CMDDA1 Kit

The testo CMDDA1 Kit is a comprehensive and essential toolset for qualified gas engineers in the UK who are required to investigate reports of fumes, smells, or carbon monoxide (CO) alarm activations in domestic properties. Designed to meet the requirements of the CMDDA1 (Carbon Monoxide/Dioxide Dwelling Atmosphere and Appliance Testing) qualification, this kit provides a complete solution for in-depth, professional gas safety investigations.

This kit is specifically configured to meet the requirements of the CMDDA1 qualification, ensuring you have all the necessary tools to perform a compliant and professional fume investigation.
The testo CMDDA1 Kit offers a seamless digital workflow by integrating the included probes with the testo Smart App via Bluetooth. This connectivity allows you to view real-time data on your mobile device, perform a detailed diagnosis, and even remotely control the instruments.
