The 洪堡 pocket penetrometer is a 8" penetrometer, 它使用了一个封闭的, spring-operated mechanism for fast estimates of unconfined compressive strength of cohesive soils. While the pocket penetrometer is used widely for checking consistency and providing quick indications of compressive strengths in the field, it should not be used to replace laboratory testing or extensive field analysis, nor should it be used to product foundation design data. It can also be used to accurately indicate consistency and approximate unconfined compressive strength of undisturbed Shelby tube cohesive soil samples.
The pocket penetrometer is specified f或使用 by OSHA for field personnel to verify soil strength estimates when evaluating stability and the safety of trench excavations. It verifies whether excavation side walls require shoring, based on OSHA cohesive soils classifications, 表示一致性, 抗剪强度, and approximate unconfined 抗剪强度. A pocket penetrometer is required by OSHA on all excavation jobs, and it can help protect you from costly lawsuits and construction delays.
The 洪堡 pocket penetrometer provides a direct-reading scale—in tons/ft2,或kg/cm2, which corresponds to equivalent unconfined compressive strengths. The H-4200 measuring range of 0 to 4.5吨/英国《uedbet官方网站》2 and the H-4200M measuring range of 0-45ton/m2.The penetrometer features high-quality construction with an anodized aluminum body and a stainless steel plunger. It also includes a belt-loop style carrying case and operating instructions.
