The TQC Film thickness gauge is a high precision film and foil thickness gauge, especially developed for measuring so-called “replica tapes” as Testex®, used mainly to measure the surface profile.
The large clear display makes it easy to read the measurement under all conditions. Values can be displayed in either microns or inches.
To minimise the influence of body/hand temperature the gauge is mounted detached from the holder.
The TQC film thickness gauge operates completely according to “ISO 8503-5 Preparation of steel substrates before application of paints and related products – Surface roughness characteristics of blast-cleaned steel substrates – part 5: Replica tape method for the determination of the surface profile.”
As described in this standard the closing force is 1,5 N. The gauge has to have an accuracy of 5 micron and a resolution of 1 micron.
The TQC Film thickness gauge is supplied in a hardcase.
With the new Surface Profile probe you can use the body of the PosiTector 6000 as a SPG Surface Profile Gauge.
The SPG Surface Profile probe measures and records peak to valley surface profile heights.
Conforms to ASTM D4417-B, AS 3894.5-C (with optional 30° tip angle), U.S. Navy NSI 009-32, SANS 5772 and others.
All PosiTector 6000 probes can be used with the PosiTector SmartLink; a small piece of hardware that physically connects to new and existing PosiTector probes and wirelessly connects to a free PosiTector app, turning it into a virtual PosiTector gage. You will find the Smart Link device under ‘accessories’.
The TQC Surface Profile & Coating Thickness gauge is a combination gauge. that can be equipped with two different tips, one for surface roughness and another for coating thickness.
Supplied with a sharp tungsten carbide replaceable tip for surface profile measurement, a hardened round tip for coating thickness measurement, a glass plate for zero calibration and a leather carry pouch that fits all items.
Replica tape for measuring blasted surface profiles. By placing the Tqc replica tape on the surface and rubbing over it, the Rt (total roughness) or peak-to-valley height of the profile can be taken and then measured with a film thickness meter.
1. TQC Replica tape consists of a layer of compressible foam affixed to an incompressible polyester substrate.
2.When pressed against a roughened/gritblasted (steel) surface, the foam collapses acquiring an impression of the surface.
3.Placing the compressed tape between the anvils of the SP1570 micrometric thickness gage, and subtracting the contribution of the incompressible substrate (50 micrometers or 0.002 inches), gives a measure of the surface profile.
One box of Testex contains tape for 50 measurements.
