Meets AS26860 Type II
The TA346 is a larger-format humidity indicator plug made from clear anodized aluminum. It is designed for installation through a 1.45 in. (37 mm) diameter hole in a flexible barrier. The plug comes supplied with a nut and two gaskets. For installation into a rigid container, one gasket can be removed and the nut reversed to secure it in place.
By default, the TA346 is equipped with a 20-30-40-50% indicator disc. Additional disc configurations are available upon special request.
Humidity indicator discs are field-replaceable using a 0.875 in. (22 mm) hex key wrench.
