This pen filled the roll incredibly well. The included temperature gauge is an amazing value and seems relatively accurate. I have not tested the temperature against another meter. The other brilliant feature is the backlight display that auto shuts off after about 10 seconds. you can still see the reading, but the backlight turns off to save battery. accuracy - this pen, When tested against my Milwaukee ph pen shows a difference of only .1, this is without calibrating the YINMIK ph meter out of the box. reliability - used for only about a month so far without issue, will update if it fails. accidentally fully immersed the meter in water for 2-3 seconds. dried the exterior and it remains fully functional. support your local brands when you can, but this is a GREAT backup pen.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value *by T***Z on February 17, 2024* I needed a quick replacement when my other ph pen died.

Highly recommended for both beginners and experts! ### ⭐⭐⭐⭐ a good buy *by B***A on April 9, 2026* Pretty good meter, it's fairly accurate, easy to use, it is as durable as most any glass ph meter which means you need to be gentle with it. To keep it in good working order it should be kept with a 1 molar KCL solution in the cap. Do not store it in distilled water, just as any other glass bulb ph meter. I have several of these types of ph meters and have one that I paid about ten times as much for and this meter seems to be just as good. You just need to calibrate it once and a while. The following is from the net: "To prepare 1 Liter of a 1 Molar (1M) KCl solution, dissolve 74.55 g of potassium chloride in approximately 800 mL of distilled water, then dilute to a final volume of 1 L" I would give it five stars if they included a couple of packets of KCL to make a one mole 250ml solution. But that stuff is easy to come by but you have to a little scale to weigh it. ## Frequently Bought Together - 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 - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - YINMIK 15 Pack PH Calibration Powder, 5 Each for PH 4.00, PH 7.00 and PH 10.01 Calibration Buffer Powder, PH Tester Calibration Packets for PH Meters --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/479304898-yinmik-ph-meter-digital-ph-tester-for-hydroponics-ph-temp](https://www.desertcart.co.uk/products/479304898-yinmik-ph-meter-digital-ph-tester-for-hydroponics-ph-temp) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
