It is essential to control the humidity levels in server rooms and enclosures: damp air can lead to condensation, corrosion or short circuits while dry air encourages static electric discharges. Keeping in the safe range requires a hygrostat, a device to monitor the humidity level and operate your humidity controllers as required. A good quality hygrostat responds quickly to changes in humidity so that your equipment can react in advance of issues rather than constantly playing catch-up.
