Reversible Humidity Indicator Card MS20003-3

MS20003-3 Reversible Color-Change Humidity Indicator CardThis Humidity Indicator Card is a color-change indicator and is reversible as required by Military Specification MIL-I-8835.  It also meets MIL-P-116 Method II requirements.  As the humidity increases, the chemically impregnated spots change from a blue color (DRY), through a lavender, to a pink color (HUMID).  As the humidity decreases, the spots change from a pink color (HUMID), through a lavender, back to a blue color (DRY).  The MS20003-3 is accurate to ±5% relative humidity (RH) at 75°F (24°C).  Other humidity combinations are available by special order.

NOTE: This card has been impregnated with a chemical that may cause corrosion of some metals; therefore AGM recommends that the card not be placed in direct contact with metal objects. 

This card is used where space may be a problem.  It is identical in design to the MS20003-2, except it is approximately 1/4 its size, making the MS20003-3 ideal for small package applications.  NSN # 6685-01-008-7563.

Size: 1" w x 1-5/8" h
