In the HVACR world, no job is complete until you’re sure the system is leak-free. Whether you’re chasing down leaks in a pre-charged line set, servicing a rooftop unit, or working on a complex refrigeration system, your leak detector needs to be fast, accurate, and built for real-world conditions. That’s exactly what the new Fieldpiece DRX3 All-in-One Leak Detector delivers.
The DRX3 simplifies leak detection like never before. It combines heated diode technology, wide refrigerant and combustible gas compatibility, and rugged portability into one powerful tool, helping HVACR pros save time, travel lighter, and stay safe—no matter what kind of refrigerant or gas they’re working with.
Let’s take a closer look at why DRX3 is a must-have for service calls, installs, and everything in between.
Built for Today’s Refrigerants — And Tomorrow’s
With refrigerant regulations evolving and new blends entering the market, technicians face a growing list of refrigerants and gases they need to detect. The DRX3 is built to handle the full range:
This means one sensor handles virtually every leak scenario you encounter, there’s no need to swap detectors depending on the job.
Whether you’re working with common A3, A2L, A1 refrigerants or heating fuels, the DRX3’s heated diode sensor delivers fast, reliable detection across the board. The sensor is easy to replace in the field after its typical 300-hour life, keeping your downtime to a minimum.
Speed + Accuracy = Less Time on the Job
The DRX3 was designed with real-world HVACR work in mind: tight spaces, hard-to-reach joints, and time-sensitive calls. That’s where its advanced feedback system shines. The DRX3 gives you multiple ways to spot leaks quickly and confidently:
With high, medium, and low sensitivity settings plus both auto and manual zeroing, you can fine-tune the detector depending on your environment—whether you’re in a drafty mechanical room or a tight equipment closet.
One Tool That Travels Light
Every technician knows: lighter is better. The DRX3 was built to consolidate your toolbag. Instead of carrying multiple detectors for different refrigerants or gases, one DRX3 does it all. Its rugged, compact design holds up to daily wear and tear.
The flexible wand helps you reach tough spots around evaporator coils, compressor cabinets, and complex line sets. Meanwhile, field-replaceable, long-life batteries ensure the DRX3 stays powered up when you need it most—without constant recharging or replacing.
Safety Compliance
Working with A2L and A3 refrigerants introduces new safety requirements due to flammability risks. The DRX3 is compatible for use in hazardous environments, complying with the requirements of:
These safety standards give you confidence that your leak detector has been tested for use around mildly flammable and flammable refrigerants and gases, meeting industry safety standards while helping you stay compliant.
Connected with Job Link® for Easy Reporting
Leak detection doesn’t end when you find the problem—you still need to document it. That’s where the DRX3’s Job Link® System App compatibility takes things to the next level.
By pairing your DRX3 with the Job Link® app, you can:
This connected workflow helps reduce callbacks, streamline service calls, and provide a professional level of transparency to your customers.
The Bottom Line
The DRX3 is more than just another leak detector, it’s your all-in-one solution for handling today’s wide variety of refrigerants and gases; while delivering the speed, safety, and accuracy you expect from Fieldpiece.
With its heated diode sensor, multiple feedback indicators, hazardous location compliance, and Job Link® connectivity, the DRX3 helps HVACR professionals tackle service calls and installs with confidence. Whether you’re upgrading your current tool or building your ultimate leak detection kit, the DRX3 belongs in your bag.
