The Next Generation Cigar Oasis ULTRA 2.0 uses upgraded technology to measure and control the humidity accurately. The Cigar Oasis ULTRA 2.0 electronic cigar humidifier was designed to mount on the lid of the humidor (or on or under a tray) with minimum space requirements. The ULTRA 2.0 can be powered an outlet or using the internal, rechargeable Li-Ion battery. The fan pushes out humidity until the desired level is reached. When operating on outlet power it samples the humidity continuously. On battery power the unit goes to 'sleep' to extend battery life. It will sample the humidity every five minutes to make sure the humidity is correct. If not, it goes into control mode to adjust humidity. In both cases the control point is set to 70% humidity. The unit comes with a water cartridge and is ready to use out of the box. By adding the optional WiFi Module, the Cigar Oasis ULTRA 2,0 can be monitored and adjusted remotely via the web or phone app.
