Sponge Hardness Tester - LX-F

First, in order to measure the hardness of foam, we have lanched the tailor-Made LX-F type

sponge durometer to facilitate our customers. It is suitable for the inspection of

soft foam,polyurethane foam and rubber products. And it will be different with

the other hardness tester In some aspects. The presser foot directly

contact to the sample,and see it sown weight as force measurement load.

Main parameters:

Scope of pressure needle route:0~2.5millimeters.

The scale value:0-100 degrees.

The force of pressure needle end:550mN~4300mN(56~438.5g).

How to use:

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 the

accuracy of measurement, you should putthe sample on a flat plate glass or plate.

Each measuring point should be measured only on forth,

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 notshow “0’ and “100”

whenchecking,adjustitto“0’and“100

2,The sample and adjustments

The specimen thicknesss houldbe 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 thicknesss tills hould conform to the sample thickness.

The sample size should satisfy thel ength and the width are larger than100mm,

The distance between the measuring point and sample edge is not less than 40mm,

All measuring point are less than between 25mm,each sample pointsi s 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.

SampletestconditionsaccordingtoGB/T2941-91provisions.
