Easy and convenient dissolved hydrogen meter.
The M687MD-XF allows you to easily check the concentration (ppm) of the popular hydrogen water. Instead of the expensive membrane polarographic method, it measures the hydrogen concentration of nearly neutral aqueous solutions using a cost-effective reduction potential method.
Portable hydrogen concentration meter with built-in data logger (0-100% LEL) / Model number MI1KY-3111H2M-1
The MI1KY-3111H2M-1 offers two types of hydrogen detectors that measure low concentration hydrogen gas levels from 0 to 1000 ppm or high concentration hydrogen from 0 to 100% LEL. It features a built-in suction pump, allowing for hydrogen gas concentration measurements in narrow spaces by connecting a hose to the nozzle. Additionally, it includes an alarm function that emits an electronic sound at two specified hydrogen gas concentration levels, a zero calibration function, and a backlight display function that allows measurements to be seen in dark environments.
