Ambient Monitor

Because our WBMS is focused on the whole battery backup system it also keeps an eye on the conditions around the batteries - inside battery rooms and/or cabinets.

Wireless Ambient Monitor measures ambient temperature and ambient humidity. It can detect bad ventilation or faulty air conditioning and in conjunction with Wireless Battery Monitors recognises the first stages of the thermal runaway.
