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
