YINMIK pH Meter, Digital pH Tester for Hydroponics, pH Temp Meter with Horizontal Display for Pool, Spa, Hot Tub, Indoor Plants, Koi Ponds, Drinking Water, Wine Beer Making, Aquarium, Aquaculture: desertcart.com: Industrial & Scientific

Review: The YINMIK YK-P01 pH Meter Completely Transformed My Hydroponic Garden - I purchased the YINMIK YK P01 pH Tester Digital pH Meter several months ago for daily use in my hydroponic system, and it has become one of the most valuable tools in my setup. After long term, consistent use, I can confidently say this meter delivers excellent real world accuracy, dependable performance when properly maintained, and outstanding value for the price. For growers, aquarium hobbyists, brewers, or anyone who needs reliable pH measurements, this is an exceptionally solid choice. The YK P01 includes everything needed to get started immediately. It comes with calibration powders for pH 4.00, 7.00, and 10.01, three LR44 batteries, a dropper, and a protective cap with an internal sponge designed to help keep the probe hydrated. The large backlit horizontal LCD displays both pH and temperature at the same time, making readings easy to see even in low light conditions. Features like automatic temperature compensation, fast response times, and a hold function make testing quick and convenient, even when checking multiple reservoirs. This is actually my second YINMIK meter, and my first experience taught me an important lesson about proper care. I initially made common beginner mistakes, such as failing to rinse the probe after use and allowing the glass bulb to dry out, which caused readings to drift over time. When I contacted YINMIK customer support, they were outstanding and immediately sent a replacement at no cost. That level of service says a lot about the company. With the replacement unit, I followed the care instructions closely, calibrated it using the included powders, and the performance has been excellent ever since. Calibration takes less than a minute, and the readings have remained consistent and reliable. In hydroponics, maintaining proper pH is critical. Even small swings can quickly lead to nutrient lockout and visible plant stress. Before switching to this meter, inconsistent readings from a cheaper tester nearly cost me an entire crop. Once I began using the YK P01, I immediately identified an out of range reservoir, corrected it, and saw clear improvement within hours. Since then, plant health, root development, and overall growth have improved significantly, and I now have full confidence in my readings. Proper maintenance is essential with any glass electrode pH meter, and this one is no exception. I rinse the probe with distilled water after every use and keep the sponge in the protective cap lightly moistened using pH buffer or a storage solution. The meter does not include a carrying case or a dedicated storage solution, so I store it carefully and recommend purchasing a small pouch if you plan to transport it. I recalibrate about once a month or before important measurements, and the process is simple and straightforward. When compared with significantly more expensive brands, the YINMIK YK P01 holds up remarkably well. When calibrated and maintained properly, readings consistently fall within about 0.1 pH, which is more than adequate for serious hydroponic, aquarium, or water testing use. Its compact size, durability, and dependable performance make it well suited for daily use in humid or demanding environments. In summary, this pH meter delivers accuracy, reliability, and peace of mind at a price that is hard to beat. It has saved me time, prevented costly mistakes, and greatly improved my confidence in managing pH sensitive systems. Take care of it, keep the probe hydrated, and it will serve you well for years. Highly recommended.
Review: Great little meter. - Great little meter. The solution stays good well over 15 days. It will give super accurate results if you calibrate with all 3 solutions, but since I only need +/-.1 accuracy, a once or twice daily calibration (which takes 15 seconds) if sufficient for me.

## Features

## Questions & Answers

**Q: What is the ph range of this?  i dont see it in the listing.**
A: pH range :0.0-14.0pH 
Temp range: 32.0-122.0℉; 0.0-50.0℃

**Q: I know the thermometer on this device only goes up to 122 degrees f., but will it give me a ph reading at 140 degrees f.? what is max temp tolerated?**
A: The operating environment of the meter is 32-122 degrees Fahrenheit, but temp.  can also be displayed if the temperature exceeds this range.
Because the pH probe is made of glass, we do not recommend using it above 122 degrees Fahrenheit, as it will affect product performance.

**Q: How do you know which one to calibrate to?  I just want to make sure my well water is the proper ph-alkaline**
A: If you need test acidic solutions, calibrate the 7.0 and 4.0 points,
If you need test alkaline solutions, calibrate the 7.0 and 10.0 points,
If you do not know the pH of the solution being measured, select all three points for calibration, 7.0, 4.0, and 10.0.
Please note that you  need to calibrate 7.0 first and then the other points. Follow this video for calibration steps.

**Q: When i store this for the winter, does it have to be stored above a particular temperature?**
A: I've never had an issue with temp, Remember to remove the batteries before you put it away for winter

### ⭐⭐⭐⭐ Works, but sometimes readings are all over the place and don't stabilize even after calibration.
*by R***0 on July 18, 2024*

Update: This has never been extremely accurate. However, I was able to use it to get an idea if one acid solution made with vinegar and citric acid is more acidic than vinegar or lemon juice alone for example when canning. I can also use it to determine if TDS filtered water is generally more acidic or alkaline after filtering. There is a pad inside the lid that according to the instructions should stay moist at all times. This pad quickly became moldy and I removed it. The lid was washed and sanitized in a bleach solution. The lid and probe areas still smells strongly of dusty mold so I would never stick it into ready to eat food but rather pour off a sample to test. I have never kept the probe moist as recommended. The probe has never cracked or dried out. I also have never calibrated it since the first time I used it. Surprisingly, It has not needed it and gives same range of readings it always has with the same solutions. Like I said, while not completely accurate it is close enough for home use but is not quick to adjust or respond when being moved from different solutions. Calibrated correctly, so I know that it can determine PH correctly. When testing white vinegar, (5%) it read correctly. However there are sometimes when testing liquids like coffee or water that the readings don't stabilize. For example, when testing a cup of alkaline water, the reading measured 8.6. It gradually over the next 2-3 minutes dropped incrementally until the water had a PH of 6.2. I stopped watching it at that point. I repeated this test multiple times. So either the water is alkaline (over 7) or acidic (under 7) or neutral (7.0) or none of the above. It was hard to know for sure. If you are using this to measure PH of drinking water or filtered water, or using this for critical applications that require accuracy, I would recommend a PH testing alternative that is more reliable and accurate, even if it costs more. Note that the instructions say to shake the instrument side to side to release any bubbles that might be trapped underneath where glass probe is to get accurate readings. I can assure that this was done with vigor and is not a factor in the erratic behavior of the device I describe above.
