The Digi-Sense WD-03313-06 Easy-to-read card is ideal for use with bottles, chemicals, plastic bags, electronics, dessicators, and storage containers. Maximum range (highest humidity attained when exposed for 24 hours or more) is 50 to 90% RH - orange dot indicator changes to yellow in increments of 10% RH. Maximum memory range is readable to an accuracy of ±5% RH at 75°F (24°C).

Reversible current humidity (0 to 100% RH) changes color from blue to bright pink in increments of 10% RH; accuracy of ±2.5% RH at 75°F (24°C). Card arrives ready for use - each card is individually sealed in a clear moisture-barrier bag with dessicant to keep the card dry and provide for an extended shelf life. Traceable products are calibrated to NIST-traceable standards and ready to use as soon as you receive it.

The WD0331306 goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately. NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.
