Cermet II with 10 ft. cable and NEMA 4 Enclosure and NEMA 4 Front Cover
The Kahn Cermet II dewpoint monitor measures moisture from -100° to +20°C dewpoint in compressed air and other gas streams. The Kahn Cermet II Hygrometer consists of a digital display with integral signal conditioning board, ceramic dewpoint sensor and an interconnecting cable. The sensor can be installed directly in the gas line or in a separate sampling gas stream by utilizing the optional sensor block. The display can be easily mounted in a control panel or other appropriate location.
