LIMITmarker® Heat Indicators
LIMITmarker is a single-use heat indicator that shows a clear, irreversible signal when the product is exposed to sudden spike in temperature over a set period of time.
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 heat 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 label 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.
Use of LIMITmarker Heat Indicators
LIMITmarker heat indicators 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.
- To communicate their commitment to cold chain best practices.

FAQs- LIMITmarker Heat Indicators Supplier in India
What are the best heat indicators for cold chain monitoring in India?
Zebra’s LIMITmarker heat indicators supplied by Lisaline Asia are one of the best heat indicators for cold chain monitoring in India. They are self-adhesive, and offer continuous temperature monitoring throughout storage and shipment. These indicators change colour from white to red/pink when the product is exposed to a sudden spike in temperature for set period giving immediate clear visual proof of heat exposure. They are compliant with international standards, making them a reliable choice for pharmaceutical, medical, and cold chain applications where temperature integrity is critical.
How do heat indicators like LIMITmarker work for pharmaceuticals?
Lisaline Asia supplies heat indicators like LIMITmarker are applied directly to the packaging, vials or boxes of pharmaceuticals. Made with heat fusible materials that melt and trigger an irreversible colour change (white to red/pink) when the pharmaceuticals exceed their safe thresholds. This provides a clear visual signal of heat exposure signalling the potency of pharmaceuticals has been affected.
Are LIMITmarker supplied by Lisaline single use disposable labels?
Yes. LIMITmarker® indicators supplied by Lisaline are single‑use, disposable labels. They are self‑adhesive, miniaturised heat indicators that provide an irreversible visual signal of sudden spike in temperature and are not designed to be reused.
Which are the top companies providing heat indicators in India?
Lisaline Asia is one of the leading providers of heat indicators in India. They are the official licensed supplier of Zebra’s LIMITmarker heat indicators in India. LIMITmarker heat indicators display a clear visual signal when the label irreversibly changes colour from white to red/pink upon exposure to a sudden spike or increase in temperature for a set time. This makes them ideal for monitoring heat-sensitive products in pharmaceutical, medical, and cold chain applications.
What are heat indicators like LIMITmarker used for?
Heat Indicators like LIMITmarker are used for monitoring sudden spikes in temperature for a certain period of time during shipment or storage. They are used to monitor whether the product has been exposed to sudden heat due to which its potency may have been damaged. They are used for temperature monitoring of cold chain products like pharmaceuticals, medicines.
Why choose Lisaline as your LIMITmarker supplier in India?
Lisaline Asia is the official supplier of Zebra’s LIMITmarker heat indicators in India. In a market full of unlicensed suppliers offering unreliable products, Lisaline stands out as an authentic, licensed provider of temperature indicators. Our LIMITmarker heat indicator labels give a clear visual signal when exposed to a sudden temperature spike for a set time. These single-use, irreversible labels change from white to pink/red, signalling that the product’s potency has been affected. Other heat indicators in India may not deliver such reliable results. Choosing Lisaline ensures guaranteed accuracy, helps you meet regulatory compliance requirements, and provides audit-ready proof of temperature exposure for pharmaceutical and cold chain operations.
How long does a LIMITmarker label remain active on a product?
A LIMITmarker label stays active and functional for the product’s entire shelf life, providing continuous temperature monitoring throughout shipping and storage from the moment it is applied until the product is used or discarded.
What is the difference between HEATmarker and LIMITmarker?
HEATmarker is a time temperature indicator label that gradually changes colour irreversibly with heat exposure over a period of time. The shades of the label get darker with more heat exposure until it reaches the darkest shade. LIMITmarker on the other hand is a heat indicator that triggers an irreversible immediate colour change from white to red/pink when there is a sudden spike in temperature for a set time. HEATmarker is used to monitor cumulative heat exposure while LIMITmarker is used to monitor sudden immediate heat exposure. Both temperature indicators are supplied by Lisaline Asia who are the official supplier of Zebra’s temperature indicators in India.
What are the different types of LIMITmarker labels?
LIMITmarker heat indicators are categorised based on response time and heat threshold temperature. The two major types are LIMITmarker I™ and LIMITmarker F™. LIMITmarker F labels respond within 2 hours when exposed to temperatures between 9°C and 31°C depending on the specific variant. They change color from white to red/pink. The delayed response helps avoid false alarms from brief temperature fluctuations. LIMITmarker I labels respond within 15 minutes when exposed to high heat thresholds. They change from white to red/pink or grey to black based on variant type. LIMITmarker F provides a delayed indication while LIMITmarker I provides immediate indication.
