Manual Adhesion Tester – Dolly size & standoff: 20 mm, Typical applications: Coating on Metal
- PosiTest® AT-M 20 mm Kit Adhesion Tester with Pelican Case
- Internal memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for up to 200 pulls
The PosiTest AT Pull-Off Adhesion Tester measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure. The pressure is displayed on a digital LCD and represents the coating’s strength of adhesion to the substrate.
Simple
- Portable — requires no external power source – ideal for field or lab use
- Pull Rate Indicator allows operator to easily monitor and adjust the rate of pull in accordance with international test methods
- Easily select dolly sizes, change measurement units or store readings with the touch of a button
- Conversion charts not required – tester automatically calculates pressure based on dolly or plate size
- Inexpensive, single-use dollies and plates eliminate cleaning for re-use and can be kept as a permanent record
- Each kit comes with everything needed for testing
Durable
- Environmentally sealed enclosure – weatherproof, dustproof and shockproof — meets or exceeds IP65
- Can be used in any position
- Hard-shell carrying case included, with optional upgrade to a heavy-duty Pelican® case
- Two year warranty
Accurate
- Calibrated and certified to +1% accuracy using a NIST traceable load cell. Certificate of Calibration showing traceability to NIST included.
- Self-aligning dolly enables accurate measurements on smooth or uneven surfaces
