Integra Boost Humidity Indicating Cards 10% to 60%. Qty 10 per pack, Master Case of 36 packs. 360 Total Qty.

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.

Documentation ISO and QPL documentation available from the manufacturer on request SKU 04IB14C29 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.
