The TA356-HC-40 color-change humidity indicator single spot disc detects relative humidity levels of 40% and will indicate such change by turning pink. This disc can be inserted into the TA356, TA350, TA354, TA359 and TA348 Humidity Indicator Plugs, which are each sold separately. AGM's TA356-HC-40 color change discs meet the requirements of SAE AS26860 and MIL-I-8835.
Additional humidity indicator single spot discs are available upon request, which measure relative humidity levels from 10% to 90%. Other humidity indicator color change discs are also available as pie sectors or spot type cards. Please contact AGM for more information about the different configurations that can be used in conjunction with the TA356 Humidity Indicator Plugs.
