The process photometer ZPM measures the transmission of optical transparent materials like silica, glass, crystal, or plastics plates.
The influence of ambient light is minimized by using a modulation technique. This is of special importance for the measurement of scattering samples.
Yoke photometers measure at a fixed wavelength between 254 nm and 980 nm or with selectable wavelengths, for example, red (630 nm), green (520 nm), and blue (470 nm) for ZPM RGB. Our range includes more than 30 wavelengths; thus, the photometer can be optimally adapted to the application.
Transmission data are steadily shown on the display. Measuring data can be read by a computer or PLC (optionally) manually or after being triggered.
The device under test can be adjusted and fixed using the optional alignment table. We also manufacture individual yoke photometers for scattering samples or custom sizes. You can take advantage of the modular base unit and our in-house CAD-CAM production.
