| Elcometer 501 Pencil Hardness Tester |
 Product Infomation
|
Using the same technique of evaluation with pencils as the Elcometer 3080, this instrument enables the pencil lead to be maintained at a constant force of 7.5N, and at the appropriate angle - which increases the reproducibility of the test.
The Elcometer 501 is supplied in a plastic carrying case and comes complete with a set of pencils in each of the 14 hardnesses from 6B to 6H, a pencil sharpener and a sandpaper block. |

| Elcometer 3086 Motorised Pencil Hardness Tester |
| Product Infomation
|
Similar to the Elcometer 501 and using the same pencil technique, this motorised device in anodised aluminium can travel forwards (chip method) or backwards (indentation method) at a uniform speed - further increasing the reproducibility of the test.
The load on the lead is adjustable from 0 to 10N and each instrument is supplied with a lead holder and a set of 6 leads in each of the 14 hardnesses. |

| Elcometer 3092 Sclerometer Hardness Tester |
| Product Infomation
|
The body of the instrument contains a round tip, compressed by one of the three springs corresponding to the three printed scales: 0-300, 0-1000, 0-2000g, and a cursor fitted with a screw lock.
By making short, straight movements while gradually increasing the load, the user can observe the force at which the tip leaves a mark or destroys the coating.
Each Elcometer 3092 is supplied in a case with 0.75mm diameter tungsten carbide tip and 3 springs. |

| Elcometer 3030
& 3040 Persoz & König Pendulum Hardness Testers |
| Product Infomation
|
These instruments work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness. The amplitude of the oscillation reduces faster when the sample is soft.
The Persoz and K?nig methods differ by the dimension, period and amplitude of the oscillation.
The Persoz test measures the time taken for the amplitude of oscillation to decrease from 12° to 4°.
The K?nig from 6° to 3°. |
|
|
|
|
Hence the König will take approximately half the time to test the same sample as the Persoz.Available in 3 models: Persoz, K?nig, and Persoz and K?nig combined.
Standard equipment includes:
Hood to protect against draughts, fitted with a front door and a side opening to simplify sample handling.
Practical system to facilitate sample tightening and loading of pendulum, with automatic release.
Maximum sample dimensions: 200 x 110 x 15mm (7.85 x 4.33 x 0.6").
Accurate, automatic counting by photoelectric cell.
Digital display.
