## Description

Product description Did you know that pH is important because it influences the availability of essential nutrients . Most horticultural crops will grow satisfactorily in soils having a pH between 6 (slightly acid) and 7.5 (slightly alkaline), while a very high EC can quickly lead to plant death. If overfertilization occurs and the is too high, you should immediately flush the substrate with copious amounts of water to remove the salt. Our products are designed for durability - so you can relax knowing that your meter is robust and user-friendly, allowing you to get on with the tasks of everyday growing. Key Features Replaceable pH electrode included Measuring Range : pH: 0.00~14.00pH Proven high accuracy and Auto Temperature Compensation (ATC), comes with removable BNC electrode Replaceable EC electrode included Measurement Range: EC: 0.00~19.99 Continuously monitoring shows readings on its large-screen triple display with backlight Customizable measurement scales for extra convenience Instant Triple Display Of Results Complete Kit Set With PH Calibration Powder & EC Calibration Solution Switchable °C/ °F Temperature Unit Automatic Temperature Compensation Clear LCD With Backlight User-friendly And Easy Calibration Power Supply: DC6V With Rechargeable Battery Installed Weight: 223gms What will you get Calibrates easily and offer safer and precise measurement 1 X 5 In 1 Water Quality Monitor,1 X PH Electrode With BNC Connector,1 X EC Electrode With BNC Connector,1 X 4.01ph Calibration Powder ,1 X 6.86ph Calibration Powder,1 X 9.18ph Calibration Powder1 X EC 12.88 Calibration Solution, 1 X EC 1413 Calibration Solution,1 X Metal Hanging Bracket ,2 X Mounting Plastic Brackets ,1 X Mini Screwdriver ,1 X 110V Power Adapter ,English User Manual

Review: Best tester for the price - Hi after doing a massive search on desertcart 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
Review: Nice. A dashboard for the fish tank. - 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.

### ⭐⭐⭐⭐⭐ Nice. A dashboard for the fish tank.
*by L***A on October 3, 2022*

### ⭐ Good idea, but very poor design. Also terrible Quality Control
*by W***N on December 7, 2023*

If you want to measure the Ph of one container, and the EC of another seperate container, this is for you. If you want to measure the Ph and EC of the same container/liquid this will not work. When I measured the Ph and EC seperately this was spot on. However when I put both probes into the same container/liquid the EC would quickly go out of range and the Ph reading was way off. I suspect that there is an unwanted electric leakage current flowing between the 2 probes when in the same liquid, which is hosing the readings. This should have been caught by the Co. QC department. Bad desigh/assembly for sure.
