NODE, WiFi Thermometer with Internal and 2 External Probes
Straightforward WiFi temperature monitoring for multi-level storage
Secure your cold storage data by connecting your NODE device directly to your WiFi network. Your readings are safely stored in the cloud, allowing you to log in from any location to track data, view reports, and maintain a digital paper trail for MHRA or HACCP audits.
What sets this model apart is the inclusion of two external ports alongside the internal temperature sensor. This dual-probe setup allows you to monitor two separate areas simultaneously - such as two different shelves within a fridge or multiple levels of a vivarium. It is compatible with our glass bead food simulant probe, which mimics the temperature of your products rather than the surrounding air to stop false alarms when doors are briefly opened. All NODE models are supplied with a UKAS calibration certificate.
Configuring your logger is simple through any web browser. You can personalise the device name, adjust the reading frequency, and assign specific high and low temperature limits for each individual sensor. Should you experience a mains power cut, the built-in battery ensures your data continues to record without interruption.
The 2-port NODE is designed for
Commercial Fridges and Freezers - Ensure HACCP compliance across cold storage units. Safely track active produce, raw materials, specialised chilling systems, and industrial refrigeration processes.
Laboratories and Medical Facilities - Maintain tightly controlled climates for sensitive clinical environments. Dependably monitor temperature conditions for pharmaceutical storage, laboratory samples, and biological growth cultures.
Production and Warehousing - Validate the shelf-life of fresh produce. Protect high-value raw materials and active ingredients to avoid damage and oxidation.
Animal Care and Enclosures - Monitor for stable, safe temperatures for livestock and exotic pets. Track conditions across fish tanks, reptile terrariums, amphibian vivariums, egg incubators, and neonate tanks.

How many readings does the NODE store?
The NODE range has internal memory to store up to 70,000 temperature readings.
How often can temperature be checked with NODE?
The default temperature check will be set to a maximum of 1 temperature measurement reading every 5 minutes with the Free Cloud tier. This is customisable up to recording a reading every 1 minute with paid Cloud subscriptions for businesses.
What happens if my internet goes down?
The NODE unit will continue logging and store the readings in its memory until it is next connected to WiFi ensuring continued monitoring.
How do NODE App Alerts Work?
Basic ETI Cloud subscription allows you to setup your trigger settings for high or low temperature limits. If the temperature on your NODE WiFi logger hits any of the thresholds a transmission will be forced through to ETI Cloud, triggering an alert to be sent to your ETI App.
Additional SMS and E-mail notifications can be set with subscription.
What is the temperature range and accuracy of this NODE model?
This NODE model has an internal temperature range of -25 to +50°C
and an external temperature range of -50 to +70°C
This NODE model has internal sensor accuracy of ±0.5°C from -25 to +50°C
External probe accuracy is dependent on probe selection for the NODE models with probe ports.
What are the NODE WiFi network compatibility requirements?
The NODEs require a 2.4GHz network frequency operating on 802.11 b/g/n wireless standards. They support WEP, WPA, and WPA2 security protocols.
Three further NODE models available
NODE WiFi Thermometer - One internal sensor for room temperature monitoring
NODE WiFi Thermometer with 1 Probe Port - One internal sensor plus one external probe ports for monitoring both room temperature and two devices or processes, such as a fridge and a freezer
NODE WiFi Temperature & Humidity Monitor - Measures temperature and humidity for moisture-sensitive environments
