LX-F Shore Foam Portable Hardness Tester, Sponge Durometer
LX-F Shore Foam hardness tester / Durometer
LX-F is suitable for the determination of soft foam, polyurethane foam rubber products’ hardness. And itwill be different with the other hardness tester In the aspects of using. When using the presser foot directly contact to the sample, and see it sown weight as force measuremen tload.
This hardness gauge conforms to the regulations of GB/T531-99, GB2411-80, hg/t2489-93, JJG304-2003.
Specifications:
1. Scope of pressure needle route: 0~2.5millimeters.
2. The scale value: 0-100 degrees.
3. The force of pressure needle end: 550mN~4300mN (56~438.5g).
Using Methods:
Held the middle of the instrument located the hardness tester gently on the plane Specimens which is bigger than presser foot (orspecimen). Reading out the value in 1 second when durometers’ presser foot contact with the samples moothly. And the tick of pointers is the hardness value of sample (specimen). In order to improve theaccuracy of measurement, you should putthe sample on a flat plate glass or plate. Each measuring point should be measured only on
Calibration Methods:
When the durometer presser foot is in the free state, it points \"0\".The pressure needle end and the pressure foot flat is in close contact with the glass surface, the indication should be \"100\" If the Durometers’ pointer can not show “0’ and “100” when checking, adjust it to“0’and“100
