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.![[ Image ] A low-cost leak test using hydrogen](./file/532/h_feature_whats_img01.jpg)
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

Line up
-
Desktop Hydrogen Leak Detector YHLD-100A desktop hydrogen leak detector that detects the leak without fail and identifies the leak location just with one unit. With its wide dynamic range, concentrations from 0.5 ppm to 13,000 ppm are measured. Measurement is performed quickly, safely, and widely. -
Cordless Hydrogen Leak Detector YHLD-300A portable, handy, and small hydrogen leak detector. This detector is a cordless version inheriting as-is the function of YHLD-100 that detects concentrations in the range 0.5 ppm to 13,000 ppm. Any location can be detected freely. -
Hydrogen trace gas generator YMHN-50This equipment can generate a hydrogen-nitrogen mixed gas just by supplying purified water. Capable of generating trace gases that comply with international standards in a safe and affordable manner.
