IIDomestic colorimeterNR145main features

1Automatically compare the color differences between the sample and the inspected item, and outputCIE_LabThree sets of data and △ after colorimetric analysisE△L△a△bFour sets of color difference data, providing reference schemes for color matching.

2It has two measurement modes: sample and single measurement, which meet the needs of measurement in different places, with simple operation and accurate measurement.

3The instrument is portable. There are two power supply methods: battery and external power supply, which are convenient and practical.

4Installed withUSBThe extension interface can be connected to a computer for display.
