A Leading Innovator in State-of-the-Art Measuring Technology
A Leading Innovator in State-of-the-Art Measuring Technology
Enables technicians to control their daily servicing and maintenance work on refrigeration, A/C systems, and heat pumps entirely from their smartphone/tablet. Save time with fast and easy measurements, clearly presented results, and digital documentation, plus identify temperature changes and measure vacuum with the included probes.
Enables technicians to control their daily servicing and maintenance work on refrigeration, A/C systems, and heat pumps entirely from their smartphone/tablet. Save time with fast and easy measurements, clearly presented results, and digital documentation, plus identify temperature changes and measure vacuum with the included probes.
Ready for all your jobs today and in the future, this fully digital manifold enables you to control your daily servicing and maintenance work on refrigeration, air conditioning systems, and heat pumps entirely via the Smart App and smartphone or tablet. Equipped with a two-way valve block, deals with measurements fast and conveniently, and thanks to the digital documentation, saves considerable time. Additionally, the compact instrument connects automatically via the Smart App to our Bluetooth® probes for temperature, pressure, and humidity. With nothing more in your hand than your smartphone, you are standing relaxed to one side, or up to 500' away.
Wireless measurement, uncomplicated documentation – with Bluetooth® 5.0, Smart App and free DataControl PC software.
Compact, handy and rugged: The rugged housing with its sunken display handles its job reliably even under extreme conditions.
The Smart App and intuitive user guidance make measurements faster and easier than ever before.

Welcome to the digital age of measurement technology. With the Smart App, you turn your smartphone into a mobile, multi-functional command center for all applications involving refrigeration, air conditioning, and heating systems. Together with the Bluetooth-enabled measuring instruments and Smart probes, this optimally equips you for the future. And everything which comes after it.
All applications of the digital manifolds on your smartphone. With the Smart App, you can evaluate results even faster. Additionally, it helps you to avoid measurement errors, as stored measurement programs guide you step-by-step through the configuration and measurements. With the integrated documentation functions, reports can be created on-site, and digital measurement protocols, including photos, can be sent as PDF or CSV files directly by email. You can also set up customer data and measurement sites at the touch of a button, and synchronization with the optional DataControl PC software is done wirelessly through Wi-Fi.
From the test site via the PC, to the finished job: With the DataControl software, measurement results and customer profiles can be managed easily and quickly – and the documentation is dealt with almost by itself.
