparent liquids. Engineered for laboratory and industrial environments, the PFXi-195 Series eliminates subjective visual assessment and ensures compliance with international colour standards.
Using spectrophotometric transmission measurement, the PFXi-195 Series analyses light passing through a liquid sample to deliver precise colour values independent of operator or lighting conditions. Integrated RCMSi remote calibration technology ensures long-term accuracy, traceability, and reduced instrument downtime.
