6 Pack 11.81" One-Step Calibration Kit with 75% RH Humidity Control Pack | One Step Hygrometer Calibration, True 75% RH Standard, 24 Hour Fast Testing, Large 11.81" Bag, Digital & Analog Sensor Use

About this item

• ✅【STOP GUESSING YOUR HUMIDITY】This professional 6-pack 75% RH humidity control pack uses a precision salt solution to create a controlled 75% RH reference environment, allowing you to verify digital and analog hygrometers before trusting them inside your humidor or storage space. An uncalibrated hygrometer can be off by 5–10% RH, leading to moldy cigars, dried-out wrappers, cracked wooden instruments, stale tea leaves, or damaged collectibles.[Note: Hygrometer is not included in the package]
• ✅【TRUE 75% RH STANDARD】This humidity control packs is designed to stabilize at 75% relative humidity in a sealed environment, providing an accurate standard for hygrometer testing and calibration. It features a salt-free polymer fiber formula to ensure a clean process with no residue and no risk of corrosion. The breathable membrane helps control moisture transmission for consistent performance, while the tear-resistant outer bag enhances durability.
• ✅【UPGRADED LARGE HIGH-DENSITY BAG】The 7.87 × 11.81 inch extra-large one-step humidity calibration kit is designed with a large-capacity interior that easily fits large hygrometers, external probes, wired sensors, and digital humidity meters. The spacious design allows multiple devices to be calibrated at once, eliminating the need to run separate tests for each unit. Calibrate everything in one go, making calibration faster, easier, and more efficient
• ✅【EASY 3-STEP CALIBRATION】Simply open the sealed bag, place the hygrometer probe or sensor together with the unwrapped humidity pack inside, and fully zip the bag to ensure an airtight environment. Let it sit for 24 hours (place it in a room between 65–75°F). Note: If the hygrometer reading is not 75% RH, adjust it according to the deviation, then retest
• ✅【REUSABLE & LONG SHELF LIFE】Each 75% RH humidity control pack maintains effectiveness for up to 3 months once opened and up to 2 years in its original sealed packaging. Designed for multiple calibration cycles, it provides a cost-effective solution for ongoing hygrometer accuracy checks. Simply store in a cool, dry place to preserve optimal performance
