Helium Leak Detector SFJ-231

The Wayeal SFJ-231 is a mobile helium mass spectrometer leak detector for high-sensitivity vacuum and sniffer testing, with fast response, automatic helium background clearing, touch-screen operation, and production-ready communication interfaces.

Vacuum mode: 5.0×10⁻¹³ Pa·m³/s
Sniffer mode: 5.0×10⁻⁹ Pa·m³/s
Response / startup: <1 s / ≤2 min
Integration: I/O, RS232/485, MES, USB

Product Overview

SFJ-231 is designed for manufacturers and quality teams that need a movable helium leak detector for both vacuum-mode and sniffer-mode inspection. It combines a 16 m³/h backing pump, high helium pumping speed, a 7-inch touch screen, and flexible data interfaces for production, maintenance, and laboratory workflows.
