The TE-5010-23 is a digital/resettable elapsed time indicator counter designed specifically for high volume air sampling systems. This universal voltage device operates on both 110V and 220V power at 50/60 Hz frequencies, making it suitable for international installations and diverse facility power configurations.
Technical Operation
An elapsed time indicator is a device that records and displays an elapsed time but performs no output function, serving as a critical monitoring component for EPA-compliant ambient air monitoring programs. The digital display provides precise time tracking with resettable functionality, allowing operators to monitor individual sampling periods while maintaining cumulative operational records.
Key Specifications
- Voltage: 110/220V universal input
- Frequency: 50/60 Hz compatible
- Display Type: Digital LED/LCD readout
- Reset Function: Manual reset capability
- Mounting: Standard panel mount configuration
Air Sampling Applications
A motor, timer, flow controller, elapsed time indicator, outdoor aluminum shelter, and pressure gauge form the core components of EPA-compliant air sampling systems. In integrated sampling, a sample is collected over a period of time, making accurate time measurement essential for calculating flow rates and pollutant concentrations. These systems are designed to meet the requirements described for sampling using US EPA method TO-4A, TO-9A, and TO-13A.
Compatibility
This elapsed time indicator integrates with Tisch Environmental high volume air samplers including:
- TSP (Total Suspended Particulate) samplers
- PM10 and PM2.5 particulate matter samplers
- PUF (Polyurethane Foam) samplers for volatile organic compounds
- Multi-metals samplers
- Custom sampling configurations requiring precise time documentation
Installation and Operation
The TE-5010-23 mounts directly into standard control panels and connects to the sampler's electrical system. ETI feedback allows operators to make adjustments for optimal use of time and resources. ETIs are common on machinery to monitor cumulative usage. The resettable function enables operators to track individual sampling events while maintaining long-term operational records for maintenance scheduling and regulatory documentation.
The need for preventative maintenance can be monitored with an ETI to help prevent downtime, making this device essential for maintaining continuous air quality monitoring operations required by NAAQS compliance programs.
