“I used Klonk Image Measurement as a solution to measure poly lines in the roots of (Arabidopsis thaliana) plants for a stress experiment where different things like salt were introduced and the growth was recorded ect. They grown vertically in an agarose gel medium in a petri dish and I needed a depth measurement and looked for something more precise than a standard linear metric ruler. I was able to scan the petri dishes with the plants sealed inside for an accurate measurement while maintaining a sterile environment, over the entire growth cycle open the image in Klonk, then measure at my convenience. Then that data was plugged into excel and graphed for comparison to the control for growth of the roots. I was working as an intern volunteer for a genetics research lab at University of New Mexico, (with PhD Olga Pontes team), small interfering RNA (siRNA) directing DNA methylation, (switching sections of the DNA on and off) relating to cancer research in animals and drought resistant agriculture. My opinion of Klonk is that is a great measurement solution and is very easy to use, I was glad to have found it. The light version did not allow you to, “save as” a picture displaying the measurement lines but I guess you have to purchase that feature. Tell the team thank you for making a good and useful program for the lab, I would recommend it, and certainly do when something like this is needed.”

“I very much enjoy the KLONK Image Measurement Light software. I use it to measure various dimensions of plants (true length as opposed to height, width, and surface area of filiage) in my research on biopolymer eps substances. The ability to calculate surface area is of significant benefit to my studies.”

Tom Larson MD – Larson Growth Industries – “Greener Science and Better Results.”

“Looking for a program on the internet to measure images, I found “KLONK Image Measurement Light”. I was amazed by its simplicity! It was exactly what I needed to measure perimeter, diameter and area of selected portions within a photo. Best of all, they provide a very high quality program for image measurements which is available for download and use free of any charges. I am now acquiring the scientific version. I strongly recommend KLONK!”

“What i did was to take picture of some wounds, where i placed a ruler close to the wound, and then measured the size of the wound with the KLONK software. I made it work without any problems, and I did not need any instructions. So the software is user friendly. I recommend to measure wound sizes on a regular basis. It should be done a lot more than it’s done today.” 

Arne Langøen, Chairman of Norwegian Woundcare association (NIFS)

“I have used KLONK Image Measurement Central as a measuring device for evaluating and documenting changes in wound sizes in treatment of cancer wounds. The software has given me the opportunity to evaluate the impact of the treatment down to mm2 precision of wound sizes, and I have by that been able to work with great precision. The software has furthermore given me the opportunity to get an overview of the wounds progress with graphs that describe the development of e.g. the degree of necrotic tissue over time. The functionality of the software has been consistent with my needs, and I have been satisfied with using it both as a tool for clinical use and in research.”
