Device-mounted hydrogen leak detector | HDZ-0201

● What is a hydrogen leak detector? It can measure leaks in small areas that could not be detected in air leak tests and can also identify the leak locations. It is a detector that uses a mixture of 5% hydrogen and 95% nitrogen (non-flammable gas: ISO10156:2017) as the tracer gas. ● What is a helium leak test system? It is a leak test system suitable for high-precision or high-pressure leak inspections. The helium leak test system uses helium gas as the detection gas (tracer gas) and detects the helium that has leaked out. It is the leak test method among Fukuda's leak testers that can detect the smallest leaks.

The HDZ-0201 is a hydrogen leak detector designed for installation in equipment. It is used to measure the overall leakage from the entire inspected item (workpiece). - The atmospheric pressure chamber method involves covering the workpiece with a chamber, filling the inside of the workpiece with tracer gas, allowing the leaked gas to accumulate in the chamber, stirring the leaked gas, and forcing circulation to measure the gas concentration with a hydrogen detector. - The vacuum chamber method allows for high-sensitivity measurements by evacuating the chamber and then introducing atmospheric air into the chamber, directing the gas to the hydrogen detector. There are two methods available. It features a compact and lightweight design that is easy to integrate into equipment. Additionally, its concentration resolution capability is ultra-high sensitivity up to 0.1 ppm (depending on set conditions and environmental conditions). Detection principle: Semiconductor type Detection sensitivity: Equivalent to 1×10⁻⁶ Pa·m³/s (depending on inspection conditions and measurement environment) Usage: Equipment-integrated type (dedicated for installation in equipment) Resolution: 0.1 ppm Power supply voltage: DC 24 V External dimensions: W 93 × D 91 × H 97 mm
