MONITORING-PAM Multi-Channel Chlorophyll Fluorometer Long-Term Monitoring of Chlorophyll Fluorescence under Field Conditions

MONITORING-PAM Multi-Channel Chlorophyll Fluorometer Measurements of chlorophyll fluorescence give easy and non-invasive access to primary photosynthetic productivity data. In particular, pulseamplitude modulated (PAM) chlorophyll fluorescence, in combination with saturating pulse analysis of fluorescence quenching, has become a key technique in basic and applied photosynthesis research. With the introduction of the PAM-101 chlorophyll fluorometer in 1985, by Heinz Walz GmbH, the Walz company has made PAM fluorometry generally available to the scientific community. While this first system...

System Components & Descriptions Pulsed Excitation Light MONI-HEAD/485 Measuring Head The MONI-HEAD/485 measures both ambient light remitted by a scattering Teflon sheet to a PAR sensor inside the instrument and modulated fluorescence excited by the pulsed measuring light emitted by the measuring head. Ambient Light Front View MONI-DA Data Acquisition system The MONI-DA is hermetically sealed. Settings are adjusted using magnetic proximity switches. Data are stored on a 1 GByte memory size microSD flash card. Magnetic Finger in Home Position During Measurements On (system wake-up)...

(►) Example of Application Fluorescence monitoring in the field. Data from Scots pine needles were recorded at the beginning of spring (left-handed panels) and at the beginning of summer in Finland (righthanded panels; data from Porcar-Castell et al. (2008) Photosynth Res 96, 173-179). Typical Areas of Applications • Above-ground and marine eco-physiological research. Crop plant monitoring in precision farming. • Continuous monitoring and long-term estimation of primary photosynthetic production. • Detection of sustained nonphotochemical energy quenching during long-term stress periods.

WinControl-3 Software General Features and Graphical User Interface General Features The WinControl-3 software represents the latest version of the WinControl software family. Presently, WinControl3 operates the JUNIOR-PAM and the MONITORING-PAM fluorometers. Different from its predecessors, WinControl-3 handles simultaneously multiple PAM fluorometers and permits very long periods of data acquisition. Data Evaluation Saturating pulse analysis with automatic detection and calculation of standard fluorescence parameters including Fo, Fm, Fo’ (calculated), Fm’, Fv/Fm, qP, qL, qN, NPQ, Y(II),...

Measuring Head MONI-HEAD/485 • Housing: Water-tight aluminum cylinder (stainless steel on request) with one end featuring a collimating lens for focusing measuring light, actinic light and saturating pulse light on the sample and collecting fluorescence • Sample Clip: Consisting of 2 aluminum frames (35 x 25 mm), pressed together by a special O-ring, and mounted at a distance of 25 mm from the MONI-HEAD/485 optical window. Angle between optical axis of the MONI-HEAD/485 and sample clip plane: 120°. Data/power cable: 10 m standard length (MONI-HEAD/485 to MONI-IB4/USB or MONI-HEAD/485 to...
