ETF200 Hygrostat

This relative humidity hygrostat is available as pre-set, ETF200, or adjustable, ETF2000. It activates a device, such as a heater, within the enclosure, either at the pre-set level, 65%, when the relative humidity has been exceeded, or at a level set by the user, which could be between 40-90% humidity.

Features

Feature:

Fixed (ETF200) or adjustable (ETF2000) relative humidity hygrostat, with a normally open (NO) contact.

Advantage:

The pre-set hygrostat allows energy to flow to a device (normally a heater) when the 65% relative humidity setting has been exceeded (ETF200). The adjustable hygrostat allows energy to flow to a device (normally a heater) when the relative humidity level that the user has set, has been exceed, this will range between 40-90%.

Benefit:

The installed devices, such as fan heaters, automatically turn on or off when they are required, which reduces the operational cost of the control panel. Managing the relative humidity within the enclosure will prevent water condensation from occurring.
