12 TECHNICAL DATA

12.1 MEASUREMENT SPEED
>60 readings per minute.
When measuring high temperature materials
measurement speed must be reduced to prevent
overheating
of
the
measurement speed of the High Temperature
PINIP™ probe at 250°C (480°F) is 4 readings per
minute.
12.2 MINIMUM SUBSTRATE THICKNESS
Ferrous: 300 µm (12 mils)
Non-ferrous: 100 µm (4 mils)
Measurements can be taken on thinner substrates
if 2-point calibration is carried out either side of the
required substrate thickness, however gauges will
have reduced range when adjusted for thin
substrates.
