Simplify Monitoring of Heat-Sensitive Products

Zebra LIMITmarker® heat indicator, manufactured by Temptime®, is a single-use 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. The indicating “window” on the label changes colour when the response temperature has been exceeded.

  • Provide Assurance to Your Customers

    Zebra LIMITmarker indicators give customers critical information about their heat-sensitive products. Meet your customer's needs and increase their satisfaction by providing them with easy-to-understand and clearly visible indications of heat exposure.

  • Quickly Identify Time-Temperature Endpoints

    Quickly identify time-temperature endpoints with clear visual indications. LIMITmarker F indicators change colour from white to pink or red within the specified response time to indicate it has reached endpoint. When LIMITmarker I indicators reach their endpoints, their centre circle will match or will be darker than the outer circle.

  • Response Times to Match Your Product's Profile

    Response times are critical for ensuring your product has not been exposed to excessive temperatures. Select the right response time for your product. LIMITmarker F is a delayed response indicator with a response time between 15 minutes and 2 hours, while LIMITmarker I is a quick response indicator with a response time within seconds to 15 minutes.
