The K-1 is designed for measuring CRT's. It is also designed to measure projection displays. It does not matter what projection technology is used: LCD or CRT, DLP or LCoS, the K-1 can handle it.

Klein K-1 Colorimeter Probe

with FFT Flicker Meter Measuring & Gamma Testing

The Klein K-1 tri-stimulus CIE Colorimeter Probe is designed to be the best colorimeter in sensitivity, stability and speed. It attaches directly to a pc's serial com port (RS-232), and runs with the companion pc program. Whether a desktop or a laptop is used, the Klein measurement application is in control and many additional features are available.

• Large Photodiodes. Diodes that are 5mm x 5mm each, along with thermally stable components, are combined to report the highest degree of accuracy.
• Exceptionally Accurate Filters. Not only is the f1’ of Y critical but the accuracy of X and Z as well. See the actual Klein vs CIE graph, on the technical page.
• Light Mixing Chamber. This ensures all the diodes see the same light and virtually eliminates any x,y variations by turning the probe clockwise or counter clockwise.
• Quick Measurements over an RS-232 line. The K-1 head takes 256 measurements per second, even at very low light. For readability, 8 measurements per second is displayed.
• FFT Flicker Meter. Probe measures & integrates Y data in the head, and streams in real time to the pc, and a Fast Fourier Transform is performed. JEITA method.
• Gamma Testing. Luminance measurements are taken from 100% video to 0% video in 10% increments. Y gamma is displayed along with the data and graphs.
• Klein pc Program. Create calibration files & set measuring parameters. Then data log, graph and export. The pc program manages the data in an easy to use interface.
• Rugged Construction. The K-1’s auto ranging is solid state and the case is impact resistant to hold up to 24 hours a day, 7 days a week required usage that manufacturing plants require.
• Included items are the the pc program and a certificate of calibration
