Now available from Testequip , the LEPTO-Pen is a coating thickness gauge that works on untempered commercial quality steel substrate according to the known magnetic attraction principle (EN ISO 2178).
Composed of a precision magnet and a mechanical spring balance, the scale of which is calibrated and labelled in µm coating thickness, this coating thickness gauge is a simple and economical alternative where the high accuracy of the electronic coating thickness gauge is not necessary.
These coating thickness gauges are simple to handle and operate and have a minimum working life of 500,000 measurement cycles.
The LEPTO-Pen coating thickness gauge is available in two models:
- Model 2091.001: scale 0 to 800 µm / 0 to 30 mils. Measuring range: 10 to 500 µm / 0.25 to 20 mils. Measurement uncertainty within the measuring range: +/- 10% +/- 3 µm.
- Model 2091.002: scale 10 to 1000 µm / 0.5 to 40 mils. Measuring range: 20 to 750 µm / 0.75 to 30 mils. Measurement uncertainty within the measuring range : +/- 10% +/- 3 µm.
These stated values are valid for planar steel from St 52-3 (1.0570) with a minimum thickness of 1mm. Similar values are applicable for most untempered steel grades.
These coating thickness gauges have a working temperature range of 0°C to 40°C and a storage temperature of -20°C to 50°C.
The Permissible relative humidity is less than 80%.
