Fieldpiece DR58 Refrigerant Leak Detector — Heated Diode, Ultra-Sensitive

Fieldpiece DR58 Refrigerant Leak Detector — Heated-Diode HVAC Sniffer

The Fieldpiece DR58 refrigerant leak detector is a pro-grade, ultra-sensitive heated-diode sniffer for halogenated refrigerants (CFCs, HCFCs, HFCs, HFOs and HC blends) — the gas leak detector HVAC technicians reach for to chase small refrigerant losses to their source. It finds the leak; it is not an atmosphere-safety monitor.

What the Fieldpiece DR58 detects (and what it doesn’t)

The DR58 detects halogenated refrigerants (CFCs, HCFCs, HFCs, HFOs and HC blends) — it does not detect combustible gases, CO or oxygen. For natural-gas or propane leaks use a combustible sniffer like the Klein ET120; for CO see the Carbon Monoxide Alarms & Detectors range. As a leak locator it shows where refrigerant escapes, not whether a space is safe — for occupied-space safety use a Portable Gas Detectors monitor. Heated-diode sensors are wear items; keep a replacement on hand.

Cross-shopping? This unit sits in our Gas Leak Detectors hub alongside Klein Tools ET120, Forensics Gas Leak Detector, TopTes PT-830S, TopTes PT520A. For other gas-detection form factors see Portable Gas Detectors, Personal & Wearable Gas Detectors, Fixed Gas Detection Systems, or browse the full Gas Detectors range.

How the Fieldpiece DR58 compares

The DR58 is the pro-grade pick among the refrigerant detectors we stock. The Elitech ILD-200 uses a long-life infrared sensor at a lower price; the TopTes RT-389 is a budget rechargeable option with selectable sensitivity.

• Choose the Fieldpiece DR58 for pro-grade, ultra-sensitive heated-diode refrigerant detection.
• Prefer a long-life infrared sensor at lower cost? See the Elitech ILD-200.
• On a budget? The TopTes RT-389 is a rechargeable entry option.

Frequently asked questions

What refrigerants does the Fieldpiece DR58 detect?

It detects halogenated refrigerants (CFCs, HCFCs, HFCs, HFOs and HC blends) — CFC, HCFC, HFC and HFO types. It does not detect combustible gases or CO.

What sensor does the DR58 use?

A heated-diode sensor, valued for high sensitivity to halogenated refrigerants. Heated-diode sensors are wear items and are replaced periodically.

How sensitive is the DR58?

It is an ultra-sensitive pro-grade detector designed to find small refrigerant losses; sweep slowly and watch the backlit LCD climb toward the leak.

How is it different from the Elitech ILD-200?

The DR58 uses a heated-diode sensor and is a premium Fieldpiece tool; the Elitech ILD-200 uses a long-life infrared sensor at a lower price.

Can it tell me if a space is safe to enter?

No — it locates refrigerant leaks only. For occupied-space safety use a Portable Gas Detectors monitor.

Does the DR58 detect natural gas or propane?

No — it is refrigerant-specific. For combustibles use the Klein ET120 or a TopTes combustible sniffer.

How do I pinpoint a refrigerant leak?

Move the probe slowly along joints, fittings and coils; the display and alarm intensify as you near the leak, then peak at the source.

Is the heated-diode sensor replaceable?

Yes — heated-diode sensors wear over time and are replaced as a consumable to keep sensitivity high. Budget for replacement sensors.

Is the DR58 good for automotive A/C?

Yes — it is widely used for automotive A/C diagnostics as well as HVAC/R service, thanks to its sensitivity and broad refrigerant coverage.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

Does it have a numeric leak-rate readout?

It shows leak intensity on a large backlit LCD to guide pinpointing; for certification you would confirm against your refrigerant-management procedure.

Why choose the DR58 over a budget detector?

Pro-grade sensitivity and Fieldpiece reliability for daily HVAC use; budget options like the TopTes RT-389 cost less but are less sensitive and durable.
