The Waldmeister forestry caliper is the classic among the measuring clamps for determining trunk diameters. Thanks to the practical and robust design with oval profile, the caliper slides over the measuring rail without jamming. The special printing process of the scale makes the numbers easy to read even in twilight and an anodised coating reliably prevents abrasion. At the same time, this ensures easy cleaning of resins and dirt. The special alloy makes the dial extremely rigid, robust and resistant. Available as standard and "calibrated" version in four lengths. Different graduation patterns are also available on request.
