Fieldpiece DRX3 offre

The lightweight DRX3 helps you locate system leaks quickly with multiple visual and audio feedback indicators that change with leak intensity and is designed for performance and safety, complying with ATEX Zone 2 and Class I, division 2 hazardous location requirements.

Caractéristiques

• Refrigerant families: HC, HFC, HCFC, CFC, HFO, blends, plus H₂/N₂ tracer gas (listed as 5% H₂ / 95% N₂ on the product specs)
• Combustible/heating gases: Natural gas, propane, butane, methane
• Safety class coverage for refrigerants: intended for A1, A2L, and A3 refrigerants
• Auto and manual zero modes
• High, medium and low sensitivity settings
• Flashing red LED at the probe tip (blink rate increases with concentration)
• Audible alarm changes with leak intensity
• Backlit LCD shows bar graph and numeric “relative leak size” from 0–99 (relative units, not a calibrated ppm reading)
• Single heated diode sensor is field-replaceable and has a typical life of about 300 hours (the tool tracks usage with a sensor-hours counter)
• Long-life, field-replaceable batteries
• Job Link^® System App connected
