LX-F Sponge Foam Hardness Tester Durometer
1.Character:
LX-F type sponge hardness meter is our customers in order to facilitate the measurement of foam hardness and the special custom, it is suitable for determination of soft foam, polyurethane foam rubber products hardness, the hardness and other hardness in determination using different, when in use, the presser foot directly onto contact, and the using its own weight as a load load.
2.Parameters:
| Pressure stroke of the needle Range | 0-2.5 mm |
| Dial value | 0~100 degrees |
| Pressure needle end force | 550mN~4300mN(56~438.5g) |
3.method of using:
Handheld the middle of the instrument, located the hardness tester gently on the plane specimens which is bigger than presser foot (or specimen). Reading out the value in1 seconds when durometers’ presser foot contact with the sample smoothly. And the tick of pointers is the hardness value of sample (specimen). In order to improving the accuracy of measurement, you should put the sample on a flat plate glass or plate. Each measuring point should be measured only one time, the measuring point at a distance of more than 25mm of different parts from the same sample should be more than 5 points. To take the average of measurement results, namely it’s the hardness value of the materials
4.Attention:
1 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
2, The sample and adjustments
- The specimen thickness should be in 25mm to 30mm, when insufficient thickness of 25mm, you can stack 2 pieces. but you need to ensure the flat surface smooth, the whole thickness still should conform to the sample thickness.
- The sample size should satisfy the length and the width are larger than 100mm, the distance between the measuring point and sample edge is not less than 40mm, all measuring point are less than between 25mm, each sample points is not less than five points.
- Take out the skin of both sides of the specimen, the thickness should be uniform, smooth surface, micro-hole distribution uniformity, no mechanical damage and impurities.
- Sample test conditions according to GB/T2941-91 provisions.
3, After using the hardness tester, put it in instrument box, put in dry place to prevent moisture.
