Since its first issue, the Water-Resistance Tester SM-8850 series has undergone continuous improvements and enhancements. With its state-of-the-art advanced technology, the latest version includes important new features and functionality.
Similar in user-friendliness as its worldwide recognized and adopted predecessor, it comes with a significant increase in performance among many other advantages. The SM-8850/10 instrument allows to test watches at pressures ranging from -0.75 to 10 bar, respectively to 20 bar for the SM-8850/20, 30 bar for the SM-8850/30 and 50 bar for the SM-8850/50.
This series of test instruments is optimized for very high pressure testing. The new pressuring chamber is designed to withstand pressures in excess of 100 bar and to cater for very big sized watch-cases and even diving watches of a thickness of up to 35 mm, a width of 65 to 79 mm and a length of 78 to 104 mm. This extension in test object size was created without increasing the internal chamber volume: with less than 0.5 litre of volume, the pressuring chamber features a reduction of more than 15% compared to its predecessor, and more than 60% compared to other competitors, allowing shorter test cycles and lesser air consumption, especially for high pressure tests.
A new front locking system with safeguard, along with a redesigned compact side lock for the high pressure versions ensures a safer operation of the device.
