Review on High Accuracy Pocket Size Digital PH Tester Pen for Water Hydroponics - 0.01 PH Measurement Range Ideal for Household Drinking, Pools, and Aquariums (Blue) by Nicole Mcleod

Good day to everyone reading this review! Today I want to tell you about a very interesting device that I purchased in China, namely, a portable PH meter. Many of the readers probably do not even know what kind of animal it is and what it is eaten with. In this review, I will try to tell as accurately as possible about the device and its scope. First, let's get acquainted with the device visually. The device is supplied in a convenient plastic box, which prevents damage during transportation. Inside the box is the PH meter itself, instructions in English and 2 bags of calibration solutions. Calibration solutions must be diluted with demineralized water. They are in 2 ranges at once, for better calibration of the device. The instruction is in English, but in general it will not be difficult to understand. The device is initially calibrated and can be used immediately. The device itself looks like this. The device is powered by two LR44 batteries, which, as always, Chinese friends did not put in the kit. As I said earlier, the device is immediately ready for use and we will try to measure the PH-value of my water from the well. The readings of the device indicate that the water from my well is neutral, closer to slightly alkaline. In general, acidity is normal. Now it’s worth explaining what this desired PH indicator is. Simply put, it's a hydrogen indicator. PH equal to 7 is considered neutral, everything below this level is acidic, everything above is alkaline. So if we see on the device an indicator equal to, say, 10, we have an alkali in front of us, but if we say an indicator of 2, then this is an acid. Now let's talk about the scope, or even more precisely about why it is needed at home. Firstly, by means of this device, you can control the quality of the water or other liquids you use. For example, the Ph indicator of quality milk is 6.5-6.8, if the milk is diluted, then the indicator will be less - 5-5.5. It's the same with almost all liquids. Secondly, this device will be useful for aquarists. The point here is that the pH of the aquarium water directly affects the vital activity of the flora and fauna in it. The same goes for large ponds. For example, so that the water in the pond does not bloom, it is necessary to add acidic peat to it, the simplest algae do not like an acidic environment and will die. This fact has been tested on our own pond. Before the introduction of peat, they didn’t use any chemicals, but everything turned out to be just peat. After the introduction of peat, the water in the pond remained clear throughout the summer season. It is not for nothing that the water in peat reservoirs is clear and does not bloom. Thirdly, the device can be used in winemaking to determine the acidity of raw materials, in particular grape juice. I have listed the main areas where I will use it, but in fact there are many more. With the price of the device in China about $ 9, you will receive a universal determinant of the quality of your products. In the modern world, it is necessary to monitor the quality of the products we use, this device undoubtedly helps us in this. The only difficulty in using this instrument will be the preparation of calibration solutions. Since the quality of demiralized water is difficult to control. But I think, with strict observance of the instructions, this can be sorted out. In the bottom line, I consider the device useful in household use and feel free to advise it for purchase. It will help you keep track of your health. Tell you which foods are bad. It will be especially useful for people with a violation of the acidity of the gastrointestinal tract. Thank you for attention! Take care of your health! I hope this review will be useful to you!
