The W-510 1000W powerful fogger's precision lies within the optoelectronic liquid sensor (OPTO). Production of fog will cease when the machine senses there is insufficient liquid and then start again when it senses the re-filling of the liquid. This light, sleek, and compactly designed fogger is equipped with DMX on-board. Each wireless receiver can memorize up to 5 sets of frequencies and all receivers can receive signals from any registered transmitter. Wireless range is up to 50M (meters). Wireless distance may vary depending on the interference. One wireless controller comes standard.
