All the great reviews, so I wanted to see what all the fuss was about. The biggest difference I can see when using this unit, is that the PH readings are much more accurate when the water is at different temps. The water is very cold here when it first comes out of the tap. This is when I notice the cheaper meters are very inaccurate. When the water warms up to room temperature, the cheaper units get more accurate.Bottom line; Most gardeners retrieve water from the tap and immediately mix their nutrients. So they don't get accurate readings. The Bluelab unit is WAY more accurate through all temperatures. This way, I get a much more accurate nutrient mix right off the bat, and don't have to worry about PH swings so much after the rez water reaches room temps.The calibration of the unit is very simple and straight forward. I now own 3 of these, and am getting ready to buy several more for my farm to table dispensary in northern MN. ### ⭐⭐⭐⭐⭐ This thing is awesome!!!! 🔥🔥 *by on Reviewed in the United States May 3, 2026* I honestly don’t understand the bad reviews I’ve seen — most of it seems like user error. They say they can’t connect it to the Edenic App, but they’re missing one key step: you have to put the Guardian into PROVISION mode first (Settings → Temp button) before pairing. Almost like it’s not written in the instructions!Once it’s set up, it works flawlessly. I get real-time updates on my phone if anything drifts out of range, so I can fix it before feeding and avoid pH lockout issues.Super reliable, super convenient, and gives real peace of mind. Definitely worth the money 👌I really wanted to spend the extra to go with the PH dosing model but unfortunately it’s missing a sensor probe that I needed ### ⭐⭐⭐⭐⭐ High value for price for the "prosumer" market *by on Reviewed in the United States February 5, 2025* I only read negative reviews to gather my opinions on a product. If you're serious about buying a product like this, consider that pH probes are not a lifetime investment due to their nature, and move on with life. This unit has a permanently fixed EC sensor, and a replaceable pH sensor. I've purchased two of these units. The first came out of the box and required no calibration as far as I could tell. The second unit came with a defective pH probe (again reference why these probes are problematic in general regardless of manufacturer)...Immediate and awesome response from Bluelab support and they are sending me a replacement probe with no issues. The reviews I've read about this company are consistent with my experience, and I cannot recommend them more.If you want to integrate your own app with their API, it's braindead simple. I cannot recommend this product more. ## Frequently Bought Together - Bluelab Guardian Monitor Wi-Fi for Real-time pH, Temperature, and Conductivity (TDS) Measurements in Water with Calibration, 3 in 1 Digital Nutrient Meter for Hydroponic Systems and Indoor Plant Grow - Bluelab pH 4.0 & 7.0 Calibration Solution Kit - pH Meter & pH Pen Calibration for Balanced Nutrient Solution NIST Traceable | Hydroponics, Gardening & Growing Tents (500 ml/ 16.9 Fl Oz Each) - Bluelab PROBPH pH Probe for Water, Replacement Electrode for Meter, Monitor, and Controller with Easy Calibration, Tool for Hydroponic System and Indoor Plant Grow --- ## 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/549627173-guardian-monitor-wi-fi-for-real-time-monitoring](https://www.desertcart.hr/products/549627173-guardian-monitor-wi-fi-for-real-time-monitoring) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-17*
