The material decides the moisture meter, because each meter is built and calibrated for a specific material. This guide covers grain, hay, wood, building materials, bulk biomass and laboratory samples, and explains when a quick field meter is enough and when you need a laboratory result.

The material, the size of the part and the hardness scale your drawing calls for decide which hardness tester you need. This guide works through metals, rubber and plastics, portable and bench testers, and what each method can and cannot do.

The metal under the coating and the thickest coating you expect decide which coating thickness gauge you need. This guide explains ferrous and non-ferrous probes, measuring ranges, and when you need a different instrument altogether.

Pipe diameter, inspection distance and whether you need to locate the camera underground decide which pipe inspection camera suits you. This guide explains the choices and where each type of system fits.
