A dashboard for the fish tank. *by on Reviewed in the United States October 3, 2022* Hey. I like this. I have it wall mounted. It is accurate. I have another pH meter by a different maker and it is amazing how close the numbers are. It tells me it's working. The thermometer is accurate and gets readings similar to three other thermometers in my tank. And the TDS display is right in line with two other hand held TDS meters that I use. I wouldn't hesitate to recommend this. ### ⭐ ph probe was dry, ec wont calibrate *by on Reviewed in the United States August 5, 2026* when i received this there was no damage to the box or shipping container, the ph probe had a tiny plastic cap and was shipped dry. with no moisture the ph reading was off and would not stay stable (compared to a milwaukee mc122 pro that was recently calibrated and had a new probe as well) and the ec calibration was impossible. once calibrated to the 12.88 solution the verification solution would read less than 1, instead of the 1.41 it was supposed to. after cleaning the probe and returning it to the 12.88 solution to double check, it swung up to 13.9. recalibrated to 12.88 and then the verification solution dropped from .9 to .7. this leads me to believe either faulty electronics or very low quality probes. considering the ph probe shipped dry, QC seems pretty low. im returning and going with a different meter. ### ⭐⭐⭐⭐⭐ Best tester for the price *by on Reviewed in the United States February 9, 2024* Hi after doing a massive search on amazon for meters i stumbled on this magnificent item. straight out the box it is pre calibrated as per the company's specs but also include the calibration solution to fine tune it to your exact needs, This was brought so i no longer have to test my reservoir ph it. now i have accurate reading witch increase my plants hippieness. overall the best product i brought 5 *****'s ## Frequently Bought Together - 5-in-1 Water Quality Multi-Parameter PH EC CF TDS (ppm) Temperature Test Meter Backlight, Wall-mountable Rechargeable Continuous Monitor Tester, Aquariums Hydroponics Pool Fish Tank Pond Drinking - General Hydroponics pH Control Kit For A Balanced Nutrient Solution --- ## 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.com.sa/products/147536050-5-in-1-water-quality-multi-parameter-ph-ec-cf](https://www.desertcart.com.sa/products/147536050-5-in-1-water-quality-multi-parameter-ph-ec-cf) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-23*
