For the holing out test we use a holder manufactured in-house. Read here the instructions for use.<\/a><\/p>\n

Accompanying film (YouTube)<\/a> made on GB De Turfvaert, shows how it works.<\/p>\n

Here is also a report of 4 American universities<\/a> on a comparison of the stimpmeter and the Pelzmeter, which shows that the results of both devices are reliable and comparable:<\/p>\n

Barenbrug is developing a system that automatically recognises grass species. DGB members are currently helping to populate the database. The photos are taken with your own smartphone placed on a flower pot. Dimensions 15x15x15 cm. The wooden blocks are for a stable position and always the same. Make sure there are no cracks through which light can enter. Take the photos with the flash turned on. Take at least 15 photos when the grass is dry (to prevent reflection)<\/p>\n\n\n
