Made in USA
No software to install. No cloud accounts to create. Connect up to three thermocouples, power on, monitor.
Plug the three included K-Type probes into the on-board connectors. Built-in hot and cold junctions deliver accurate readings, and each connector also accepts a high-temperature probe rated up to 2000°F — or other thermocouple types and ranges — when a process runs hotter.
Mount the enclosure on or near your equipment, optional magnetic hardware makes it tool-free. Run on the D-cell with Supercap or add the external-power option for permanent installations.
900MHz self-forming wireless mesh network. Up to 2-mile line-of-sight range with the on-board antenna.
Browser dashboards, per-channel threshold alerts, and CSV export through the Atrium gateway. Compare all three zones on one timeline and catch excursions before they become failures.
The Atrium Gateway isn’t just a data receiver. It’s a complete industrial IoT platform with dashboards, alerts, reporting, and built-in apps. Point your thermocouple sensors at it, open your browser, and go, your data stays on your network.
Drag-and-drop widgets let you build custom monitoring views for any audience, operators on the floor, maintenance managers, or front-office leadership. Every dashboard auto-refreshes and supports fullscreen mode for wall-mounted displays.
In Atrium, Triggers are threshold conditions on a single thermocouple channel, they fire when a reading crosses the line. Actions link one or more triggers to responses like email or relay control, and run when every trigger is met. You build both in the browser, no code required.

Atrium works as a fully self-contained system, but when you need to integrate, Node-RED is built in and ready. Push data to cloud platforms, databases, or custom APIs, all configured through a visual flow editor.
Three-channel temperature monitoring that runs locally. No cloud dependency. No software license.
Three on-board K-Type connectors read three independent temperature points from a single node, each with built-in hot and cold junctions for accurate readings.
Ships with three K-Type thermocouple probes on a 1 m, 24 AWG cable, rated for readings up to 500°F. Each connector also accepts a high-temperature probe rated up to 2000°F, or other thermocouple types and ranges, when a process runs hotter.
Beyond the standard K-Type, each connector accepts other thermocouple types on request, so you can match the probe to the process. Types J, T, E, and N cover general-purpose, cryogenic, and high-sensitivity work; noble-metal types S, R, and B handle precision measurement up to 1600–1700°C. Swap probes without changing the sensor.
A D-cell with Supercap delivers up to 5 years of battery life. An external-power option is also available for permanent installations.
An IP65-rated enclosure with wall-mount and magnet-mount options stands up to harsh industrial environments, while the on-board antenna keeps installs simple. The IP65 rating covers the main enclosure only, not the thermocouple probe.
Update firmware wirelessly across your fleet over the wireless mesh network. No climbing ladders, no removing sensors from service.

Answers to the most common questions about 3-channel wireless thermocouple temperature monitoring.
It is a battery-powered industrial sensor from NCD that reads three K-Type thermocouples at once and transmits all three channels wirelessly up to 2 miles line-of-sight. It ships with three K-Type probes rated for measurement up to 260°C (500°F); each channel also accepts a high-temperature probe rated up to 1090°C (2000°F), with other thermocouple types and ranges available on request. It runs on a D-cell with Supercap good for up to 5 years and carries no monthly fees or subscriptions.
Three. The sensor has three independent K-Type thermocouple channels, so a single node can read three separate temperature points, three oven zones, both sides of a heat exchanger plus ambient, or top/middle/bottom of a tank, instead of installing three separate sensors.
The sensor includes three K-Type thermocouple probes with a 1 m, 24 AWG cable, rated for measurement up to 260°C (500°F). Built-in hot and cold junctions keep readings accurate. Each connector also accepts a high-temperature K-Type probe rated up to 1090°C (2000°F), or other thermocouple types and ranges, if a process runs hotter.
Yes. The sensor has three K-Type connectors, so you can connect your own thermocouples on any channel, including a high-temperature probe rated up to 2000°F or other thermocouple types and ranges for hotter processes. The three included K-Type probes get you reading right out of the box.
The sensor reaches up to 2 miles line-of-sight with its on-board antenna, over 900MHz long-range wireless mesh networking. Because it forms a self-healing mesh, a single Atrium gateway can collect readings from many sensors across large or multi-building facilities.
The sensor runs on a D-cell with Supercap, and delivers up to 5 years of battery life. An external-power option is also available for permanent installations.
No. The 3-Channel Wireless Thermocouple Sensor has no monthly fees and no proprietary lock-in. You own your data and can keep it on your own network or forward it to AWS, Azure, or any MQTT broker through the Atrium gateway, there are no recurring software costs.
Yes. Readings from all three channels flow through the Atrium gateway, which supports AWS, Azure, MQTT, Modbus, Node-RED, and a REST API. Its open communication protocol makes software integration straightforward, so you can route data into existing CMMS or analytics platforms without vendor lock-in.
The enclosure is wall-mountable, and optional magnetic mounting hardware lets you attach it to metal equipment without tools. The three thermocouple probes are what reach into the temperature points you want to monitor, while the node stays in an accessible spot for wireless transmission.
The 3-Channel Industrial IoT Wireless Thermocouple Temperature Sensor is made in the USA and is RoHS compliant. It is built and supported by NCD, a manufacturer trusted by more than 7,000 customers worldwide for industrial wireless sensing.
One sensor, three channels, full ownership. Industrial-grade temperature monitoring that pays for itself.
