Sigma SM8850-20 Water Resistance Tester.

The SM-8850-20 has been especially developed for the watch manufacturing and the after-sale service. The reduced volume of the chamber allows the instrument to perform a quick water-resistance test with high pressure for large watches. The SM8850-20 test accurately to 20 bar / 200mts.

The sensor head is placed high enough to allow watches with rigid straps / bracelets to be tested easily. The automatic process lifts the watch to the correct testing position. An LCD panel displays test settings, parameters and results.

The SM-8850 range is available in three different air pressure configurations:

- SM-8850-20: from -0.7 to 20 bar
- SM 8820-30: from -0.7 to 30 bar
- SM 8820-50: from -0.7 to 50 bar

In order to test watches with the highest pressure provided by the instrument, it is necessary to connect the SM-8850 to a compressor. We are pleased to advise you on the best combination of booster and compressor.
