Feature

●This is a hardness gauge that allows you to easily inspect the safety of your toy, furniture, appliances, and interior edges. Conforms to UL1439 technical standards for reliability.
●First, attach the tester head to the axis of the body, then slide the 1.5lb force along the edge of the measurement. Then slide back to the origin with the same force.
●After the slide is complete, check the tester head and if the outer two layers (simulated skin) break, the measured edge is sharp. 21 tester heads are included so you dont need to buy them separately.
●Mechanical construction that does not require power and is less likely to failure and is less cost-effective than large electronic sharp edge testers. Lightweight and simple to operate, making it easy for beginners to use.
