The AtmosRx Jr. is a smaller and more compact version of the original AtmosRx Vaporizer, making it even easier to vaporize while on the go. This Jr. version utilizes a smaller battery, heating chamber and mouthpiece. The AtmosRx Vaporizer is a hand-held, controlled consistent-temperature heating system designed to turn your favorite herbs into vapor. The AtmosRx operates well below the temperature required to burn tobacco through a process called vaporization. There's no combustion, hence no smoke. Instead, the AtmosRx gently heats just enough to release the essence of your favorite herbs. The process of AtmosRx vaporization or volatilization releases the essential, active elements of a substance without any burning. The AtmosRx uses a cutting-edge convection technology that releases just enough heat and air to discharge the vital elements; but not enough heat and air for the materials to combust.
