Temperature journey recording & reading
The TL520 is a temperature sensitive indicator and data logger ideal for refrigerated temperature shipping. The single use device provides an immediate irreversible indication of over- and under-temperature conditions using built-in LED lights. TL520’s alarm status is always visible. The TL520 can log and store up to 3800 temperature data points.

Why choose TL520?
Many temperature sensitive data loggers for shipping are expensive and require computer software and training to use. Not Timestrip TL520!

TL520 can be read with an NFC enabled smartphone via our app. You can export data from the app to PDF or Excel for evidence of temperature breaches. For quick visual indication of temperature excursions, single use TL520 can be read simply viewing the flashing LED lights. The status light blinks every 30 seconds. This means everyone along the cold chain can check the status of the shipment, without any special training or equipment.
Why Micro Data Loggers?
Single Use
Irreversible LED alerts to both upper and lower temperature breaches. No need to return base for analysis or reuse.
Free Mobile App
Logged data can be read by wirelessly downloading to a free temperature monitoring app via NFC technology. Reports can be created into a PDF to send or save to phone.
Product Level Monitoring
These Micro Data Loggers are small enough to monitor individual products within a shipment.
Carbon Footprint
Low power TL520 helps to control the environmental impact of the supply chain as part of a well-managed quality control system.
