RAMPTROL
Glas-Col’s LimiTrol limiting control provides a safety backup for laboratory heating processes. When installed between the primary power or temperature control and the power source, the LimiTrol allows for over-temperature limiting. The operator simply sets the LimiTrol to the maximum temperature for the process. Should the primary power control fail, or the process temperature be exceeded for any reason, the LimiTrol will terminate power to the primary control, thus reducing the chance of damage to samples, expensive equipment, and glassware due to overheating. The unit features a manual reset, which means power will remain off until the operator restores the system. The set-point dial is calibrated in 20° C increments, and the load and thermocouple receptacles are located on the back panel for easy access. Furnished with a type J immersion thermocouple with 6"-long stainless steel probe.

DIGITAL TIMER
The Glas-Col Digital Timer is a micro controller-based countdown interval timer with digital display. For use with mantles,heating tapes, ovens, and other resistive loads up to 10 amps. Also can be used with stirrers, vortexers, shakers, and other motor-driven laboratory equipment up to 10 amps load capacity.Four timing ranges may be selected from the front panel. At the completion of the timing cycle, a solid-state alarm will sound for 5 seconds. The power to the load receptacle is terminated at the end of the timing cycle. The timer will then reset to the preset starting time. The timing cycle may be interrupted by pushing the start/stop button.Timing will resume from the stopping point when timing cycle is restarted.
