MINI-PAM-II

Sensitivity, small dimensions, reliability under rugged conditions, and simple execution of fluorescence analysis make the MINI-PAM-II the standard for PAM fluorometry in field research. The device's multifaceted accessories, including the recently developed Porometer leaf clip and the highly sensitive oxygen probe for suspension applications, enhance its versatility and facilitate the acquisition of highly informative data. 

Energy-efficient LED sources, storage capacity for 27,000 data sets, and easy replaceable off-the-shelf batteries permit extensive measurements in remote places. A sun-readable touchscreen serves as easy-to-use interface for field studies. The fluorometer automatically calculates and displays all relevant parameters of saturation pulse analysis. Depending on the main application, the MINI-PAM-II is available as red or blue version. 

The far-red light (735 nm LED) of the MINI-PAM-II preferably excites photosystem I. Low intensity far-red light induces nearly no charge separations in photosystem II. A special measuring routine uses this far-red light to determine the F₀’ fluorescence level, which is important to correctly assess the redox state of photosystem II reaction centers.

Expandable through accessories such as various leaf clips, external multi-color lamp, miniature spectrometer, suspension cuvette, optical oxygen sensor, and barcode scanner. In experiments using the internal actinic light source, the light intensity at sample level can be monitored online using an internal light sensor. This internal sensor must be calibrated against an external light sensor.

The MINI-PAM-II system offers a range of powerful accessories designed to broaden its application across diverse research settings. The MINI-PAM-II/POROMETER leaf-clip enables combined measurements of stomatal conductance and chlorophyll a fluorescence, making it ideal for rapid stress screenings, field studies, and detailed plant analysis - all within a compact, GPS-equipped device that delivers stable results in under 15 seconds.

For suspension-based work, the Suspension version of the MINI-PAM-II using the KS-2500 cuvette paired with the MKS-2500 stirring unit allows simultaneous fluorescence and oxygen measurements in just 400 µl of sample, with optional temperature control via a connected water bath. Together, these accessories make the MINI-PAM-II a flexible and comprehensive tool for both laboratory and field-based photosynthesis research.
