The Fieldpiece DR58 Heated Diode Refrigerant Leak Detector is full of the features you need. Multiple indicators and sensitivity 20x higher than soap bubbles make it easy to track down even the smallest leaks in various environments. A red LED flashes at the tip so you can keep your eyes on the target. The large bars on the backlit LCD are easy to see in bright sunlight or low light, and the numerical value provides an extra digit of resolution. Unlike conventional leak detectors, you 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. All wrapped up in a ruggedized IP54 housing, it’s built for the field.

Clearly see even the smallest leak.
Sniffing leaks at less than 0.03 oz/yr (1g/a), the Fieldpiece DR58 detects all HFC, CFC, HCFC, HFO, and blended refrigerants with superior sensitivity at detecting R410A refrigerant. On the DR58’s new, bright backlit LCD screen you’ll see easy-to-read bar graphs, numeric readings, and customizable dual alarms. No more guessing about what’s leaking. Also, it can both automatically and manually zero refrigerant gas concentrations giving you total control.

Detects faster. Lasts longer.
The DR58 boasts an 18-hour battery life that’ll last longer than you will on the job site. Yes, it’s built to perform. Soap bubble solutions can take several minutes to form visible bubbles and messy UV dyes can take several hours to travel through a running system.

Where is the sensor located on the DR58?

To install or replace the sensor, make sure the unit is turned off. Then, unscrew the snoot on the DR58, and if replacing gently pull the sensor from the base.

What is the difference between the DR58 and DR82?

The DR58 uses a heated diode sensor. The DR82 uses an infrared (IR) sensor.
