Feature: 1. Small and portable dynamometer, easy to take out to measure the force of objects. 2. The streamlined body is gray‑black tones, low‑key, steady and stylish. 3. The use of high‑quality alloys and fine craftsmanship forging make the measurement more accurate. 4. The tensiometer that can be held with one hand makes the measurement easier. 5. It is suitable for measuring the pressure of relay nodes, electronic switches and other local forces. Specification: Item Type: Tensiometer Material: ABS+AlloyModel Specification: SEG-50-1 Pointer: Single Needle Measurement Value: 50g Graduation Value: 1g Scale Style: 10-50-10 Accuracy: ±0.5Product Use: Tensiometer (in grams) is suitable for mechanical pressure such as relay contact pressure, electronic switch, micro switch, valve, spring tension, dial measuring instrument spindle pressure, automatic telephone equipment contact and armature pressure, tape recorder buffer Device pressure and other contact point pressure, and other precise pressure and tensile tests. How to use: When testing, just pull the object to be tested with the stylus to move it from the static state to the required position. The tensiometer can be tested either clockwise or counterclockwise, but the stylus arm must always be perpendicular to the direction of the push-pull force. Tensiometer divide into single needle and double needle. The single-needle tensiometer measures and reads immediately. After the double-needle tensiometer measures the highest value, the slave needle stops moving, which is convenient for the tester to read the test value.. Package List: 1 x Tensiometer Note: 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.
