When exposure above a threshold occurs for long enough to represent a meaningful excursion, the corresponding indicator window changes permanently, providing a simple visual record that an out-of-spec temperature event has occurred.\u003c\/p\u003e\n\u003cp\u003eThe Duo format contains two thresholds in one unit, enabling a two-level indication that supports acceptance checks, quality investigations, and carrier accountability.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eDuo Threshold Model\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e10°C \u0026amp; 34°C (Duo thresholds)\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe WarmMark® Duo format provides two calibrated points of indication within one indicator to support more informative decision-making on receipt.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003ePack Options\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e10 Pack\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e100 Pack\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePharmaceutical and medical device shipments\u003c\/li\u003e\n\u003cli\u003eDiagnostics, reagents, and laboratory supplies\u003c\/li\u003e\n\u003cli\u003eTemperature-sensitive consumables and components\u003c\/li\u003e\n\u003cli\u003eCold chain lane testing and validation shipments\u003c\/li\u003e\n\u003cli\u003eQuality investigations and carrier performance review\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-level (Duo) temperature excursion indication in one indicator\u003c\/li\u003e\n\u003cli\u003eIrreversible visual record for compliance and documentation\u003c\/li\u003e\n\u003cli\u003eNo batteries, electronics, or calibration required\u003c\/li\u003e\n\u003cli\u003eSimple to apply and easy to interpret on receipt\u003c\/li\u003e\n\u003cli\u003eSupports acceptance checks, investigation, and accountability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eUse \u0026amp; Handling Clauses\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlacement:\u003c\/strong\u003e Apply the indicator to a clean, dry surface on the outside of the package where it can be inspected on receipt.
