Fieldpiece DR58 vs Elitech ILD-200: Refrigerant Leak Detector Showdown
Fieldpiece DR58 vs Elitech ILD-200 — which refrigerant detector?
Short answer: Choose the Fieldpiece DR58 for pro-grade heated-diode sensitivity; choose the Elitech ILD-200 for a long-life infrared sensor and lower lifetime cost.
Both find halogenated refrigerant leaks, but they use different sensors with different trade-offs. Both are in Gas Leak Detectors.

Heated diode vs infrared
Heated-diode sensors (DR58) offer very high peak sensitivity but wear out and are replaced as consumables. Infrared sensors (ILD-200) are slightly less sensitive but last roughly a decade and resist drift, which lowers running cost for shops doing frequent leak checks. Both are refrigerant-specific; for combustible-gas leaks use the Klein ET120.

Frequently asked questions
What sensor does each use?
The Fieldpiece DR58 uses a heated diode; the Elitech ILD-200 uses a long-life infrared (NDIR) sensor.
Which is more sensitive?
The DR58 has higher peak sensitivity; the ILD-200 trades a little sensitivity for sensor longevity.
Which has lower running cost?
The ILD-200 — its infrared sensor lasts about 10 years, avoiding frequent sensor replacement.
Which refrigerants do they detect?
Both detect halogenated refrigerants (CFC, HCFC, HFC); the DR58 also covers HFO blends.
Which is cheaper upfront?
The Elitech ILD-200 (~$191) versus the Fieldpiece DR58 (~$375).
Do they detect natural gas or propane?
No — for combustibles use the Klein ET120.
Can they tell me if a space is safe?
No — they locate leaks. For atmosphere safety use a gas monitor.
Which for a busy HVAC shop?
The ILD-200 for low upkeep, or the DR58 if you need maximum sensitivity on tiny leaks.
Do heated-diode sensors need replacing?
Yes — they are consumables; budget for replacements with the DR58.
Are they good for automotive A/C?
Yes — both work for automotive A/C as well as HVAC/R service.
