EL-WiFi-TP Thermistor Probe Datalogger - Lascar

WiFi-TP WiFi Temperature Probe Data Logger
Professional temperature monitoring for refrigerators and freezers

The WiFi-TP temperature data logger accurately measures the temperature at the location of the external probe. Measurement data is transmitted wirelessly via the local WiFi network and can be easily viewed on a PC, smartphone, or through an online cloud platform.

Thanks to its internal memory, all measurements are safely stored even during temporary WiFi network interruptions. This makes the logger ideal for applications where continuity and reliability are essential, such as cold rooms, medical refrigerators, hospitality, and food storage.

✅ Most recommended logger for refrigerators & freezers

Data logger outside the refrigerator – sensor inside

This WiFi temperature data logger is specifically designed for refrigeration and freezer applications.
The data logger itself is installed outside the refrigerator or freezer, while the temperature sensor is routed inside via a cable feed-through or along the door seal.
👉 A refrigerator installation kit can help ensure a neat and safe installation.
