Time-Tracker Elapsed Time Indicators

The Fredericks Time•Tracker Elapsed Time Indicator is a glass, direct-reading device for accurately measuring actual elapsed operating hours of any electrical instrument, equipment, appliance, or component. Readings are permanent, non-reversible and tamper-proof. Its solid construction provides maximum resistance to severe shock, vibration and other potentially damaging conditions.

The Time•Tracker is readily mounted in an open fuse clip, custom fuse holder, or modular package. With optional pigtail leads, the Time•Tracker is ideally suited for PC-board mounting.

This economical, mercury-free elapsed time indicator requires less than .25 watt. It employs a patented, heavy duty copper electrolyte. Elapsed time is recorded by the precise increase in linear length of an easy-to-read copper column in the calibrated glass tube. The Fredericks Time•Tracker measures time spans up to 20,000 operational hours.
Typical applications include: warranty recording, aircraft instrumentation, antennae, computers, electronic equipment, marine engine service, transportation, and utilities.
