TLS-I Series Digital Display Spring Tension and Compression Testing machine
The load measurement of this tester is digitally displayed, which avoids the reading error of human eyes. The displacement measurement is indicated by staff gauge and vernier, which gets rid of the displacement caused by the deformation of the load cell, and therefore the measured displacement is more accurate. The machine is easy to operate, with high efficiency, high precision and stable performance, etc.
Load display mode: Digital display, with indication function at upper & lower Limit.
Displacement display mode: Staff gauge & vernier indication, with micro-adjusting unction.
Loading mode: Manual loading, quick and convenient, displacement control through positioning devices. (Above 5000N, automatically loading).
Overload protection: Digital cell glittering in case of over test load. (Autostop in case of automatically overload).



TLS-SI Series Dual Digital Display SpringTension & Compression Testing Machine
TLS-S I series of spring tension & compression testing machine adopts integrated circuit and micro-computer to test the 2 parameters of displacement and load and to digitally display their values, as well as printing out the testing results.
Hand loaded, the machine can pre-set the upper & lower limit load of 4 test points and auto judge the qualification of the 4 test points. It can also auto-revise displacement of the load cell.
Generally, the machine has functions of peak value holding, overload protection, zero clearing at any test point, stiffness calculation, data retrieval, etc. It is suitable for testing of various precision extension and compression springs and intensity measuring of brittle materials.


TLS-S II Series Full-automatic Dual Digital Display Spring Tension & Compression Testing Machine
TLS-S II Series automatic dual digital display tension & compression testing machine is a new spring testing instrument, which uses several advanced technologies so as to further improve the test accuracy and ensure the testing efficiency. The test load is divided into 3 grades so that the measuring range is expanded. The machine can test 9 testing points at deferent speeds and return to the initial position automatically. 6 types of files can be stored for future usage. It can also auto-revise the displacement of the load cell. What's more, the machine also has functions of peak value holding, overload protection, zero clearing at any test point, stiffness calculation, data retrieval, etc.
This series spring tester also can be controlled by the computer according to add a computer system as an optional part.
