SENSYX SFD201 Rechargeable HVAC Leak Detector | Halogen Freon Sniffer

Overview

The SENSYX SFD201 Rechargeable Leak Detector is designed for professionals who service HVAC systems and automotive air conditioning. Its compact, handheld form hides a capable sensor array that helps you locate leaks quickly, across a broad range of refrigerants and related gases. By blending portability with reliable detection, this tool aims to streamline diagnostics on busy job sites.

Key capabilities

Rechargeable lithium battery with USB-C charging enables cordless operation, while a Japan-made heat dioxide semiconductor sensor delivers high sensitivity. You can adjust sensitivity with High and Low settings to suit noisy shops or tight spaces. The detector covers a broad mix of halogen refrigerants and select HC/combustible gases, making it versatile for various HVAC and automotive tasks. A large color LCD screen provides clear readings, and the device adheres to UL1484 safety standards. US-based customer service and technical support are available to assist with setup and use.

Practical use scenarios

In fieldwork, timing matters. The SFD201’s clear visual readouts help technicians quickly identify leak locations, reducing guesswork and downtime. For automotive technicians, it supports AC service with reliable performance across common refrigerants like R134a and related blends. In industrial settings, the wide detection range allows screening for both refrigerants and select combustible gases, enabling a single, flexible tool for multiple applications.

Note: Always follow safety guidelines for refrigerants, including proper ventilation and personal protective equipment. This detector is intended to aid detection and should complement, not replace, safety training and standard procedures.
