- Monitor directly inside the in-place structure for better insights into the curing behaviour
Gaia 200 &
Type K Thermocouple
Gaia 200 combines modern wireless technology with an industry-standard probe for the lowest cost-per-monitoring in real-time. Connect the transmitter to the thermocouple and embed the cable tip in the structure. The device starts measuring and transmitting continuously. The data is sent wirelessly to the cloud using Sigfox antennas or gateways.

Plug & play solution
Connect the wireless transmitter with a type K temperature probe. When a probe is connected, the transmitter automatically starts measuring and sending data to the cloud.
Flexible & versatile use
The thermocouple convinces with its high resistance and durability combined with flexible positioning and use.
Accurate & cost-efficient probe
The industry-standard thermocouple measures the temperature accurately with a low cost per monitoring. The probe is widely available and a cost-efficient solution for accurate measurements.
Check status easily
The LED indicator shows the transmission status and its battery lifetime for easy interaction.
Access from anywhere with wireless data communication
The data is sent wirelessly from the Gaia 200 transmitter to the cloud using Sigfox. It is the world’s leading IoT network, and data is sent through antennas or gateways and can be accessed in the web portal from anywhere.
Rugged design with replaceable batteries
The Gaia 200 is weather-resistant, with multiple mounting slots for easy installation. The batteries can be exchanged easily for extended use.

What is the Gaia 200?
The Gaia 200 is an electronic device that records temperature and wirelessly sends it to the cloud. The temperature is measured using type K thermocouples and the readings can be viewed online in one of our web portals, either Maturix In-situ or Maturix Precast.
How is the data transferred to the cloud?
The data is sent using Sigfox. Sigfox is a wireless network designed to connect smart devices to the cloud. It benefits from longer range than Bluetooth and WiFi, and you can set up a Sigfox Gateway at your job site to create coverage – even at remote locations.
Do I need to be at the job site to access the data?
No – and that is the smart thing! You can access the temperature readings from your computer or smartphone at any time, anywhere. Once you have installed the equipment, you can follow the temperature and strength development online in real-time.
How is the installation done?
Installation is quick and simple. Secure the thermocouple to the rebar, connect it to the Gaia 200, and place the transmitter at a secure location. When a thermocouple is connected, the Gaia 200 transmits data every 15 minutes automatically.
What is embedded into the concrete?
It is only the inexpensive thermocouple that is embedded into the concrete. The Gaia 200 is mounted next to the cast and can be reused for multiple monitorings. This not only gives great flexibility but also keeps the costs per monitoring down.
What is the battery lifetime?
The battery lifetime depends on the usage and the conditions. When the thermocouple is inserted 24/7, the battery lifetime is up to 8 months. We guarantee 20.000 measurements or 8 months operation (whichever comes first).
How many sensors do I need?
The Gaia 200 is an electronic device that records temperature and wirelessly sends it to the cloud. The temperature is measured using type K thermocouples and the readings can be viewed online in one of our web portals.
What is the price?
We are happy to talk about your project and needs. Contact us or one of our distributors to receive a tailored offer.
Why should I choose Maturix?
