The Waldfreund forestry measuring clamp has been specially developed for measuring the diameter of logs lying on the ground. The triangular profile, which is easy to lay on, enables easy reading from above. The caliper, made of impact-resistant polyamide, glides easily and smoothly over the measuring rail without jamming. The special laser-engraved printing process makes the numbers easy to read even in twilight, and an anodised layer 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 three lengths. Also available with French pitch on request.
