Feature:1. Mechanical dial with accurate data, mechanical dial is more accurate than the digital display instrument.2. Widely used for relay tip pressure, electronic switch, micro switch, valve, spring pull pressure etc.3. The use of highquality alloys and fine craftsmanship forging make the measurement more accurate.4. Small and portable style, streamlined body, comfortable to hold and easy to measure.5. With stable performance, the transparent cover makes it clearer to see the reading.Specification:Item Type: Dial Tension GaugeMaterial: ABS+AlloyColor: As shown in the pictureModel Specification: SEN-1-2Pointer: Double pointerMeasurement Value: 1NGraduation Value: 0.02NScale Style: 0.2-1-0.2Application: 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..Package List:1 x Dial Tension GaugeNote: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.
