PosiTest AT-A PosiTest - Automatic Adhesion Tester


Made in the USAThe Positest AT-A Automatic Adhesion Tester measures the force required to pull a specified test area of coating away from a substrate using hydraulic pressure. An electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. The pump greatly reduces user effort and the risk of influencing the pulling process.

The AT-A's built-in rechargeable battery performs over 200 tests per charge. The supplied AC adapter / charger allows you to continue testing with AC power while the battery recharges.

The AT-A is features an environmentally sealed enclosure. It is weatherproof, dustproof and shockproof. Meets and even or exceeds IP65 rating.

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

  • Impact and scratch resistant color touch screen with keypad for operation with or without gloves
  • Record the results as pass/fail and the nature of fracture - cohesive, adhesive and glue failures
  • Conforms to international standards including ASTM D4541 D7234, ISO 4624 16276-1, AS/NZS 1580.408.5 and others
  • User selectable measurement units: psi (pounds per square inch), MPa (Megapascal), Nmm2 (Newtons per millimeter square) or Newton (force)
  • Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cell
  • User adjustable pull rate, pull limit and hold time
  • Internal memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for 100,000 pulls in up to 1,000 batches

ATA Self-Alignment Feature

PosiTest ATA self alignment feature Unequal pulling force during testing caused by uneven adhesive bond lines and coating surfaces can result in random, unexplainable readings. To obtain more repeatable and meaningful adhesion measurements, it is imperative that the pulling force applied to the test dolly is uniformly distributed over the surface being tested.

Both the PosiTest AT-M manual and PosiTest AT-A automatic models compensate for misalignment. The self-aligning, quick-coupling actuator and spherical articulating dolly head enable uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.
