Heinz Walz GmbH has been serving science for more than 40 years with sophisticated measuring devices for plant research. Technical progress in LED technology and other electronic components allows us to design instruments with unprecedented analytical potential. These novel devices again drive progress in science.
The DUAL-KLAS-NIR represents a significant advancement over the well-established DUAL-PAM-100 system. The DUAL-PAM-100 employs one pair of wavelengths in the near infrared (NIR) to measure absorption changes related to redox alterations of the photosystem I reaction center. Using four wavelength pairs in the NIR, the DUAL-KLAS-NIR is capable of...
Chl Fluorescence & P700 AbsorbanceWALZ P700 Tutorial - Basic Concepts:
The GFS-3000 is a portable, high precision system for the assessment of plant photosynthesis (CO2-uptake) or respiration (CO2-release) and transpiration – in combination with optical measurements.
Chlorophyll Fluorescence System WALZMOBILE Version is dedicated to chlorophyll fluorescence imaging in the field. The MAXI and MINI versions may be combined with the Gas-Exchange System GFS-3000 thus integrating detailed spatial information on photosynthesis and with exact analysis of photosynthetic carbon fixation. OUTDOOR Version:For field research on...
The leaf clip JUNIOR-BD allows measurements of ambient light intensity and leaf temperature as complementary information to fluorescence data.The clip holds the leaf at constant distance to the fiber tip and at an angle of 60° between fiber axis and leaf plane.Photosynthetically active radiation, (PAR light), in μmol m-2 s-1is measured by a micro quantum...
JUNIOR-PAM and JUNIOR-PAM/W - Compact Fluorometer from WALZ The two versions of the JUNIOR-PAM fluorometer provide visible light of different spectral composition: the BLUE version emits between 400 and 500 nm with a maximum around 445 nm. The WHITE version shows a narrow-band blue emission peaking around 445 nm plus a broad band emission ranging from 475...
The suspension cuvette includes a 400 μL stainless steel sample compartment with a PVC exterior.
The LS-C sensor uses a plastic diffuser to obtain an angular response error of less than ± 3% (-30…30 ° angle).
A MICRO-PAM system involves several light-weight chlorophyll fluorometers for field use. Being capable of multi-site monitoring of photosynthesis over weeks and months, the MICRO-PAM is tailored to study plant responses to environmental changes in nature and under controlled conditions. Due to its compact measuring heads, the MICRO-PAM is suited for...
Outstanding Properties of the MICROSCOPY-PAM◆ Fluorescence detection by a highly sensitive red-enhanced photomultiplier tube◆ Single cell analysis◆ Version with blue or red light available
◆ FSO2-II FireStingO2 (1-Channel) and FSO2-AK Interface Converter for FireStingO2 for MINI-PAM-II◆ The FSO2-II is an improved version with robust probe for fast measurement, designed photosynthetic measurements.
The MINI-PAMII/POROMETER is a new leaf-clip for the MINI-PAM-II for combined measurements of stomatal conductance and chlorophyll a fluorescence. It measures water evaporation and stomatal conductance of plant leaves and needles to determine stomatal function, which is strongly influenced by stress factors acting on the plant. ◆ Numerous sensors: humidity...
