1 Product description

DOL 104 is a high-precision sensor for measuring relative humidity. It is intended for use in livestock houses

but is also well suited for a number of industrial applications.

The sensor features one analogue output with full protection against short-circuits and wiring failures.

The special sensor element and the built-in Teflon filter enable application in livestock houses with constantly

high humidity.

The sensor is microprocessor-controlled and has a two-color light emitting diode (LED) to communicate the op-

eration status and the error diagnostic.
