Compression Testing Machine Digital Manufacturer,Supplier and Exporter in India
Product Code : EL-CACTE-9450
Jlab Export is a leading Compression Testing Machine Digital Manufacturer,and suppliers in India
Two readouts work side by side on this machine: a 4 digit digital load indicator in kN and a Bourdon tube load gauge with a maximum load pointer. Both show the load at the same time. Pumping is electric with a pace control knob, and a hand operated pump is fitted as well.

Strength Tests and Readout Practice for Students
Running two readouts at once gives students a lesson in reading instruments. During each cube test one student calls out the digital figure while another watches the gauge, and both note the failure load. Comparing the two over a session shows how closely they agree.
The cubes come from the standard practicals: workability on a Slump Test Apparatus, casting in Cube Moulds and crushing at 7 and 28 days. Now and then a ring from the Proving Rings is loaded in place of a cube to check both readouts against a known load.
Frequently Asked Questions
Why does the machine show the load on two readouts?
The digital indicator gives a clear figure in kN, and the Bourdon tube gauge gives a second reading that does not depend on the electronics. If one is ever in doubt, the other still shows the load.
Which reading goes on the test sheet?
Labs normally record the digital figure as the failure load and use the maximum load pointer as a check. If the two disagree by more than a gauge division or so, check both against a proving ring before the next session.
What should be checked before testing starts?
See that the digital display reads zero with no load and set the maximum load pointer back against the gauge needle. Wipe the platens clean and check that the ram is fully down. Then centre the first cube.
Why might the ram not go back down after a test?
The ram returns when the release valve is opened and the oil flows back to the tank. If it stays up, check that the valve is fully open. A ram that still sticks may have a damaged seal or a bent piston, which needs servicing.
