TA348 Humidity Indicator Plug
The TA348 has a smaller “footprint” and is used where panel space is limited. The front mount design reduces installation and removal time.
This clear anodized aluminum Humidity Indicator Plug is designed for installation in a 3/4-14 straight pipe threaded boss. Furnished with an o-ring and a 40% humidity disc.
For optional multiple spot discs, refer to the chart below. Suffix numbers specify optional discs. For instance, TA348-234P includes a 20-30-40% pie sector disc.
