Manufacturer product document for the model and configuration named in the title.
View resource →Product overview
The Lovibond® PFXi 195 Series comprises automatic benchtop colorimeters for transparent liquids. The instruments display industry colour scales, CIE values and spectral data directly, reducing variation associated with visual assessment in laboratory quality control and industrial production.
Key features
- Nine interference filters with a spectral range of 420–710 nm.
- USB, LAN and RS-232 interfaces with storage for more than 100,000 readings.
- Single-key automatic baseline calibration and a measurement time of less than 30 seconds.
- Integrated industry colour scales, CIE values and spectral data, with colour-scale upgrades available when required.
- Calculation and description of off-hue status to help assess how closely a sample matches the selected scale.
- Removable steel sample chamber for cleaning and maintenance, with rugged steel construction for laboratory and production environments.
- Windows colour-control software for data analysis and remote instrument operation.
