Easy and convenient dissolved hydrogen meter
The M687MD-XF allows you to easily check the concentration (ppm) of the trending hydrogen water. Instead of the expensive membrane polarographic method, it measures the hydrogen concentration in nearly neutral aqueous solutions using a low-cost reduction potential method.

basic information
■Measurement Method ●Connection Connect the main unit and the probe. Carefully remove the green protective cap from the probe tip without touching the tip with your hands. *Please do not touch the probe tip with your hands as it may cause malfunction.* ●Power ON Turn on the power and immerse the probe tip in tap water or pure water. Confirm that the LCD display shows a value of 0.00ppm or lower. *If the display value does not reach 0.00ppm or lower after immersing the probe for more than 3 minutes, press the flash switch towards the ZERO side for several seconds until it shows 0.00ppm or lower.* ●Reading Immerse the probe in the measurement sample (such as hydrogen water) for a few minutes, wait for the display value to stabilize, and then read the value. If the value does not stabilize, gently shake the probe tip while it remains immersed in the sample to stabilize it. ●Draining Water After the measurement is complete, rinse the probe with tap water, lightly shake off the excess water, and store it with a small amount of purified water in the protective cap.
