Digital Resettable Elapsed Time Indicator, 110/220V 50/60Hz SKU: TE-5013

The TE-5013 Digital Resettable Elapsed Time Indicator (ETI) monitors, records, and displays the passage time for powered equipment in high volume air sampling systems. This component works with Tisch Environmental mass flow controllers and sampling systems to register elapsed time while controlling constant flow rates, providing critical operational data for EPA-compliant ambient air monitoring applications.

Technical Operation

As an electronic ETI, the TE-5013 provides compact, accurate timing with easy integration into various systems. The digital display shows accumulated runtime, while the reset capability allows operators to zero the display for new sampling periods or maintenance cycles. The unit measures total operational time of monitored machinery, enabling estimates of wear and tear on equipment.

Key Specifications

• Dual voltage operation: 110V and 220V AC
• Frequency: 50/60 Hz compatible
• Digital display with reset function
• Suitable for continuous duty applications

Compatibility

The TE-5013 ETI integrates with Tisch Environmental high volume air sampling systems including:

• TE-5007 7-Day Mechanical Timer systems - the ETI plugs between the mass flow controller and mechanical timer
• Mass flow controller and digital timer combinations for line voltage connection
• TSP, PM10, and PM2.5 high volume air samplers used by environmental professionals for regulatory monitoring and research projects
• PUF sampling systems for pesticide and semi-volatile monitoring according to TO-4A, TO-9A, and TO-13A methods

Maintenance and Operation

The ETI enables monitoring of preventative maintenance needs to help prevent equipment downtime. Runtime data supports warranty compliance for equipment manufacturers who specify operating hours rather than calendar time. The reset function allows operators to track sampling periods, maintenance intervals, or specific monitoring campaigns.

Applications

Tisch Environmental ETIs support high volume air sampling for particulate, metals, volatiles, and specialty monitoring equipment. Applications include lead sampling, particulate monitoring, pesticide sampling, total suspended particles, and Federal Reference Method PM-10 and PM2.5 monitoring. The dual voltage capability makes the TE-5013 suitable for international installations and diverse power infrastructure requirements.
