Description
Compact Design for Space-Constrained Panels
The TA348 is a compact humidity indicator plug specifically designed for applications where panel space is limited. Its front-mount configuration allows for faster installation and removal.
Constructed from clear anodized aluminum, the TA348 is designed to fit a 3/4-14 straight pipe threaded boss. It comes supplied with an o-ring and a 40% relative humidity indicator disc.
For configurations with multiple humidity values, optional pie-sector discs are available. Suffix numbers in the part number denote the disc type. For example, TA348-234P includes a 20-30-40% pie-sector disc.
