Product Description

The CMP5000 is a relative humidity and temperature probe for Maturix® Concrete Humidity Monitoring. It is used together with the Gaia 220 transmitter and can be used for fresh and hardened concrete.

The CMP5000 probe is equipped with an Anti-Drift System, allowing prolonged exposure to high humidity levels without damaging the sensor.

Install the CMP5000, connect it to the Gaia 220 and the data is sent wirelessly to the cloud. The humidity and temperature readings are available in the web portal. The concrete drying process can be followed in real-time, and you can access the data from anywhere.

The Gaia 220 transmitter can be reused again and again. The CMP5000 probe can be either embedded into concrete or installed using a borehole method, making it reusable, especially if installed using the available liner.
