HARDNESS TESTERS

Note: Pendulum supplied separately - see below

This Pendulum Hardness Tester has a lot of unique features that ease defining hardness by the König and/or Persoz method as described in ISO 1522. Both methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.
The instrument has an easy menu-driven interface with jog dial. The automated electronic counting mechanism is not affected by reflections from the surrounding area. The water-level is located on the test specimen, rather than on the instrument’s base. Once the instrument is leveled further calibration is not required. The gas-spring supported transparent draft cover allows easy access to all parts of the instrument.
The Pendulum Hardness Tester is a modular system. The instrument itself can be used for both the König and- Persoz method. Both pendulums should be ordered separately. After placing the correct pendulum, switching between the two measuring methods only takes a push of a button. The Pendulum is positioned fully automatically by means of a stepper motor. Also the release of the Pendulum is automated through electro-magnetic system. The end of a test is indicated by a visual and acoustic signal.

These test blocks are used to check and help maintain Durometer hardness readings with test blocks ranging from 30 Durometer to 90 Durometer type A.

The Buchholz Test is a method for carrying out an indentation test on coatings in compliance with ISO 2815-2003. The kit consists of a calibrated slip-on weight with a sharp-edged metal wheel, an illuminated microscope, a level gauge, a digital dual timer, and two markers with template. The sharp-edged wheel with weight is positioned on the test specimen for a set period of time. The length of the indentation mark in the coating is an indication of the hardness of the surface.

The Barcol hardness tester is a portable instrument for testing the hardness of materials. When pressure is applied to the device, a point penetrates the material and the degree of hardness is displayed on a dial, which is graduated from 0-100 Barcol Hardness which can be converted into Brinell, Vickers, & Rockwell Hardness. This model suitable is for soft metals such as aluminum and its alloys, brass, copper, and some harder plastics, in accordance to ASTM D2583.

The Shore Hardness Gauge is used for measuring the hardness of materials such as polyester, ABS, nylon, polyurethane, kevlar, acryl, wood, polystyrene. The unit is supplied with a drag indicator which is used to register the highest measured result.
Supplied as standard with: case.

This is a very simple and effective way of testing the resistance of a coating to scratching. The pencil is mounted in a carrier of pre-determined weight (750g) to ensure a standard pressure is applied to the pencil as it travels across the coating. A visual assessment is then carried out to determine the damage and subsequently hardness of the coating.
Supplied as standard: a selection of pencils of differing hardness, pencil holder, Calibration certificate.

This is a very simple and effective way of testing the resistance of a coating to scratching. The pencil is mounted in a dual-weight carrier of (either 750g or 1000g according to test standard) to ensure a standard pressure is applied to the pencil as it travels across the coating. A visual assessment is then carried out to determine the damage and subsequently hardness of the coating. Supplied as standard: a selection of pencils of differing hardness, pencil holder, Calibration certificate.
