Item Type: Tension Gauge Material: ABS+Alloy Model Specification: SEN-3-1 Pointer: Single Pointer Measurement Value: 3N Graduation Value: 0.1N Scale Style: 0.5-3-0.5 Accuracy: 0.5 Weight: Approx. 125g / 4.4oz Product Use: Tensiometer (N) 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 use the stylus to move the object to be tested 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; tension scoring is divided into single and double pointers. The single-pointer tensiometer measures and reads immediately. After the double-pointer tensiometer measures the highest value, follow-up pointer stops moving, which is convenient for the tester to read the test value.
