Desktop Hydrogen Leak Detector YHLD-100

Desktop Hydrogen Leak Detector
[ Image ] Desktop Hydrogen Leak Detector YHLD-100

Leak detected without fail and the leak location identified just with one unit

With its wide dynamic range, concentrations of 0.5 ppm to 13,000 ppm are measured just with one unit. For a concentration of 13,000 ppm or more, a warning is generated to stop the measurement process. The response speed is 0.7 seconds or less. Measurement is performed quickly, safely, and widely.
  • Yamaha's proprietary MEMS hydrogen sensor installed

  • With a large color LCD touch panel installed and through interactive mode selection and setting functionality, easy operation realized

  • Return after measurement also made quick through high-speed response in one second or less

  • At high hydrogen concentrations, no occurrence of linearity degradation or output saturation. Even at 2,000 ppm or more, an output made without saturation.
  • With the inline sensor head, inline automatic inspection supported
