Professional Leak Detection for Modern HVAC & Refrigeration Systems
The H2Leak DXR-240 is a high-performance, portable leak detector engineered for HVAC technicians, refrigeration contractors, and service professionals who demand accuracy, speed, and versatility.
Designed to detect both refrigerant gases (HFC, HFO, HC) and hydrogen/nitrogen (H₂/N₂) tracer gas, the DXR-240 gives you a dual-method leak detection solution—perfect for locating even the smallest leaks in commercial and residential systems.
Whether you’re servicing supermarket refrigeration racks, VRF systems, chillers, or residential AC units, the DXR-240 delivers reliable results every time.
Ultra-High Sensitivity for Micro-Leaks
- Sensitivity down to ~1 g/year refrigerant equivalent
- Detects extremely small leaks that standard sniffers may miss
- Perfect for EPA compliance, GreenChill programs, and leak reduction initiatives
Increase Service Revenue with Advanced Leak Detection
Adding the DXR-240 to your service offering allows you to:
- Detect leaks faster and more accurately
- Reduce callback visits
- Offer premium leak detection services
- Increase billable service revenue
- Differentiate from competitors
For plumbing and HVAC contractors, hydrogen-based leak detection is a high-margin service upgrade that delivers immediate ROI.
Designed for HVAC & Refrigeration Professionals
The DXR-240 is purpose-built for:
Commercial Refrigeration
- Supermarkets & grocery stores
- Rack refrigeration systems
- Walk-in coolers & freezers
HVAC Systems

- Residential & commercial AC systems
Leak Detection with Tracer Gas
- Ideal for hydrogen tracer gas leak detection
- Perfect for locating leaks that traditional methods miss
🔍 Why Use the DXR-240 for Hydrogen or Refrigerant Tracer Detection?
Hydrogen tracer gas (typically 95% nitrogen / 5% hydrogen) is one of the most effective leak detection methods available:
- Hydrogen is an Ultra-small molecules that escape even microscopic leaks.
- Hydrogen is Non-toxic and safe in low concentrations
- Faster and more accurate than soap bubbles or nitrogen pressure tests
- Refrigerant capability of the DXR-240 means tech can detect for either refrigerant or H2 with one high level detector
This makes the DXR-240 an essential tool for technicians working on tightness testing, commissioning, and difficult leak scenarios.
