PosiPen

The Defelsko PosiPen is a portable, precise, and durable magnetic thickness gauge, ideal for measuring coatings on steel in hard-to-reach areas, complying with ASTM and ISO standards.

The Defelsko PosiPen is a compact and accurate magnetic thickness gauge, perfect for quick inspections on metallic surfaces, even in small or difficult-to-access spaces. With dual scale (mils and microns) and a PTB-traceable calibration certificate, it provides reliable performance in industrial and laboratory environments.

Main Features

• Measurement range: 0.25 to 20 mils / 5 to 500 μm.
• Accuracy: ±10% ± 0.1 mils / ±2.5 μm.
• Operating temperature: -150 to 450 °F / -100 to 230 °C.
• Triple display: compensates for gravity in different measurement positions.
• Durable and resistant: ruby tip, water-, oil-, impact-, and dust-resistant.
• Lightweight and portable: pen-sized, ideal for quick inspections.

How does the PosiPen Works?

1. Place the tip of the PosiPen on the coated surface and let the magnet make contact.
2. Remove the gauge straight from the object while observing the scale.
3. Record the reading when the magnet releases.
