All of the Black series are
-  Economic. Using standard type rechargeable AA batteries and low cost, reusable probes and sensors.
-  Small. Light, robust: Virtually no power is consumed when ‘off’ and the memory is non-volatile and removable.
-  Easy to use. Transfer the data in the lab and online for viewing and storage, using wireless communication or use the memory card to dump to the industry-standard oximetry/ capnometry software Visi-Download.
