A Leading Innovator in State-of-the-Art Measuring Technology
A Leading Innovator in State-of-the-Art Measuring Technology
Features a two-way valve block, this rugged manifold enables you to carry out measurements on refrigeration, air conditioning systems, and heat pumps quickly and easily. Additionally, the large display shows all the results at a glance, along with a fast and easy pressure value display in an analog look.
Features a two-way valve block, this rugged manifold enables you to carry out measurements on refrigeration, air conditioning systems, and heat pumps quickly and easily. Additionally, the large display shows all the results at a glance, along with a fast and easy pressure value display in an analog look.
Make measurements on refrigeration, air conditioning systems, and heat pumps faster and easier than ever before. Features a large display to show all measurement data at a glance and simplifies the results. Measurement menus guide you step by step through the measurement and allow automatic determination of parameters such as superheat, pressure-drop test, tightness test, or evacuation.
Optional Bluetooth® probes for temperature, pressure, and humidity can be connected wirelessly to the manifold with the Smart App, providing even more flexibility, plus the app will always select the proper refrigerant. Thanks to its proven quality and durability, you can rely on maximum precision under any conditions, from the first to the last job.
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.
Extra-large graphic displays, 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.
