The MULTI-COLOR-PAM-II is the first Walz instrument with a time resolution of less than 1 µs. It is also the first Walz instrument with which the kinetics of single turnover flashes can be measured.

We are pleased to announce a new distribution partnership with Plant Science Brasil Ltda. Effective July 1st, 2024, Plant Science Brasil will become the exclusive distributor of Heinz Walz GmbH products in Brasil.
Plant Science Brasil Ltda, located in Piracicaba, São Paulo State, was established to meet the needs of researchers and customers in plant physiology, soil physics, and environmental monitoring. The company boasts an experienced and dedicated team, supported by partners that enable it to offer comprehensive support, maintenance, and technical assistance to all Brazilian customers.
Leading the commercial efforts of Plant Science Brasil is Felipe Defavari, a Forest Engineer with 15 years of experience in the Brasilian market. Felipe specializes in instrumentation solutions for plant physiology, ensuring that Plant Science Brasil can effectively meet the specific needs of scientists and customers alike.

"We are honored to start working with WALZ, a renowned manufacturer of high-quality instrumentation for plant science," said Felipe Defavari, Commercial Director of Plant Science Brasil. "Our team is committed to upholding the highest standards of service and support for our Brazilian customers."

The new LEAF-STATE-ANALYZER LSA-2050 is a handheld device for non-invasive leaf analysis. This device provides a picture of stress effects and a plant's ability to cope with stress.

From January 2024, WALZ partners with scientific approved company Green Spectrum Technology from New Delhi, India. Green Spectrum Technology Pvt. Ltd. has a highly qualified and experienced team to serve our high quality photosynthesis instruments for Plant Science, Environmental Science and Climate change studies.
Mr. Ravi and Dr. Sanjay are biotechnologist with 15 years of experience in Plant & Environmental Science. Dr Sanjay published papers (more than 650 citations) in most of the renowned journals of the world and is having 10 years of experience in Plant Science Research.

WALZ is proud to start that partnership to fulfill the needs for measuring instruments for Plant Science, Environmental Science and Climate change studies.
The partnership includes sales, service, research and application support. For further information please contact info@greenspectrum.co.in or info@walz.com.

The tutorial shows the technical and practical aspects of fluorescence measurements with the MINI-PAM-II.

For the first time we participated in the “Lange Nacht der Wissenschaften” in the Botanical Garden, Erlangen.
With our instruments we provide scientists with valuable information on optimizing growing conditions, the health of their plants, herbicide resistance, algae population in lakes and much more. The participants were able to conduct short experiments with our devices. A very exciting evening for the participants and WALZ.

We have spent a great time with our distributors from China, South Korea, Taiwan and Japan.

Employing the AQUATIC Version of the MONITORING-PAM to better understand the impact of environmental changes on coral reef organisms. A research site investigating photosynthesis of coral endosymbionts in the Red Sea is now sending live data and a video stream.

In a first tutorial the principles of fluorescence measurements were explained. The present tutorial focuses on the structure and features of WinControl-3 software and on aspects of some of the major experimental applications of this software. WinControl-3 is used by the following instruments: MINI-PAM-II, DIVING-PAM-II, WATER-PAM-II, MONITORING-PAM, MICRO-PAM, MICROSCOPY-PAM and JUNIOR-PAM.

The scope of MICRO-PAM systems has been extended by the newly developed measuring head with amber LED, the MICRO-HEAD/3A. The emission properties of the novel PAM fluorometer is particularly suited to probe cyanobacterial mats and lichens, or crusts containing cyanobacteria.

The new HEXAGON-IMAGING-PAM represents the largest WALZ Imaging System available. Despite the large measuring area, the instrument is still flexible enough to measure a wide variety of samples. These include individually potted plants, seedlings in larger plant trays, or harvested samples of higher or lower plants. It can measure areas of 20 x 24 cm with a resolution of up to 1000 x 1200 px (2x2 binning), according to the PAM principle with highest accuracy.

The Porometer leaf-clip is an accessory for the MINI-PAM-II. It combines measurements of PAM-fluorometry with the analysis of stomatal conductance. Gain new insights with the MINI-PAM-II/POROMETER for rapid screenings, high-throughput stress evaluation, or detailed plant analysis using well-established protocols like induction-curves or light-curves. As a lightweight, compact device, it is ideally suited for use in the field as well as in greenhouses and laboratories.

First time as an exhibitor at the fair in Forchheim. A few impressions of an exciting day with our trainees.

In the 2023 article of Ulrich Schreiber in Photosynthesis Research the reader gets more information about the presence and role of variable photosystem I fluorescence. Using the full potential of the MULTI-COLOR-PAM, he dissects again the O-I₁-I₂-P kinetics of saturation pulses.

For the study of photosynthesis, non-invasive photosystem-I probing P700 measurements are not only a valuable tool in their own right but even more so in combination with fluorescence measurements. This tutorial, tries to give the viewer a basic understanding of the method, the tools used and some examples of applications of P700-measurements in photosynthesis research.

In 1972, Heinz Walz started his firm as a one-man enterprise with support of his wife, Hannelore, who took care of the unavoidable small business demands. Besides his professional qualifications as master craftsmen and electrical engineer, his chief start-up capital was a patented concept for measuring photosynthetic CO₂ uptake by plants [1]. Its essential characteristics were a flow-through measuring chamber and the evaluation of the CO₂ difference between the gas passing through the measuring chamber and the gas of a reference line. In short, Heinz Walz had the design of today’s high-performance gas exchange machines in mind. Before that, plant photosynthesis was mostly measured in closed chambers by metering the CO₂ added to compensate for plant CO₂uptake.
