Introducing:  Model CA5000 Freezer Temperature Monitor, Alarm System (with Unique Liquid CO₂ Backup Injector Technology for Optimum Freezer Temperature Monitoring and Alarming.

Hampshire Controls Corporation's Model CA5000 is freezer temperature monitor and alarm system that also incorporates a unique liquid CO₂ backup injection. This systems provides ultimate security for freezer contents that must be continuously maintained at ultra-low temperatures. It's ideal for laboratory and other manufacturing applications.

The system offers user-programmable alarm and control set points, and alarm delay times. And all parameters are stored in non-volatile memory - so they are maintained even when power is lost.

The customer supplied liquid CO₂ is maintained at high pressure, ready to be injected into a freezer cabinet, enclosure or system. When a malfunction occurs and the freezer warms above the user-defined setpoint, a user-defined amount of liquid CO₂ is injected into the freezer.

The CA5000 is very simple to operate: plug in the unit, place the probe in the freezer chamber to be monitored, and the display will show the temperature of that location.  Pushing three buttons allows the user to program various alarm set points and controls. 

FEATURES:

* An internal battery with integrated charger keep the system running for at least 24 hours after a power outage.

* "BAT" indicator warns of a disconnected or low backup battery condition.

* Backup time of at least 8 hours on one standard cylinder of CO₂ at -60 °C setpoint.

* Independent user-programmable controls for system alarms and liquid CO₂ injection.

* Visible and audible indicators for system status.

* Multiple programmable alarms available to minimize nuisance or false alarms.

* Relay outputs for central alarm systems or automatic dialers.

* A door safety interlock switch prevents CO₂ injection while freezer is being accessed.
