All portable instruments from ENMET are battery powered. They type of battery, capacity and charging techniques vary from instrument to instrument. Care should be taken to charge an instrument's batteries as instructed. This includes charging time and using the proper battery charger. Failure to do so could damage the charger, the battery pack or both.

Stationary instruments and compressed air line monitors can be supplied with battery back up systems. An ENMET installed back-up system has a built-in charging circuit that will charge a fully depleted battery in 8-16 hours typically depending on battery capacity.

Consult ENMET for further details on specific applications.
