PosiTest AT-A PosiTest - Automatic Adhesion Tester

The new AT-A Automatic Adhesion Tester measures adhesion of coatings to metal, wood, concrete and other rigid substrates and now features a new electronically controlled hydraulic pump.

Simple

• Portable, hand-operated instrument requires no external power source – ideal for lab and field use.
• Large, easy-to-read LCD
• 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 size
• Inexpensive, single-use dollies eliminate cleaning re-use and can be kept as a permanent record
• Each kit comes with everything needed for testing

Durable

• Weatherproof, dustproof and shockproof
• Quality hydraulic pump can be used in any position
• Rugged carrying case
• One year warranty

Accurate

• Every AT-100 Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy using an NIST traceable load cell
• Self-aligning dolly enables accurate measurements on smooth or uneven surfaces
• Hi-grade, industrial pressure sensor ensures continued accuracy
• Conforms with ASTM D4541/D7234, ISO 4624, SSPC-CS 23.00/AWS C2.23/NACE No. 12, and others

Versatile

• Internal Memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for up to 200 pulls
• Optional software available for downloading to a computer
• LCD displays pressure value in psi or MPa
• 10, 14, 20 or 50 mm dollies maximize capability and accuracy across a wide range of bond strengths
