Four-level humidity indicator for large storage and missile containers: 20, 30, 40 and 50% RH. Black anodised aluminium alloy, 1-7/16–18 UNEF mounting thread; compatible with AD302 panel bush and HUMS devices using Arcadia holders.
Description
The AD301 is designed for large storage and missile container applications, where clear indication is available when containers are stacked in warehouses or missile silo facilities. The AD301 indicator has four levels of humidity indication — 20, 30, 40 and 50% RH — in a pie formation. Having four levels of indication allows more time to monitor desiccant adsorption during storage or field use, so that the desiccant can be changed at the optimum point.
The AD301 Humidity Indicator is specifically used by customers whose containers require a Health & Usage Monitoring System (HUMS) device. Arcadia has worked with many prime Defence Contractors to develop a holder to fit a HUMS device into the rear of the AD301 Humidity Indicator. With the additional use of the AD302 panel bush, the AD301 Humidity Indicator and mounted HUMS device can be removed without opening the container, allowing the data to be interrogated quickly and easily.

The AD301 is compatible with NEMA 1, 2, 3, 3R, 3S, 4, 5, 6, 12, 12K and 13 enclosures, as well as IP66 and IP67 rated enclosures. It may also be suitable for other NEMA or IP-rated enclosures depending on the specific application.
