For electronics areas, humidification is used to keep RH in a range where static risk is reduced without creating condensation.
The RH setpoint should follow the factory process requirement. Avoid chasing a high number if the space has poor air distribution.
Do not place the sensor directly in the mist stream. It should read the working area, not the outlet.
Use suitable water quality and schedule cleaning. Dust or mineral carryover is not acceptable around electronics production.
Project note: Confirm workshop size, target RH, ventilation, sensor location and water standard before selecting module quantity.
