Handheld Leak Detectors

The same instrument philosophy as our RV detectors — a FIGARO sensor you can trust and a display that shows you what it found — in a service tool that fits in one hand.

Two models. One difference.

Both share the same FIGARO heated semiconductor sensor (Japan), color LCD leak-level display, adjustable sensitivity, and USB-C rechargeable battery. The SFD201 adds a second detection mode for combustible gases.

SFD200SFD201
Halogen refrigerants (R134a, R410a, R32, R22, R1234yf, and more)
Combustible gases (methane, ethane, propane, isobutane)
FIGARO heated semiconductor sensor (Japan)
Color LCD leak-level display
USB-C rechargeable lithium battery
Tested to UL 1484

Which one do I need?

  • HVAC and automotive A/C service on standard refrigerants — the SFD200 covers every halogen refrigerant you'll meet.
  • Working with hydrocarbon refrigerants (R290, R600a) or around fuel-gas lines — choose the SFD201.
  • Not sure? The SFD201 does everything the SFD200 does. If your work might ever touch propane-based refrigerants or gas lines, it's the safer pick.

Where they're used

  • HVAC service — residential and light-commercial split systems, heat pumps, mini-splits
  • Automotive A/C — R134a and R1234yf systems, fittings, compressors, evaporators
  • Refrigeration — home refrigerators and freezers (R600a systems: use SFD201), commercial coolers
  • RV owners — your rig's rooftop A/C and refrigerator can leak too; the same tool covers both
