MVARIO2 is a system that measures atmospheric pressure and using the obtained data it calculates the altitude above the sea level, the speed, and the rate of climb as well as the rate of descent. Further on the extreme data (minimal and maximal values) are recorded, the change on climb and descent is signaled, and the sensor also alerts if the alarm setting is exceeded.
The data of the sensor are transmitted via the Duplex system to the user.
The Duplex system takes advantage of the 2,4GHz band for communication, which does not only transmit model control data to the model, but is also sends the data from the model back to the transmitter. The telemetric data gained during the operation are shown as actual measured values in real time on the LCD screen of the JETIBOX or on the DC/DS JETI model transmitters.

Main features:
- Measurement of altitude, pressure, and temperature.
- Very accurate and fast indication of climb and descent.
- Possibility of sound alarm signalization using Tx module or JETIBOX profi.
- Possibility to be used as Expander and to connect other sensors.
- Adjustable compensation of energy (TEK) via MSPEED EX sensor.
- Possibility to be used as an altitude switch in FAI F5J or ALES competition categories.
- The device is compatible with EX Bus protocol, i.e. it is possible to be configured comfortably via a special menu in DC/DS JETI model transmitters.
- Firmware updates.
