Bally Waterproofness Tester
Bally Waterproofness Tester is to test materials like coated leather, leather dynamic water penetration resistance ability. The material would be partially put in water and the bally water penetration tester would flex the sample in the water under certain speed to simulate material water resistance in daily work.
Principle：
A rectangular test specimen is bent partly round, and secured between, two cylindrical clamps so as to form a trough. The trough is then immersed in water and the clamps oscillate at a constant speed so that the specimen is repeatedly flexed. The time taken for water penetration through the test specimen to occur is recorded. The mass of water absorbed by, and transmitted through, the test specimen can also be measured.
Parameter:
Test quantity：4 sets
Test stroke：2mm, 3mm, 4mm, 6mm (adjustable)
Speed：50 CPM
Counter：LCD, 0 ~ 999,999
