I have a few tanks and recently really got into trying to understand water chemistry and testing. I wanted a "second opinion" on my liquid pH kits so bought this pen. It seems to confirm, though with great granularity, ease and accuracy, the results of my liquid kits, which I find quite hard to read (I always imagine that I can see the pH colour going in the wrong direction!). I tend to buffer my own RO water and this pen is accurately reading the results of the buffering – for example, I use Lake Tanganyika buffer to raise the pH to 9. I tested with the liquid kit, which read 8.5-9.5ish, whereas the pen was reading 8.9-9.1, as I would have expected. To ensure more accurate alkaline readings, I purchased a 9.18 buffer for calibration – it was only off by a little when it arrived; it was bang on the neutral buffer though! I will continue to use this product and would recommend to others. However, I would say having multiple options to read pH would not be a bad idea, just in case. Originally, I was going to spend £100 on a Hanna pH pen – which has reviews that are also somewhat mixed – and all the buffer, cleaning chemicals and storage solutions that it requires, but thought I'd first take a chance on this pen – for now, this seems to have paid off. Review: A solid choice for kombucha brewers - I bought this pH meter to monitor my kombucha brewing. So far I've found it very handy and can't really fault it for home use. Readings tend to stabilize after about 4 seconds, which is pretty good. Calibration out of the box was off by about 0.15, but the included buffer packets lets you take care of that, which is nice. One thing to note is that the calibration is linear, meaning you basically just set an offset for the reading the meter gives. You cant adjust the scale if it gets off over time, so the meter will be less accurate as you get further from the pH of the calibrant. However, this shouldn't be an issue for non-scientific applications. tl;dr: A great choice for home-brewers, cheesemakers, and more. Calibrate it on first use. ## Features - 【Automatic Calibration】Every Preciva PH tester is calibrated before it was sent to our customers, no need to calibrate again. You can calibrate it every two weeks if it is used frequently, and once a month if not frequently. - 【Automatic Temperature Compensation】Provides full PH 0-14 measurements with temperature compensation which will make the result more accurate. After testing strong acid or strong alkaline liquid, please wash the probe with distilled water before measuring other liquids. - 【Easy to Use】Just need to see the number on the digital display of the PH meter when you are testing the liquid, more efficient and time-saving. If your reading is not stable, please wait for about 1 minute for the liquid to settle. - 【Convenient to Carry with】This hydroponic ph pen is designed based on the handy size that is ideal for carrying in your pocket and test the PH no matter where you are. - 【Wide Applications】Ideal digital pH meter for aquarium, fishing, swimming pool, student lab, tap water and other liquid. Note: The white matter that comes with the product belongs to the characteristics of the product itself. It is safe to dissolve the auxiliary measurement when measuring. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071XFRLSN | | Batteries required | No | | Best Sellers Rank | 16,929 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 18 in Lab pH Meters | | Customer Reviews | 3.9 3.9 out of 5 stars (3,425) | | Date First Available | 15 Jun. 2017 | | Guaranteed software updates until | unknown | | Item model number | PH320001 | | Item volume | 66.12 Decilitres | | Item weight | 60 Grams | | Product Dimensions | 15.2 x 2.9 x 1.5 cm; 60 g | ## Images ![Preciva PH Meter, 0.01 Resolution Digital Pen with LCD Backlit for Aquarium - Image 1](https://m.media-amazon.com/images/I/61nqHPf90wL.jpg) ## Questions & Answers **Q: What do you do with calibration solution? Can I reuse it for future calibration or it gets unstable after some time and useless?** A: Hey it gets unstable and useless I use ph buffer liquid seems to work better for me I don’t mess with the powder solution anymore **Q: Can this be used in hot liquids? E.g to test the acidity of hot vinegar?** A: Sent this item back same day as useless.... **Q: Can deionised water be used to rinse the meter or just distilled water?** A: I bought some distilled water from Halfords which is also deionised (battery top up water) seems to work fine with my meter.!! **Q: Does the clear plastic cover over the electrode have to come off?** A: Thanks for your question. Just come off the black plastic cover and insert to the waster. Then it will show the PH of the waster on the LCD.

Fast delivery, well packaged, robust casing and instructions are easy to use. Everything required for recalibration (even though it comes calibrated). There’s even a mini screwdriver included but it’s a decent one! Very impressed. I should have got one sooner. Update , it’s been only two weeks and the product has stopped working. I’m hoping it’s just crappy batteries but even still I wouldn’t have expected them to run out so quickly. ## Frequently Bought Together - PH Meter Tester, Preciva 0.01 Resolution Digital Automatic Water PH Meters Hydroponics Pen with LCD Screen Large Backlit for Kitchen, Aquarium,Pool, Laboratory with Calibration Powder - BOJACK 15 Pack of pH Meter Buffer Solution Powder for Precise and Easy PH Calibration, PH Calibration Powder Solution 4.01pH,6.86pH and 9.18pH - Distilled Water - 100% Ultra Pure Water (Blue) (1L) --- ## 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.hr/products/48142824-preciva-ph-meter-0-01-resolution-digital-pen-with-lcd](https://www.desertcart.hr/products/48142824-preciva-ph-meter-0-01-resolution-digital-pen-with-lcd) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-03*
