OxyGuard Atlantic

Product Details

With four relay outputs and 8 set points. There will always be at least one relay output that can be used to give alarm if the oxygen level goes too low or the temperature too high. And since Atlantic measures both parameters and has logical linking you only need to use one relay.

Atlantic also has 8 timers that can be used for a number of purposes. For example, alarm can be delayed so that only a sustained fault results in alarm being given.
