Fieldpiece DR58 Heated Diode Refrigerant Leak Detector

Since it’s a Fieldpiece, the 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.
