Gas-phase Tank Data Collector Smart Read-Box

The Smart Read-Box is a data acquisition device designed for vapor-phase dewars from brands such as Thermo, MVE, Labserv, Haier, and SJ. It collects dual-point temperature and liquid-level data from the controllers of these liquid-nitrogen dewars. Equipped with a high-capacity, rechargeable lithium battery, it can operate continuously for more than one year on a single charge and is suitable for ambient temperatures ranging from –20°C to 50°C. During installation, it simply connects to the RJ-45/RS-485 interface of the dewar’s control system; after acquiring the data, it transmits the information to a relay unit at a fixed interval of every 10 minutes for storage.
