Hydrogen Leak Detector Hydrogen Leak Detection System

Yamaha Fine Tech's proprietary MEMS hydrogen sensor equipped, and a wide range of concentrations, from low to high concentrations, detectable just with one unit.
A high resolution hydrogen leak detector that can detect low to high concentrations in the range from 0.5 ppm to 13,000 ppm with a single unit.
Quick measurement is realized by high-speed response and real measurement. A desktop type and a handy type are available.

Features of Hydrogen Leak Detector

Yamaha's proprietary MEMS hydrogen sensor adopted.

High resolution detection is possible with Yamaha's proprietary MEMS sensor. Low (0.5 ppm) to high (13,000 ppm) concentrations are supported.

Startup and return each in one second or less realized

High throughput inspection realizes return after measurement quickly, making it possible to move to the next detection quickly.

Danger detected quickly to generate a warning

When the hydrogen concentration exceeds 13,000 ppm (=1.3%), a "DANGER" message is displayed, and a warning is generated to stop the measurement process.

Real measurement

Even in an atmosphere with the same hydrogen concentration, as far as hydrogen is present, the detected value is displayed. At high hydrogen concentrations, neither linearity degradation nor output saturation occurs.

What is Hydrogen Leak Detector?

A low-cost leak test using hydrogen

The hydrogen leak detector is a leak testing device for identifying the leak location by injecting hydrogen into the workpiece and holding the sensor to the workpiece. Yamaha Fine Tech. introduces the sniffer method.

Advantages of using hydrogen

  • A leak test realized safety and at low cost because hydrogen is cheaper and safer than helium
  • Safe when using a gas mixture of 5% H2 and 95% N2 because it is inflammable
  • Generation possible by using a hydrogen generating unit
  • Cost reduction possible by properly using helium and hydrogen according to the workpiece because the hydrogen's detectable leak rate is a value between the value for helium and the value for air
