7-Day Mechanical Timer, 220 Volts 50 Hertz SKU: TE-5007X

The TE-5007X is a 7-day mechanical timer engineered for international high volume air sampling applications operating on 220 volts, 50 Hz power systems. Recognized by its bright yellow timer dial, the 7 day mechanical timer uses a series of on/off trippers to set the sampling schedule. This reliable timing mechanism provides precise start/stop control for TSP, PM10, and PM2.5 high volume air samplers in EPA-compliant ambient air quality monitoring applications.

Technical Operation

The TE-5007X operates on a simple yet dependable mechanical principle. The timer uses a series of on/off trippers to set the sampling schedule across a seven-day cycle. Users position plastic trippers around the yellow timer dial to program when sampling begins and ends. The mechanical clock drive rotates continuously, activating and deactivating the connected sampler based on the tripper positions. This design provides reliable operation without dependence on electronic components that may be susceptible to power fluctuations or electromagnetic interference.

Key Specifications

• Voltage: 220 volts, 50 Hz (international power systems)
• Timer cycle: 7-day repeating schedule
• Programming: Manual tripper positioning
• Minimum on/off interval: Typically 2-hour increments
• Visual indicator: Bright yellow timer dial

Sampler Compatibility

The TE-5007X integrates with Tisch Environmental's complete line of 220V, 50Hz high volume air samplers, including:

• TSP (Total Suspended Particulate) samplers for 40 CFR Part 50, Appendix B compliance
• PM10 samplers meeting 40 CFR Part 50, Appendix J requirements
• PM2.5 samplers for 40 CFR Part 50, Appendix L applications
• Both Mass Flow Controlled (MFC) and Volumetric Flow Controlled (VFC) sampler configurations
• Brush-style and brushless motor assemblies

Installation and Operation

Mount the TE-5007X timer on the sampler shelter door or control panel for easy access during routine maintenance. The mechanical design requires no calibration or electronic setup. To program sampling schedules, simply position the included trippers around the timer dial at desired start and stop times. Settings are repeated every 7-days, making it ideal for routine monitoring programs with consistent weekly sampling patterns.

International Applications

The 220V, 50Hz configuration makes the TE-5007X suitable for air quality monitoring installations worldwide, particularly in Europe, Asia, Africa, and other regions using 50Hz power systems. Applications include ambient air quality monitoring for regulatory compliance, industrial emission monitoring, and environmental research programs requiring reliable, long-term particulate sampling schedules.
