Measuring Higher Temperatures
The polyurethane membranes fitted to the single element probes
are suitable for measuring surface temperatures up to 70°C
(160°F). For measuring higher temperatures Teflon membranes
are available and suitable for surface temperatures up to 150°C
(300°F) with intermittent contact. Contact Cygnus instruments to
order Teflon membranes.
When measuring high temperatures limit the time the probe is in
contact with the hot surface to less than 4 seconds and ensure the
probe has sufficient time between measurements to cool down.

Cast irons, plastics
General purpose
Most metals
Thin metals
Typical Uses
General purpose probe suitable
for most applications that can
use Multiple Echo
measurement.
Coated metals
As S2C but has longer focal
point (33 mm) and narrower
beam so may perform better
on thicker materials
