FQA
Q: What type of battery does the product use? Are batteries shipped?
A: Products generally do not ship batteries, and online logistics cannot transport batteries. The type of battery is: 3 * 1.5V (LR44) button battery. Please buy it locally.
Q: Is it necessary to calibrate the function of the instrument to measure "hydrogen"?
A: The product has been calibrated before leaving the factory. The product cannot calibrate the function of the instrument to measure "hydrogen" by itself.
Q: Why does the "hydrogen" instrument measuring tap water display "0"? When measuring the "hydrogen" of electrolyzed water, the value will continue to change over time?
A: Under normal circumstances, the hydrogen content of water is "0", and the measurement data shows "0", which is correct. Need to use a hydrogen-rich cup after electrolysis, and then measure. The hydrogen content is relatively small, and the measurement data will also display "0". Hydrogen is very easy to volatilize, and the value will continue to decrease over time.
Q: What is the unit for measuring hydrogen? How to convert measurement units?
A: The factory default measurement unit of the instrument is ppb. When the instrument is turned on, press the FUN" key, and the measurement mode will be switched between ppb and ppm. (1ppm =1000ppb)
Q: What should I do if the received product is damaged, cannot be calibrated, cannot work normally, and the meter cannot recognize the solution?
A: Please protect the product and contact us in time to report product problems
Note:
1. The electrode should be cleaned after use
2. PH calibration: 1 point or 2 points or 3 points automatically. If the meter cannot recognize the solution, please replace the electrode or contact the supplier.
3. It has been factory calibrated and can be used directly.
4. After completion, clean the electrode with pure water and keep it dry.
5. Stir gently a few times to ensure that there are no bubbles around the electrode.
6. Do not disassemble the meter without permission.
Troubleshooting:
Ph reset
1. Turn off the meter, press HOLD/TEMP and MODE/CAL at the same time, don't release it.
2.Press ON/OFF, then release all buttons, the reset is complete.
Brand Story

YIERYI brand was registered in 2016. The main products are refractometers, PH meters, tds, ec pens, soil meters, kitchen scales, and jewelry scales. In order to ensure the accuracy of the data, we gave up the low-cost chip, selected high-precision Taiwan imported and South Korea imported chips, the design chose a portable pen-type design, light, beautiful, and easy to carry. All products will be tested, calibrated and used by ourselves to ensure that the quality is qualified and then promoted. We want to let this healthy brand enter every family and every corner of the world, and pass on the dream of "world love, made"!

Great product, seems to work fine with h2 ppm and orp mv readings. Not sure of my ph measurements tally with what i have – need to figure out how to calibrate the device properly.

It works. Finally, I know what pH my water has. And I confirmed the information about H2’s impact on the oxidation potential. It’s worth having.

Item arrived in 20 days and surprisingly includes batteries. I am not sure how accurate is the tool but the measurements look more or less adequate. The english language in the manual is a bit better than the average manuals. The backlight automatically goes off after 10-15 seconds. I have not checked how many seconds does it take for the tool to turn itself off after being idle. Overall i am satisfied.

I have been testing the water produced by various hydrogenated water (H2) production devices, and it works well. The results measured by the probe are consistent. Good quality. I recommend it.

Waterproof is good to use; I have a homemade water ionizer and test pH values with the device.
