The Fieldpiece DR58 Heated Diode Refrigerant Leak Detector helps users quickly find leaks in the field with sensitivity better than 0.03 oz./yr (1g/a). The DR58 detects all HFC, CFC, HCFC, HFO, tracer gas, and blended refrigerants. Superior sensitivity at detecting R410A refrigerant is featured on the DR58.

The DR58's bright screen has an easy-to-read bar graph, numeric readings, and customizable dual alarms, so the user will always know exactly what they are seeing. A red LED flashes at the tip so the user can keep their eyes on the target. The large bars on the backlit LCD are easy to see in both bright sunlight or low light, and the numerical value provides an extra digit of resolution. In addition, users have full control with both an automatic (AZERO) and manual (MZERO) zero mode.

The large li-ion rechargeable battery provides over 18 hours of continuous operation and is convenient to charge via USB-C. Replaceable tips filter out water and dust while getting into tight spots. The DR58 is designed to handle tough jobsite conditions that most leak detectors cannot with an impact resistant IP54-certified body that fits easily in the user's hand.
