Minco wall/duct humidity detector assemblies are temperature compensated, compact and lightweight. They are designed for use in air ducts and plenums. They feature an integrated circuit sensor with a stable polymer element that is encapsulated by a sintered stainless steel filter, plus an advanced microprocessor to provide accurate and repeatable measurements. Temperature output is optional.
