High-performance Field and Laboratory Chlorophyll Fluorometer
Fitting routine for the fast fluorescence O-I1 to determine the functional absorption cross-section of the PS II antennae (Sigma) needed for the determination of PS II-specific electron transport rates
Fitting routine for exponential decay (e.g. QA– reoxidation after a single turnover flash) or rise of a signal with up to three exponentials
Choice of two fitting routines for light curves (determination of cardinal points α, Ik and ETRmax)
Ft, F0, FM, F, F0' (also calculated), FM'. Fast polyphasic rise and decay kinetics (time resolution up to 10 µs). PAR using Spherical Micro Quantum Sensor US-SQS/WB or Mini Quantum Sensor US-MQS/WB
F0' (also measured), Fv/Fm and Y(II) (maximum and effective photochemical yield of PS II, respectively), qL, qP, qN, NPQ, Y(NPQ), Y(NO) and ETR (electron transport rate), C/F0 (constant fraction of F0 that is assumed to originate from PS I)
Aluminum box with custom foam packing
Round stainless steel cuvette (7.5 mm wide, 9.0 mm deep) with top window adapter for connecting the fiberoptics; embedded in PVC body with injection port for Hamilton syringes and hose nozzles for connecting an external flow-through water bath (not included). Including three 6.0 x 1.5 mm magnetic stir bars
Aluminum plate (6.0 x 3.3 cm max.) with 11 mm diameter circular hole (measuring area) and aluminum port to position fiber at an angle of 60° relative to the aluminum plate. With port for temperature sensor of 2060-M unit to measure surface temperature and thread to mount the PAR sensor of the 2060-M unit. Connected to a 10 x 0.8 cm (L x Ø) steal rod with two lateral plastic supports (12 cm x 1 cm x 1 cm, L x W x H), which are lockable by knurled screws
90 cm cable with fuse for over-current protection. The cable bypasses the internal battery of the PAM-2500 fluorometer and supplies voltage from an external 12 V battery directly to the electronics. External DC cable to connect 12 V battery. One red and one black (GND) blade receptacle at one end, the other end with special PAM-2500 EXT. DC plug.
