TE-5012 Mechanical Elapsed Time Indicator (ETI) 110V 60Hz SKU: TE-5012

The TE-5012 is a mechanical elapsed time indicator (ETI) that registers how long high volume air sampling systems operate, displaying accumulated runtime in hours and tenths. This mechanical hour meter provides precise documentation of sampler operating time for EPA compliance monitoring and maintenance scheduling.

Operation and Display

The TE-5012 functions as an hour meter, documenting the running time of powered equipment in air sampling applications. The mechanical design provides robust performance suitable for harsh outdoor environments, though it may have slightly less precision than digital alternatives. The analog display remains clearly visible outdoors and retains values during power interruptions, making it ideal for remote monitoring locations.

• Voltage: 110V AC, 60 Hz
• Display: Mechanical analog readout in hours and tenths
• Type: Non-resettable accumulated time display
• Mounting: Standard electrical enclosure

System Compatibility

The TE-5012 connects in-line between mass flow controllers and mechanical timers in Tisch Environmental PM10 and TSP sampling systems. The ETI receives power through its female cord end and passes timed power to downstream components through its male cord connection to TE-5007 7-Day Mechanical Timers.

Compatible with these Tisch Environmental systems:

• TE-6000 Series PM10 High Volume Samplers
• TE-6070 Series PM10 Samplers with mass flow controllers
• TSP and PM2.5 sampling configurations
• Systems using TE-5007 mechanical timers and TE-5009 continuous flow recorders

Applications and Compliance

ETIs are essential for maintenance scheduling and provide insight into operational reliability, especially for equipment requiring regular maintenance and upkeep. This mechanical hour meter supports US EPA Reference Method compliance monitoring per 40 CFR Part 50, Appendix J by documenting exact sampling durations required for ambient air quality assessment.

Hour meters are commonly used on industrial equipment with motors to monitor cumulative usage, making the TE-5012 valuable for:

• EPA-compliant ambient air monitoring
• Maintenance interval tracking for brush-style motors
• Sampling duration documentation for regulatory reporting
• Equipment utilization analysis

Voltage Variants

Tisch Environmental offers voltage-specific models for different power requirements. The TE-5012X (220V 50Hz) and TE-5012XZ (220V 60Hz) provide identical functionality for international applications or systems with different electrical specifications.
