The Edgetech PDM75-X3 Hygrometer brings all the standard features of the renowned DewMaster Hygrometer into a rugged, portable package ideally suited for demanding field use. It delivers drift-free accuracy, NIST traceability, low maintenance, high durability, and exceptional ease of use in environments ranging from industrial plants to remote field locations.

The instrument features a modular chilled mirror sensor that is chemically resistant to background gases, allowing configuration to meet specific dew/frost point measurement requirements across a wide range of applications. Its best-in-class air-cooled temperature depression capability ensures reliable performance even in challenging environmental conditions without requiring external cooling resources.

The PDM75-X3 incorporates Automatic Balance Control mode, which automatically corrects for mirror contamination to maintain measurement accuracy and minimize maintenance intervals. Users can choose between remotely or locally mounted sensor configurations to optimize installation for specific applications.

This portable hygrometer is suitable for diverse applications including compressed air systems, furnace and heat treating processes, fluidized bed dryers, metrology and calibration, plastic molding operations, pharmaceutical manufacturing, laboratories and clean rooms, power and energy systems, and air brake dryer monitoring. The high-impact portable case protects the instrument during transport while maintaining accessibility for field measurements.
