The Graftel
Model 1239.SIT extensometers are precision instruments used to measure
the growth of containment during an SIT. They are digital smart sensors
like the Graftel Model 9202s and 9203s. The Model 1239.SIT extensometers
are fully compatible with the Graftel ILRT instrumentation
system. The
need for additional SIT temperature sensors is eliminated.
Graftel can supply the sensors,
the software for reading them, calibration and any required training.
