ERICHSEN SmartPen : digital display with 0.05 N resolution !
Hardness Test Pencil with digital Test Force Setting
The ERICHSEN SmartPen is used to determine the scratch resistance of surfaces; depending on the used module, it can be used to determine the resistance to scratching, the tendency towards metal marking and the durability of printed markings.
For the hardness measurement of surfaces, there are our since many years well-proven hardness test pencils, models 318 and 318 S as well as models 435 and 435 S, already well established across the branches.
With these test devices, the degrees of hardness of paint films, plastic coatings, etc. can be determined, named, documented and communicated in numerical values.
No matter whether on a flat or curved surface, small or large, the instrument is always ready for use and, because of it’s small size, easy transportable.
With the ERICHSEN SmartPen, a modular hardness test pencil with digital test force setting and display (resolution 0.05 N) is now available.
The SmartPen is supplied in a plastic case with three springs and a USB-C charging cable.
If there is no corresponding additional selection in the P.O., the SmartPen is supplied without test head.
Depending on the requirements, the user can choose all of the test heads with the corresponding test tools from our hardness test pencils or test rods from the model series 318/435.
Also the test heads of existing ERICHSEN test rods can still be used.

A Note of Concept
The scratch resistance is perceived by a large number of users and for many years – incidentally not physically correct and therefore misunderstood - as related to the term hardness”, means in a proportionally assignable manner.
Not least due to the often used term “scratch hardness”, the “hardness” has mistakenly become part of the historically grown and living vocabulary of testing the resistance against moving mechanical treatment/influence which is the subject here.
This explains the term “hardness test pencil”, which has already been established for decades.
Purpose and Application
For the hardness measurement of surfaces, there are our since many years well-proven hardness test pencils, models 318 and 318 S as well as models 435 and 435 S, already well established across the branches.
With these test devices, the degrees of hardness of paint films, plastic coatings, etc. can be determined, named, documented and communicated in numerical values.
No matter whether on a flat or curved surface, small or large, the instrument is always ready for use and, because of it’s small size, easy transportable.
With the ERICHSEN SmartPen, a modular hardness test pencil with digital test force setting and display (resolution 0.05 N) is now available.
The SmartPen is supplied in a plastic case with three springs and a USB-C charging cable.
If there is no corresponding additional selection in the P. O., the SmartPen is supplied without test head.
Depending on the requirements, the user can choose all of the test heads with the corresponding test tools from our hardness test pencils or test rods from the model series 318/435.
Also the test heads of existing ERICHSEN test rods can still be used.
Easy to use :
The desired spring force is set by turning the upper part of the pencil and can be read on the digital display (adjustable in 0.05 N steps).
Screw the test head with the selected test tip and pring.
Switch the ERICHSEN SmartPen ON by pressing the button.
With the locking device, the force setting of pencil is released or determined.
Lock the force setting.
Place the SmartPen vertically on the surface to be tested, press firmly enough until the test tip or tool is maximally retracted into the head and draw a line approx. 5 to 10 mm long with approx. 10 mm/s.
The test tool should produce a scratch which is just hardly visible with the naked eye. If the spring pressure is too high, the scratch is clearly visible; if too low, no scratch
trace appears.
The force setting process is the same for all equipment variants:
- Loosen force adjustment.
- Place the SmartPen vertically on a flat, rigid surface and apply appropriate pressure to ensure that the used test tip or tool is maximally retracted into the head and remains retracted during the entire force setting process.
Using test heads 435/435 S:
Screw the test head „435“ with a test disc and the selected spring (after tighten the screw it must not be possible to turn the test disc).Place the SmartPen vertically on the test surface.
The guide wheels must touch the surface.
