This
instrument is equipped with
the latest electronic technology. With its very high
resolution and ultra-stable strain sensor, even very stiff
ceramic watch case can now be easily tested at low pressure. Sigma Electronic has developped
this tester in order to meet
watchmakers' highest requirements. To ensure safety, the
pressuring chamber has been tested with twice the operating
pressure.
The SM-8810/20A can run tests from
-0.7 up to 20 bar, whereas the model SM-8810/30A
reaches up to 30 bar.
Devices
with higher testing pressures on request.
All
models require a pressure booster.
