NODE, WiFi Thermometer with Internal and 1 External Probe
Smart readings monitoring for cold storage made simple
Connect your device directly to your WiFi network to safely save data to the cloud. Log into your account from anywhere to track readings, view reports, and maintain a secure digital paper trail for HACCP or MHRA audits.
This model features one internal temperature sensor, and one probe port to attach a probe of your choice. The Pro-Series ambient suction cup probe is included with this model.
For food simulation, the Pro-Series glass simulant buffered probe with glass beads is sold separately. This mimics the internal temperature of stored goods instead of reading the ambient temperature of the fridge to prevent false alarms when fridge doors are opened briefly. NODE models are supplied with a UKAS calibration certificate for auditing confidence.
Setup via a web browser is quick and easy. You can customise your device name, reading frequency, and high/low temperature limits for each probe. A built-in battery ensures seamless recording even during a mains power cut.
Professional users can upgrade to a Cloud Subscription for advanced tools, including instant app alerts if temperatures drift outside your safe range. Whether managing perishable food or sensitive pharmaceuticals, this smart logger takes the effort out of daily refrigeration tracking and allows you to take quick action before valuable stock is lost.
The 1-port NODE is designed for
Fridges/freezers - Monitor produce active and raw materials or HACCP compliance, specialised refrigeration and industrial refrigeration processes
Laboratories and Medical - Maintain controlled conditions for the sample storage, pharmaceuticals storage or or growth culture.
Production and storage - From cosmetics and fragrance to chilled dairy and produce for shelf-life validation. For raw material & active ingredient preservation to avoid oxidation
Animal environments - Ensure a stable temperatures for fishtanks, 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
What are the NODE WiFi network compatibility requirements?
