1It is pocket size, light in weight ,streamlined fuselage, easy to carry out for fieldwork if needed. 2The dial tension gauge is suitable for relay tip pressure, electronic switch, micro switch, valve, spring pull pressure. 3The use of highquality alloys and fine craftsmanship forging make the measurement more accurate. 4The newly designed tensiometer is operated with onehanded grip, and having a good feel can make the measurement work easier. 5Exquisite outline, precise pointer, the transparent cover makes it clearer to see the reading. Item Type: Dial Tension GaugeMaterial: ABS+AlloyColor: As shown in the pictureModel Specification: SEG-300-1Pointer: Single pointerMeasurement Value: 300gGraduation Value: 10gScale Style: 50-300-50Accuracy: 0.5Application: 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. 1 x Dial Tension Gauge 1. Do not drop the product randomly.2. Do not bend the measuring alloy probe.3. When the product cannot be calibrated, you can open the back cover for calibration. It is not recommended to open the back cover for calibration frequently.
