To calibrate your pH Meter, please follow the steps below. 1. Before calibration, add the pH4.00/pH6.86/pH9.18 buffer powder to the beaker with 250ml of distilled water, then stir until the powder is completely dissolved. 2. Place the electrode into the pH4.00/pH6.86/pH9.18 standard solution and wait for the reading to stabilize (usually 510 seconds); 3. Press and hold the MODE/CAL button and release after 6 seconds; Wait until the pH4.00/PH6.86/PH9.18 reading stops flashing. 🌠Packing List: 1*pH Meter for Water 3*pH Calibration Powder 1*Instruction Manual ## Features - πŸŠπ‘¨π‘Όπ‘»π‘Άπ‘΄π‘¨π‘»π‘°π‘ͺ π‘ͺ𝑨𝑳𝑰𝑩𝑹𝑨𝑻𝑰𝑢𝑡 𝑷𝑯 𝑷𝑬𝑡: With high sensitivity glass probe, you can get a full measuring range of 0-14pH, 0.01 pH resolution.

I wasted 32 bucks.Ease of Use:- It's not easy to use at all. The directions are also confusing.- Cannot calibrate the thermometer, which is bad, because the thermometer is wrong.- Batteries are almost impossible to remove.Accuracy:- It claims freezing water is about 70F, or sometimes 25C. My other thermometers correctly read 32F or 33F.- pH levels are inaccurate - compared the results of this meter to the results of pH strips and General Hydroponic's pH kit. Those were accurate, but this was off by a pH level of at least 1 or 2.Feel:- Feels cheap and light.Outright lies:- The instruction manual says you can replace the electrode. My unit does not allow this.Either way, this product is a scam. It's using reviews from a different product to sell a terrible product. I hope Amazon fixes this. Awful product. Do NOT buy. ### ⭐ This is for a ph meter, not straws. Does not work *by L***E on November 3, 2023* Very sneaky of company to use a straw listing to change to a ph meter listing so it looks like it has good reviews. Amazon should not allow this to happen, very deceptive and lowers my trust in amazon. The ph meter is junk and widely inaccurate. It was impossible to even calibrate since the reading change everytime you use it. It tested my tap water anywhere between 6.2 and 8.9. I don't mind it being a little inaccurate, but this isn't usable at all. Waste of time, I now need to order a different brand and return this one. Two thumbs down ### ⭐ Don't Buy *by C***L on December 5, 2023* BEWARE. I bought 3 of these PH meters and ALL of them were defective - Plus I have to pay for the return shipping. Each of these had a different PH reading from 4 to 8, after calibrating. I compared to two high end meters and they were way off. They would kill my discus fish if I used them. Reviews are WRONG - they are about a different product. These are awful. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/572040040-4-in-1-ph-meter-ph-meter-for-water-digital](https://www.desertcart.pl/products/572040040-4-in-1-ph-meter-ph-meter-for-water-digital) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-30*
