Fieldpiece DR58 Heated Diode Refrigerant Leak Detector
The Fieldpiece DR58 is a professional, portable heated diode refrigerant leak detector with a backlit LCD display designed to identify even very small refrigerant leaks with high sensitivity. It is ideal for HVAC/R technicians working on air conditioning and refrigeration systems.
Description
The Fieldpiece DR58 is an advanced diagnostic tool for locating refrigerant leaks in HVAC/R circuits. Its heated diode sensor delivers excellent sensitivity (better than 0.03 oz/year — approximately 1 g/year) and can detect all major refrigerants including HFC, HCFC, CFC, HFO and blends. The detector is also compatible with A2L refrigerants.
The bright backlit LCD display provides easy-to-read bar graphs and numeric readings, while dual audible and visual alarms help guide the operator to the source of the leak. A built-in LED illuminated tip assists in finding leaks in dark or noisy environments.
The unit is rugged and certified with an IP54-rated body that resists impact and field conditions. USB-rechargeable lithium-ion battery provides up to 18 hours of runtime, and both automatic and manual zeroing functions allow full control during leak detection.

FAQ
The HFC phase-down involves a progressive reduction in the quantities of these high-global-warming-potential refrigerants placed on the market, through an increasingly restrictive quota system. The goal is to facilitate the transition to lower-GWP refrigerants and reduce the climate impact of the HVAC&R sector.
Adapting early to the phase-down allows companies to avoid the critical issues associated with reducing HFC quotas, such as higher prices and reduced market availability. It also allows for timely investment in more efficient and sustainable technologies, improving competitiveness in the medium term.
The reduction of HFCs accelerates the development and deployment of solutions based on low-environmental impact refrigerants, such as natural fluids or new low-GWP blends. This process stimulates technological innovation and new design models for more efficient and sustainable refrigeration systems.
