Ref: Testex Tape
Testex Press O Film offers a unique replica technique and with a simple snap gauge will allow you to take accurate, low-cost blast-surface profile measurements. Testex makes surface replicas easy to obtain and produces average maximum peak-to-valley readings that ensure optimum blasting effectiveness. Replicas can be retained for future needs.The accuracy of Testex measurements is due to an innovative two-level film that can produce virtually exact replicas of the abrasive blasted surfaces. The film is available in three different thickness grades to cover the most common range of blasted profiles.Measurements can be taken in internal pipe diameters and grooves, which are locations that are not accessible using conventional stylus devices.Easy to use, remove the protective paper from the tape and place firmly on the blasted surface. Apply moderate pressure with the Burnishing Tool over the circular cut-out in the tape. Remove the tape. The replica is now ready for measurement using the Snap Gauge.
The Testex Gauge is used to measure the Testex Tape and determine the average maximum peak-to-valley height of the blasted profile.Measurements are made by firstly zeroing the gauge on 50µm (2mils). This is to allow for the film backing. Place the replicated area between the anvils and gently lower the moveable anvil onto the film. The reading can now be taken, giving you the average peak-to-valley height of the blasted profile.Supplied with as in a Foam-Filled Carrying Case with 1 roll of Coarse Testex, 1 roll of X Coarse Testex and a Burnishing Tool.
Ref: Roughness Comparator
The ISO Surface Roughness Comparator is a precision Nickel Comparator Plate that conforms to International Standard ISO 8503 and ASTM D4417 for grit and shot-blast surface roughness comparison measurement.When steel has been blast-cleaned, the surface consists of random irregularities with peaks and valleys that are not easily characterised. Experts have recommended that the profile should be identified as dimpled (shot-blast) or angular (grit-blast), and that they should be graded as Fine, Medium or Coarse with each grade being defined by limits specified in ISO 8503. These characteristics are considered to give sufficient distinguishing features for most painting requirements.
