This electrically-driven analog hour meter has an attractive black face plated with a chrome bezel. This gauge mounts into a 1 3/4-in to 2-in opening and provides a precise record for determining the operating period of an engine in elapsed hours. This meter is most commonly used for monitoring running time of off-road vehicles and machinery, maintenance scheduling, warranty, rental use time, and service records. The operating time is indicated in hours and tenths up to 100,000 hours, works on 12 to 24-volt systems, and includes mounting brackets.
