The TE-5007 7-Day Mechanical Timer provides precise scheduling control for Tisch Environmental high volume air samplers. 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 robust mechanical timer operates on 110 volts, 60 hertz power and delivers reliable weekly sampling control for EPA-compliant ambient air quality monitoring.
Technical Operation
The male side of the ETI cord set plugs into the TE-5007 7-Day Mechanical Timer timed female cord, while the other female cord set on timer (on the right) is hot all the time and is an extra plug. The male cord set of timer plugs into the line voltage. This dual-outlet design allows connection of both timed equipment (such as motors and flow controllers) and continuously powered accessories.
