The roll hardness tester is an analog measuring device to determine concrete strength. The measuring method of the roll hardness tester is based on the Schmidt principle. With this measuring method, a kinetic impact energy hits the concrete from the roll hardness tester. The resulting rebound enables the roll hardness tester to determine the strength of the concrete.

• Nominal kinetic energy: 4.5 J
• For high-strength concrete
• Simple and quick operation
• For determining concrete hardness
• Schmidt principle

PCE-HT-225A is a heavy-duty roll hardness tester or concrete test hammer, also called a paper roll rebound hammer or Swiss hammer, used to measure surface hardness and material compression strength. Suitable for use with rolled paper, concrete, rock and building materials, this rugged, manufacturer-calibrated rebound hammer is both easy to use and built to last.

PCE-MMK 1 is a portable handheld digital moisture meter used to measure the moisture content of wood, paper, textiles, concrete and other building materials. This multifunction paper moisture meter also measures ambient temperature and ambient relative humidity.

Measuring ranges:

• Wood, paper, textiles: 1 … 75% moisture
• Concrete, building materials: 0.1 … 2.4% moisture
• Ambient temperature: -40 … 70°C / -40 … 158°F
• Ambient relative humidity (RH): 0 … 100 % RH

The FMD 6 is a handy and versatile paper moisture meter for reliable measurement of the moisture content of paper, wood and construction materials. The paper moisture meter has preset characteristic curves for the moisture measurement of specific materials. The moisture meter needs external sensors (sold separately - please see accessory list) to operate.The sensors can be positioned on the surface of a material or inserted into a material, thereby permitting either non-destructive or destructive measurement.

• Measuring range: 5-99% for wood / 0-99% for building materials
• Resolution: 0.1%
• Accuracy: ±0.2%
• Memory stores up to 1,000 measurement values for transfer to PC using  included software

PCE-W3 is a portable handheld digital moisture analyzer used to measure the moisture content of waste paper. This resistance-based moisture analyzer can measure the moisture content of waste paper in compressed stacks and bales. In addition, this moisture analyzer can measure the moisture content of a single piece or sheet of waste paper.

• Moisture content measurement range: 6 … 30 %
• Resolution: 0.1 %
• Accuracy: ±10 % of measurement value

PCE-HT 225E is a roll hardness test hammer, also called a rolled paper rebound hammer or Swiss hammer, used for non-destructive measurements of surface hardness and compression strength. Suitable for use with rolled paper, concrete, rock and building materials, this rebound hammer features a direct digital display, voice functionality, USB port data interface and memory for storing up 200 measurement values.
