Item Type: Dial Tension Gauge Material: ABS+Alloy Color: As shown in the picture Model Specification: SEG-300-1 Pointer: Single pointer Measurement Value: 300g Graduation Value: 10g Scale Style: 50-300-50 Accuracy: 0.5 Application: The dial tension gauge is suitable for relay tip pressure, electronic switch, micro switch, valve, spring pull pressure, dial measure equipment principal axis pressure, dial system equipment tip and the gag bitmechanical pressure, tape recorder buffer mechanism pressure, and other precise pressures, pulling force test. How to Use: When test, use the needle move the object from static state to the position needed. The tension gauge test not only along clockwise, but also along the anti-clockwise. The needle must always vertical to the push-pull force direction. Tension gauge set off single needle and dual needle. When the dual needle tension gauge gets the highest value, the needle hold still, convenient user to read.
