Timestrip neo Cold Chain Indicators
TT525-DF
For products requiring a standard chilled range (e.g. 2 – 8°C), the Timestrip® neo Fridge Alarm alerts for freezing conditions, chilling below the minimum threshold, and damaging warm excursions, often tracking cumulative time above the set range for total confidence.
Temperature Thresholds: Alarms when temperatures drop below 0ºC, 2ºC and rise above 8ºC
Size: 22.6mm x 42.3mm x 5.6mm

TT525-AB
Provides critical, triple-threat monitoring for sensitive 2 to 8°C chilled goods. It uses clear, irreversible LED alarms to instantly flag freeze (below -0.5°C), low chill (below 2°C), and cumulative warm (above 8ºC) excursions.
Temperature Thresholds: Alarms when temperatures drop below -0.5ºC, 2ºC and rise above 8ºC
Size: 22.6mm x 42.3mm x 5.6mm

Timestrip neo FAQs
Timestrip neo
Timestrip neo is a smart electronic indicator technology designed to monitor temperature and/or time in various applications. Products in the neo range provide visual indications when a specified threshold has been reached.
Timestrip neo indicators are built on a unique electronic design platform combining accuracy with robustness, small form factor and low cost. It uses an internal sensor and clock to measure temperature and time, and features LED lamps for indication of condition.
Timestrip neo has a wide range of applications across industries such as food and beverage, healthcare, pharmaceuticals, and industrial manufacturing. It is commonly used for monitoring product freshness, shelf life, expiration dates, and adherence to safety protocols.
No, one of the advantages of this simple indicator is its intuitive use procedure, making it suitable for use all along the supply chain.
The standard Timestrip neo is a single-use device. However, Timestrip neo Multi can be reset and used up to five times using a special reset device available from Timestrip. The Timestrip neo Multi is the industry’s first resettable electronic temperature and time indicator.
Timestrip neo is accurate to within 0.5ºC, more than accurate enough for intended applications, and more accurate than liquid-based indicators. Accuracy is checked against NIST® traceable standards.
Since the introduction of the standard temperature indicating device, other products with more complex functions have been introduced. For example, the TT525-DF, designed for Fridge monitoring, shows an alert if the temperature falls below 2ºC and another at 0ºC, but also indicates how long the device has been exposed to conditions above 8ºC with three time intervals.
Yes, Timestrip neo is available in several standard configurations, but special temperature and time thresholds can be ordered for reasonable minimum quantities. Customization options include the duration of breach, visual indicators and product branding.
As a battery operated product, Timestrip neo must be disposed of in a responsible fashion. neo Multi, being multi-use, can reduce the disposal of used indicators by up to 80%. Efforts are made to minimize waste during production, and there are options for recycling depending on local regulations.
Yes, the small and light smart labels are easily stuck onto inner or outer packaging, or enclosed within a parcel.
Timestrip neo offers several benefits, including improved product quality control, enhanced safety measures, streamlined inventory management and enhanced customer satisfaction by ensuring product freshness.
Timestrip neo offers models specifically designed for cold chain monitoring, ensuring that temperature-sensitive products maintain their integrity throughout the distribution process. These products can withstand low temperatures and provide accurate time monitoring even in refrigerated or frozen environments.
While Timestrip neo is versatile and reliable for many applications, there may be limitations in extreme environmental conditions. Neo is specified to operate from -10ºC to +60ºC. Please see the specification for the product or consult with Timestrip experts to ensure compatibility with your unique requirements.
No, the battery is sealed inside the device.
Yes, Timestrip neo is suitable for various medical applications, including monitoring pharmaceutical products, timing the expiration of medical devices, tracking the shelf life of medicines and ensuring compliance with sterilization protocols. It helps healthcare professionals maintain quality standards and patient safety.
Activation times for Timestrip neo can vary depending on the specific model and application requirements. The standard specification is for a 30 minute delay after activation, while the indicators are attached to packaging etc. Refer to the product specifications for precise activation instructions.
Timestrip neo can be customized to monitor product warranty periods, alerting consumers or service technicians when the warranty period is about to expire, or when a service is due. This helps manufacturers and retailers manage warranty claims, and provides customers with timely reminders for warranty renewals or service inspections.
Timestrip neo labels are designed to withstand a wide range of storage conditions typical for their intended applications. However, it's important to store them in a clean, dry environment away from direct sunlight and extreme temperatures to ensure optimal performance and longevity
Yes, Timestrip neo can be customized for various industrial applications, including tracking the expiration of chemicals, reagents, or other time-sensitive materials used in laboratories, manufacturing facilities, or research environments. Customization options ensure compatibility with specific chemical properties and handling requirements.
