Inbuilt Printer Dry Film Paint Thickness Tester Elcometer Coating
Thickness Gauge TG110
Applications:
The TG110 measures the thickness of non-magnetic materials (e.g.
paint, plastic, porcelain enamel, copper, zinc, aluminium, chrome
etc.) on magnetic materials (e.g. iron, nickle etc.) . often used
to measure the thickness of galvanizing layer, lacquer layer,
porcelain enamel layer, phosphide layer, copper tile, aluminium
tile, some alloy tile, paper etc.
Features:
- With different external probes, the gauge can be applied to
measuring thickness of non-magnetic coating on magnetic metal
substrate, as well as non-conductive coating on non-magnetic metal
substrate.
- Two measuring modes: single or continuous, changeable.
- Two work modes: direct or group, changeable.
- High precision mode: multiple measurements and automatically data
filtering method to reduce disturbance of measure results
- Temperature compensation: compensate the measurement distortion
caused by the drifting of temperature.
- Give five statistical values: average, maximum, minimum, measure
number, and standard deviation.
- Two calibration methods can be applied to the gauge; And the system
error of the probe can be corrected with the basic probe
calibration method.
- Data storage: up to 500 measurements storage.
- Set boundary: alarm while measurements out of boundary.
- Battery information indicates the rest capacity of the battery.
- Beep prompting.
- Five statistical data:MEAN,MAX,MIN,NO.,S.DEV
- Auto power off function to conserve battery life.
Measuring Principles
The gauge adopts two thickness-measuring methods: magnetic
induction method and eddy current method.
Magnetic Induction method: The probe and the magnetic metal
substrate will form a closed magnetic circuit when probe contacting
with the coating; the magnetic resistance of closed magnetic
circuit varies due to the existing of non-magnetic coating. The
thickness of the coating can be measured through the variation of
magnetic resistance.
Eddy current method: The high frequency alternating current
generates an electromagnetic field in the probe coil; eddy current
will be formed on metal substrate when the probe contacting with
the coating, and the eddy current has an effect of feedback on the
coil in probe. The thickness of the coating can be calculated
through measuring the effect of feedback.
The range of applications is indicated by the probes available.
-F probes work on the magnetic induction principle and should be
used for non-magnetic coatings such as aluminum, chrome, copper,
zinc, paint and varnish, enamel, rubber etc., on an iron or steel
substrate; they are also suitable for alloyed and hardened magnetic
steel.
- N probes work on the eddy-current principle and should be used
for insulating coatings on all non-ferrous metals and on austenitic
stainless steels, e.g. paint, anodizing coatings, ceramics, etc.
applied on aluminum, copper, zinc die-casting, brass, etc.
