The Grässlin GZ Series DC Hour Meters are the answer to applications requiring low power load usage metering. Compact,
tamperproof GZ40 meters are sealed against the environment (IP rated up to IP66) to provide years of service. Accumulated load
usage hours are stored in the mechanical indicating counter; therefore, no battery is required to maintain elapsed time. An input
diode provides polarity protection. A quartz crystal time base ensures accurate, long-term timekeeping.
No electrical connection required. The RZ Series Vibration Hour Meters convert vibrations into
energy to drive the minute hand. This sensitive hour meter can operate from the slightest vibrations,
such as a moving car. Horizontal or vertical mounting position to 45º.
