A piece of knowledge about these functions will make sure you distinguish between the top products and the merely good ones. Thus, you can make an informed choice.
-
Durability
Your tools must be durable to handle the demands of working in the field. As a compression tester, it will have to deal with all types of tasks, from testing leaks to delivering accurate results. It must be prepared for everything and built with the best materials to ensure it doesn’t break down.
