Ph water tester needed for fish aquarium tested the accuracy of the pen with PH solution was spot on. The build quality is good but dont press on the screen at all as flimsy. Price is reasonable if you dont want to wait for a chinese product which are cheaper overall if you are looking for a good Digital Electric PH Meter Water Tester Aquarium Water Test Pen LCD from the uk then look no further order one today.

I calibrated the pen using pH 7 and pH 4 buffer solutions as per the instructions. It showed just above pH 7 for hard tap water, then when I added phosphoric acid to the water *the reading increased*. This product is worse than useless, you're better off with old-fashioned litmus paper.

My previous pH meter cost around £40 and was a bad experience. Costing only a few pounds my expectations for this meter were low but for the price I thought it was worth a shot. I can only check accuracy against two liquid indicators but it certainly gives results which agree with them and results are consistent when the same water is tested repeatedly. My only interest is in water between pH5 and 7, I have no experience of accuracy outside of this range. I have been using the meter for around 2 months.

I am happy with my purchase. The device is working well. I have learned a lot playing around with different liquids. I did not expect a green tea to be around 4.3PH. Important thing to remember most of the vegetables, fruits and roots become highly alkaline once they inside of a body. I am not impressed with PH of baking soda. Mixed with water it was stuck around 7.74. I was expecting it to be in the end of range. It looks like I need to learn more about Ph. In meantime, I would recommend " The Tao of Detox" by Daniel Reid. He explains a lot about different type of foods and their effect on our body. Good luck on your journey. Remember even fish in aquarium needs narrow Ph range to survive and thrive. We are no different. I wish all the best health for anyone.
