LIMITmarker®

Threshold heat Indicators

LIMITmarker ™  heat indicator is a single-use heat indicator that can be applied directly to
heat-sensitive products. LIMITmarker™ provides an easy-to-read, irreversible visual signal within
the specified response time that heat exposure at or above the response temperature has
occurred. It is adhesive-backed and can be applied directly to product surfaces or packaging.

LIMITmarker F™ Indicator – Delayed Indication

LIMITmarker™ F is a threshold heat indicator with delayed indication. It is the most convenient device for monitoring product temperature during short term storage and shipments.

When LIMITmarker™ F indicators are exposed to temperatures at or above the response temperature, the window changes color to pink or red within the specified response time of 2 hours. The appearance of any pink or red in the window means that the indicator has reached “endpoint.”

LIMITmarker I™ Indicator – Immediate Indication

 

LIMITmarker™ I is a threshold heat indicator with immediate indication. It is the useful device for monitoring product temperature during short term storage and shipments.
LIMITmarker™ I, a high heat threshold indicator that monitors temperature and immediately indicates when the heat exposure, at or above the response temperature is exceeded.  If the color of the centre circle matches or is darker than the outer circle, the ENDPOINT has been reached indicating that the predetermined threshold heat profile has been exceeded. 

When LIMITmarker™ I indicators are exposed to temperatures at or above the response temperature, the centre circle will match or will be darker than the outer circle, the ENDPOINT has been reached within the specified response time.

Use of LIMITmarker™ Indicators

LIMITmarker® with adhesive-backing, can be applied directly to product surfaces or packaging.
Leading manufacturers and distributors use LIMITmarker™ heat indicators on temperature
sensitive medical products
• To ensure compliance with regulatory guidelines
• To extend their quality systems into the distribution system and
• To communicate their commitment to cold chain best practices.
