+/–0.1 % IACS below 10 % IACS] at 20 °C
[+/–0.8 % IACS at 100 % IACS reducing to +/–0.2 % IACS at 10 % IACS
+/–0.2 % IACS below 10 % IACS] over range 0 °C to 40 °C with probe in contact
with metal
12.7 mm diameter, for 60 kHz, and 500 kHz. 8 mm probe operates at 500 kHz only.
Probes are interchangeable with simple customer re-setting procedure.
The probe fi eld is sharply defi ned and enables accurate measurements to be made
even with the probe in line with the extreme edge of the metal.
Special probe guides are available for measuring curved surfaces. The data for
three probes of each size can be stored in the probe data fi eld allowing for alterna-
tive probe usage.
