Handy dynamometer for checking the strength of the nets.
The purpose of this instrument is to check the nets once they have been used for a long time in the seawater. Usually in this condition the net deteriorate with a consequent loss of strength.
This dynamometer is made of two parts, the tester for checking the strength connected to a display which shows the measurement.
This instrument is very compact and handy and because of this can be brought to the place where the check has to be done.
The test can be done by acting on the lever until reaching the mesh breakage. Dyna 300D With DYNA 300D you can obtain the following information:
- Tensile strength in Kg.
- Stretching of the mesh in mm.
- Stretching percentage of the mesh.
Few reading are needed to obtain an average value before deciding to discard the net.
This instrument is certified and allow a constant stretching of the net during the tensile strength test.
When performing the test, you can obtain the following graph:
i.e.: stretching test performed on a net with title 210/60
||0 kg||0 %
|| 1 kg
|8 mm.|| 5 kg
|12 mm.|| 12 kg
|16 mm.|| 23 kg
|20 mm.|| 41 kg
|24 mm.|| 58 kg
Refer to the ruler for stretching measurement
Stretching percentage can be calculated with the following formula:
Stretching *100/mesh size
The display is powered by a rechargeable battery with an operating range of 36 hours.
The battery charger is powered with 230 volts.
