Integra Boost Humidity Indicator Cards Read a Span Rather Than a Setpoint
This is measurement rather than control, and the distinction matters before anything else. A card carries printed indicator spots that change color against a scale. The scale runs from 10% to 60% RH, so a card reports where a container actually sits rather than signalling one event. Ten cards go in each pack and 36 packs make the master case, for 360 in total. Using one takes no equipment: put a card in the sealed container, leave it to settle, then read the spots. That is a different job from the replacement card packed inside a retail pack wrapper. That card marks a pack as spent. This one gives you a number.
Indicating Cards for Storage Containers, and the Line at 60%
One limit decides where these belong, so it is worth stating plainly. The printed scale stops at 60%. A container held at 62%, 69% or 72% reads at the top of the card rather than at a value. That makes it no help for confirming those setpoints. Where the cards earn their place is everything below that line. A drying room coming down through the fifties is exactly the window they cover, along with a 55% storage container or a desiccant-dried tote. They also suit a bench that wants a reading in ten containers at once without ten meters. For a container held above 60%, a hygrometer is the honest tool. Case quantity is what makes that kind of routine checking practical.
Key Features
- Reads 10% to 60% RH: A printed span rather than a single trip point, so a card reports where a container sits.
- Ten Cards Per Pack: Enough for a run of containers without breaking into the rest of the case.
- 360 Cards Per Master Case: Case depth for a room checking many containers on a routine rather than occasionally.
- No Power and No Calibration: Place a card, let it settle, read the spots. Nothing to charge and nothing to zero.
- Measures Rather Than Controls: These report humidity. Holding a setpoint is the job of a two-way pack.
- Different From a Replacement Card: The card in a retail pack wrapper marks a spent pack; this one gives a reading.
- Scale Stops at 60%: A container held at 62% or above reads at the top of the card rather than at a number.
- Suits Drying and 55% Storage: The covered span lines up with dry rooms and the drier storage tier.
- Flat Card Format: Sits against a container wall or lies on top of contents without taking usable volume.

Do These Control Humidity?
No. They report it. A two-way Boost pack is what holds a container at a setpoint, and the two are used together.
Will a Card Read a 62% Container?
No. The printed scale stops at 60%, so anything held at or above 62% reads at the top of the card rather than at a value.
How Is This Different From the Card in a Pack Wrapper?
That card signals when a pack is spent. This one reads the humidity in the container across a 10% to 60% span.
How Long Does a Card Take to Read?
Give the container time to settle after sealing. A card reports the air around it, so a reading taken immediately is a reading of the room.
