Employs mass spectrometer sensor technology with detection sensitivity ranging from 10^-7 to 10^-12 mbar·l/s. Features integrated roughing pump, turbomolecular pump, and ion source chamber. Interfaces via RS-232/485 serial communication, analog outputs 0-10V, and digital I/O for PLC integration. Touchscreen HMI provides local control and diagnostics. Accepts standard KF/CF vacuum flanges for test chamber connection. Common applications include semiconductor wafer processing equipment qualification, cryogenic vessel integrity verification, automotive fuel system testing, and pharmaceutical packaging validation. Operates on 100-240VAC single-phase power. ## Function Designed to detect and precisely locate hydrogen leaks using forming gas (5% hydrogen in nitrogen) as tracer, the equipment features high sensitivity to hydrogen concentrations while remaining tolerant to interfering gases. It supports semi-quantitative leak detection with audio-visual cues and an auto-ranging sensitivity mode for identifying leaks from very small sizes (~5 x 10^-7 mbar·l/s) up to occasional large leaks. The robust, user-friendly instrument enables rapid leak pinpointing without frequent calibration or adjustments and interfaces with various probes and accessories for tailored tracer gas filling and leak testing setups. ## Platform Dedicated hydrogen leak detection system employing thermal conductivity-based sensing for precise H2 gas identification in various industrial environments. Utilizes specialized detection chambers with high sensitivity for hydrogen molecules down to ppm levels. Compatible with pressure and vacuum systems including process piping, storage tanks, fuel cells, and semiconductor manufacturing equipment. Features analog/digital outputs for integration with control systems and data acquisition hardware. Operates effectively across temperature ranges from 5°C to 40°C with humidity tolerance up to 80% non-condensing. Requires standard power inputs and can interface with automated test systems via RS-232/485 communication protocols. ## Application Designed for sensitive detection of hydrogen leaks using tracer gas mixtures (5% hydrogen in nitrogen), this leak detector is suited for production and maintenance environments where precise pinpointing of leaks is required, including those that would allow leakage of liquids like water, fuel, or oils. Its robustness and tolerance to high gas concentrations enable reliable detection across a wide leak size range, facilitating rapid quality control, leak testing, and maintenance in vacuum systems, industrial facilities, and assembly line leak verification. The instrument supports integration with tracer gas filling and fixture control setups for automated or manual leak inspection workflows. ## Accessories Sampling probes (flexible, rigid, various lengths), H2/N2 calibration gas standard, gas regulator, inlet particulate filters, power cord (IEC C13). Interfaces: Sample inlet (barb/quick-connect, 4/6mm ID tubing), Power (IEC 60320 C14), Communication (DB9 RS-232), I/O (multi-pin D-sub for alarm, analog output, remote control). ## Interface RS-232C serial port for remote operation, standard 3-pin XLR connector for external sniffer probe, analog output (0-10V) via BNC connector for connection to external measurement devices, discrete I/O interface with 15-pin D-sub connector for integration with control systems, USB port for data logging and firmware updates, and a sniffer sampling probe inlet with quick-connect fitting. ## Images - - - - -
