1. Purpose and Characteristics
The HM-40 type post anchoring concrete strength tester is used to test the strength of concrete and the bonding strength between decorative bricks, mosaics, and walls or floors in construction projects.
The HM-40 type post anchoring concrete strength tester is a small hydraulic force measuring device that uses the post anchoring method to measure the strength of concrete by measuring the force required to pull out the anchoring component placed inside the concrete. When testing the bonding strength of materials such as decorative bricks and Marcel, the tensile force generated by the three point reaction support on the bonding material of the decorative bricks is used to determine the strength. This instrument is composed of components such as a through center jack, a hand pump, a triangular chassis, and a force measuring device. It has the characteristics of dual use, novel structure, compact size, convenient operation, and complete functions. The HM-40 type post anchoring concrete strength tester adopts manual loading for the oil pump, which has small driving torque, comfortable and reasonable shaking direction, continuous and uniform loading, and stable performance.
The HM-40 type post anchoring concrete strength testing instrument adopts a microcontroller as the core intelligent data processor, and the internal battery is rechargeable. It has functions such as Chinese display, zero clearing (which can eliminate measurement errors caused by friction in the hydraulic system), peak holding, storage, and automatic shutdown.
