1 DESCRIPTION AND OPERATION OF THE DEVICE AND ITS COMPONENTS
1.1 Application
The device is intended for measuring the thickness of coatings, parameters of the environment, and
measurement of the depth of cavities and surface roughness.
1.2 Specification
Coating Thickness Gauge NOVOTEST TP-2020 is a portable device with a shockproof body made
of ABS plastic enclosed in a silicon bumper, and a circuit board with electronic components and
batteries. The thickness gauge meets ISO 2808.
The device specifications are shown in the tab. 1.1.

Parameters of test objects:
−
surface roughness is not more than Rz 1 (without averaging);
−
the minimum curvature radius is 0.3 - 50 mm depending on the used probe.
Body protection
The protection of the device from penetration of solid objects and water meets IP 54 under GOST
14254.
Mean time between failures
The average mean time between failures of the device without reliability index of probes is not less
than 6000 h.
Note – The average mean time between failures of probes is standardized with consideration of
roughness of the surface of the test object R
z
= 1.0 µm.
Service life
The complete service life of the device is at least 10 years.
The average service life of probes is at least 2 years.
The criterion of the limiting state is the economic inexpediency of recovery of the device
components by repair.
