Gilson Company, Inc. Gilson Concrete Test Hammer HM-71

Description
Concrete Test Hammers are ideal for fast, inexpensive, nondestructive estimations of in-place concrete strength. Hammer tests can help determine where test cores should be taken and locate damage from freezing or fire. Useful range covers concrete strengths from approximately 1,400-8,000psi (10-55mPa). The plunger rod is pressed against a concrete surface until a spring-loaded mass is released, causing an impact on the concrete. Rebound of the mass is registered on the instrument as the “rebound number”. Included calibration curves provide estimated strength from rebound number, but accuracy is greatly improved by user-produced laboratory correlations with compression tests on the same type of concrete being evaluated. HM-71 Gilson Concrete Test Hammer is an economical alternative that meets all published specifications for these devices. This Made-in-America unit gives consistent results and reliable operation identical to brand-name units. A durable nylon carrying case with loop handle, carborundum stone for surface preparation, instructions and charts are included with the HM-71. Est. Ship Wt.: 6lb (3kg). HM-75 Schmidt Concrete Test Hammer is manufactured by the original producer of these instruments. It is supplied with a plastic carrying case, charts, instructions, and carborundum stone for surface preparation. Est. Ship Wt.: 6lb (3kg). HM-101 Schmidt Recording Concrete Test Hammer automatically records rebound numbers as a bar chart on a paper strip. Each strip chart will log up to 4,000 impacts. HM-101 is supplied with a carrying case, paper charts and grinding stone. Dimensions with case: 11.6x12.8x4.1in (295x325x105mm), WxDxH. Est. Ship Wt.: 7lb (3kg). HM-76B Concrete Test Hammer Calibration Anvil can be used to check the calibration of concrete test hammers after every 1,000-2,000 impacts. The HM-76B has a solid steel 6in (152mm) diameter anvil with a hammer guide and hardened alloy steel rebound plate. A hardness certification to ASTM E 18 requirements is provided. A wire brush for cleaning is included. Est. Ship Wt.: 40lb (18kg).
