Digital timers keep track of timing; to trigger an action, to start timing once triggered by an action, or both. Some products are programmable while others may be fixed at a set internal time and function. In addition to the number and type of functions, these devices differ in terms of time range settings.
An hour meter is a gauge or instrument that tracks and records elapsed time, normally displayed in hours and tenths of hours. The majority of hour meters are used to log running time of equipment to assure proper maintenance of expensive machines or systems. This maintenance typically involves replacing, changing or checking parts, belts, filters, oil, lubrication or running condition in engines, motors, blowers, and fans, to name a few.
