3050-F

Accessory

Fiberoptics PAM-Fluorometer

The long lasting experience in PAM fluorometry of Heinz Walz GmbH is embedded in the PAM fluorometers 3057-FL and 3050-F.

To analyze fluorescence in ambient light, the Fiberoptics PAM-Fluorometer 3050-F can be attached to the Standard Measuring Head 3010-S. It employs a blue LED for measuring light and the saturating light pulses, and also features far-red illumination for F₀’ determination.

The Fiberoptics PAM-Fluorometer 3050-F can be directly operated with the GFS-3000 in the field.
