SEC-Le v4 Multi-function Laboratory Gas and Electric Control System
The SEC-Le is a multi-function solution designed for the laboratory. Providing the operator individual control of the Gas and bench electric supplies.

Gas Pressure Proving
Featuring Medem’s patented differential pressure proving method it can pressure prove a variety of gas delivery lines including oxygen up to 10bar. Overpressure can also be monitored and reported on the LCD display.
The SEC-Le can monitor the carbon dioxide level and temperature to control area ventilation in the laboratory when fitted with appropriate sensors.
Where the CO2 level rises above prescribed limits, the system can isolate a gas supply to help meet the updated BB101 and IGEM/UP11, edition 3. The limit is variable to accommodate for current legislation and guidance.
The fail-safe gas valve and relay checking, fire alarm and time delay auto restarts are just some of the new developments making Medem systems continue to be the most reliable, safest and flexible available today.
