Features 1、Small and portable, it is convenient to measure the tension of the object when it is taken out. 2、The streamlined body is gray‑black tones, low‑key, steady and stylish. 3、It is made of ABS+ Alloy material, and fine craftsmanship makes the measurement accurate. 4、It has a good hand feeling, is comfortable to hold when measuring, and can be operated with one hand. 5、Wide range of applications, suitable for relay contact pressure, spring tension, electronic switches, etc. Specification Item Type: Tensiometer Material: ABS+Alloy Model Specification: SEG-500-1 Pointer: Single needle Measurement Value: 500g Graduation Value: 10g Scale Style: 100-500-100 Accuracy: ±0.5 Product 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. Tensiometers can be tested either clockwise or counterclockwise, but the stylus arm must always be perpendicular to the direction of the push-pull force; tension scoring is divided into single and double needles. 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
