Handy FluorCam FC 1000-H is a lightweight, portable device designed for time resolved chlorophyll ?uorescence imaging of leaves, small plants, leaf segments, mosses, lichens, seeds, roots, tissues on plates or algal colonies both in a field and laboratory. The typical size of an investigated object is up to 41.5 × 31.5 mm. Handy FluorCam is a compact instrument consisting of a CCD camera and four fixed LED panels, one pair supplying the measuring pulses and the second pair providing actinic illumination and saturating ?ash. Handling of larger leaves (e.g., tobacco) is simplified if an additional leaf clip with gentle lock/release mechanism is mounted. The Handy FluorCam FC 1000-H is an easily portable system, it can be powered from the power supply or it can run on batteries provided in  a convenient bag carried on the shoulder.

Double-Modulation Fluorometer FL 6000 measures chlorophyll α (Chlα)- -?uorescence. Measured ?uorescence emission is excited by a set of light- -emitting diodes that generate measuring ?ashes of few microseconds in duration and low intensity; the photochemistry is driven by single-turnover ?ashes or by continuous actinic irradiance. Chlorophyll ?uorescence is detected by a PIN photodiode and digitized by a 16-bit A/D converter. The instrument supports Pulse Amplitude Modulation measurements and, at the same time, can capture fast OJIP transients or perform rapid measurements of QA- reoxidation kinetics, S-states.

Algae Online Monitor (AOM) is a portable and robust device for online detection and continuous monitoring of photosynthetic microorganisms in both natural and artificial water bodies. It detects variety of cyanobacteria, green and brown algae, diatoms, and other microbes.

The FluorPen FP 110 is a portable, battery-powered PAM fluorometer that enables quick and precise measurement of chlorophyll fluorescence parameters in the laboratory, greenhouse, or in the field. It can be effectively used for studying photosynthetic activity, stress detection, herbicide testing, or mutant screening. The affordable price and straight-forward two-button operation makes the FluorPen a perfect tool for research and for teaching photosynthesis. The PAR-FluorPen FP 110 is an extended version of FluorPen FP 110 that incorporates an integrated light meter for direct digital readouts of Photosynthetically Active Radiation (PAR) in the range from 400 to 700 nm.
