MINI-PAM-II Photosynthesis Yield Analyzer WALZ

The new MINI-PAM-II fluorometer combines the merits of its predecessor “MINI-PAM” with most modern LED and computer technology.

Sensitivity, small dimensions, reliability under rugged conditions, and simple execution of fluorescence analysis makes the MINI-PAM-II the new standard for PAM fluorometry in field research.

Well-tested fiberoptics with 5.5 mm or 2 mm active diameter reaches even hidden samples.

Measurements under field conditions are easily controlled and monitored by a transflective touchscreen.

Energy-efficient LED sources, storage capacity of 27,000 data sets, and easy replaceable off-the-shelf batteries permit long term research campaigns at remote places.

A new fully digital leaf clip combines fluorescence analysis with measurements of photosynthetically active radiation (PAR), leaf temperature and relative humidity.

Optoelectronic Unit
