Hobbs HMD46 hour meters use a stepper motor for timing and are UL recognized and CSA certified.
The meter display reads to 1⁄10 of an hour, for up to 100,000 hr. The meters run quietly and feature a squared-face design. There are two mounting styles: stirrup or retainer, which interchange with most meters currently available. Potential applications include tracking elapsed time on dc-powered equipment such as generators, irrigation pumps, panel subassemblies and compressors.
