LIQUIDTOOL analyzes the characteristics of lubricating fluids in industrial machinery and optimizes their use, allowing production to proceed continuously, safely, and consistently during machine operation. The device's main component collects, analyzes, and returns the fluid to the machine, adjusting its parameters and supplying a token that communicates data via RFID connection to the smartphone. Both the main device and token are equipped with magnets for easy mounting and removal on the machine without impacting its structure. The device is also equipped with LED lights that already communicate the machine status from a distance through various light signals.
