LD-200 Heated Diode Handheld Leak Detector – Refrigerant Gas Sniffer with Audible Alarm

Detect refrigerant leaks quickly and reliably with the LD-200 heated diode handheld leak detector. Designed for HVAC technicians, refrigeration repair professionals, and automotive AC specialists, this sensitive instrument identifies even tiny leaks of halogen‑based refrigerants (CFCs, HFCs, HCFCs) including R‑134a, R‑12, R‑22, R‑410A, and R‑404A.

The heated diode sensor delivers fast response and high sensitivity, with adjustable sensitivity levels to pinpoint the exact leak location. The audible alarm and visual LED indicator alert you as the probe approaches the source – the beep frequency increases as you get closer.

The flexible stainless steel gooseneck allows access to tight spaces behind compressors, coils, and pipe fittings. Low battery indicator and auto‑power‑off save energy.

Compact and lightweight, the LD‑200 is a practical, budget‑friendly tool for routine maintenance and emergency repairs.

Find leaks fast. Save refrigerants. Work confidently.
