Description : Connected electronic pressure gauge with 4-channel graphic touch display - TF-VRM4-SN
This connected electronic pressure gauge is revolutionising diagnostics and commissioning of refrigeration and air-conditioning systems thanks to its groundbreaking wireless features.
Touch. Read. Control.
Discover the VRM4-SN, the next-generation pressure gauge designed to optimise your workflow.
The VRM4-SN is an indispensable tool for any HVAC technician. Thanks to its ‘plug-and-play’ setup, all you need to do is plug it in to manage everything: diagnostics, charging and evacuation.
What truly sets the VRM4-SN apart is its user-centred design. The display is not just about aesthetics: it is designed to streamline your work.
Inspired by principles from aeronautics, it features a high-definition colour touchscreen and an enhanced interface to make these three key functions more intuitive, more visual and more precise: multi-gauge mode, leak test mode and evacuation mode with leak test.
Ease of use goes hand in hand with customisation. The VRM4-SN offers four themes, including ‘Day-Night’ mode for optimal visibility in direct sunlight, and further features are set to be introduced in future firmware updates.
It is not simply a measuring device. It is a measuring device that helps you do the job better.
Its intuitive design enables comprehensive and accurate diagnostics at a single glance
The TF-VRM4-SN pressure gauge connects to the HiValue mobile app, available in French, German, English, Spanish and Portuguese on the App Store and
Google Play.
It connects effortlessly to temperature probes and connected pressure sensors to provide comprehensive remote data, displayed directly on the TF-VRM4-SN’s screen.
The robust aluminium body and 1/4-turn ball valve ensure long-lasting durability, whilst the concealed folding hook enhances portability. With Class 0.4 accuracy and a clear digital display, it provides precise readings.
Designed to withstand the challenges of the field, its shock-resistant, rubber-coated construction ensures reliable long-term performance.
The VRM4-SN will help HVAC-R professionals improve their efficiency and reduce costs.
The big advantage of the electronic pressure gauge:
With a maximum pressure rating of 75 bar on both the LP and HP sides, there is no risk of the LP pressure gauge breaking ✅.
Practical and reliable: Quarter-turn buttons
Accurate: Reading class 0.4
Supplied in a case with a USB-C charging cable
