YHLD-300
PRODUCT DESCRIPTION
- Yamaha's proprietary MEMS hydrogen sensor installed
- Measured value quickly displayed on the display at hand by the one-touch peak hold function
- Return after measurement also made quick through high-speed response in one second or less
- Power supply from dry batteries or from outside possible
A portable and handy, small lightweight type, detecting any location freely
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. You can perform detection freely while checking with the display at hand. The energy saving function using the acceleration sensor is provided.
features
- Detected concentration : 0.5~13,000ppm
- Detection method : Sniffer method
