A handheld force gauges are a tool any web handler should have. Forces are important in web processes (e.g., tension, nip forces), but many are not measured or directly controlled. A force gauge is vital to calibrate these mysteries. There are many levels of sophistication to force gauges, going from simple fish-weighing scales (see below), to mechanical push-pull gauges, to electronic load cells with digital output and recording. Look for a force gauge with a 25-50 kgf (50-100 lbs) range if you intend to use it by hand. Larger force gauges are useful for higher load measurement inline with a rope or cable (i.e., when not held by hand).
