Schmidt OS-120 Low-Strength Rebound Hammer for Fresh Concrete and Brickwork Mortar Testing

Schmidt OS-120 is a rebound hammer intended for compressive strengths below 5 MPa. This stated range distinguishes it from general concrete rebound hammers and makes correct model selection important when the buyer’s material falls within the specified low-strength context.

One stated model supports fresh-concrete applications, including estimation of early strength development. Buyers should confirm the intended test procedure, correlation approach, surface preparation, age of concrete, and required interpretation method before selecting the applicable OS-120 configuration.

A second stated model addresses mortar applications and estimation of mortar strength in brickwork. The exact correlation, accessible test surface, masonry condition, and acceptance method are not specified and should be confirmed for the intended investigation.

The instrument uses a large half-circular scale described as high resolution. Exact scale divisions, impact energy, measurement units, operating orientation, conversion method, and data-recording accessories are not specified here and require confirmation before ordering.

Confirm whether the requirement concerns fresh concrete or mortar, and verify the applicable model, strength range, test method, calibration, accessories, carrying case, documentation, and service support. These procurement details are not fully stated in the product information.

FAQs

• What strength range is stated? The Schmidt OS-120 is identified for compressive strengths below 5 MPa within its fresh-concrete or mortar testing application.
