🚦 Pre-Programmed Time-Temp Indicator
The Pre-Programmed Electronic Time-Temperature Indicatoris a compact, battery-powered monitoring device designed to detect temperature excursions during refrigerated storage, shipping, and distribution.
The indicator monitors temperature exposure over time and activates visual LED alarms when preset temperature and duration limits are exceeded. Its three alarm conditions help identify exposure to low temperatures, freezing conditions, and prolonged high temperatures.
Designed for temperature-sensitive products, this single-use indicator features a 30-minute start delay, self-adhesive mounting, and an internal battery. No external power supply is required.
Custom pre-programmed temperature thresholds and event settingsmay be available upon request.

📑 Certificate of Conformance available
This single-use electronic indicator identifies preset time-temperature excursions through LED alarms. It does not replace a continuous temperature data logger where detailed temperature records are required. Verify alarm thresholds, activation procedures, and suitability for the monitored product before use.

- Reacts at three temperatures and five time intervals
- Visible alert if the temperature drops below 2°C
- Second LED shows a further alarm if the temperature drops below -0.5°C
- Row of 3 LEDs alert when the product has been above 8°C for 2,4,6 and 8 hours
How to use
- To activate, press and hold the button for >3.5 seconds until the green ‘Power on’ LED flashes 3 times.
- Once the indicator has been activated, the "Power On" LED will flash every 8 seconds.
- The device starts monitoring temperature after the 30-minute start delay.
- If no temperature breach has occurred, the green ‘Power on’ LED will flash.
- When the temperature drops below 2°C for more than 30 minutes single event the red ’30 minute’ LED will flash. Additionally, falling below -0.5ºC for 10 m will flash the second ALARM LED.
- When the temperature rises above 8°C for more than 8 Hours cumulative, the red ’60 minute’ LED will flash.
