VIVOSUN PH Meter, TDS and EC Meter, Soil Tester Combo

This is a really great product, all the meters work very accurately. I'm reading the instructions is very important to fully understanding the devices. Easy to read easy to operate, again very accurate. I am very very pleased with these products, they have made my growing experience far better than I actually imagined they would. There's really not much else to say. I do recommend ordering directly from vivosun so you don't have to wait 3 weeks to a month for them to be delivered.

Super cool comme instrument

Nice combo, the PH meter was broken but was refunded and I got a replacement.

I have owned this Ph and TDS kit for about three weeks now, and so far it seems to be holding calibration well. I compared this PH meter to my friend's high-end PH meter and was pleased to see they only differed in readings by a very small amount. I do recommend storing the PH probe in H2O Sync pH/ORP Electrode Storage Solution or another similar product. to maintain the accuracy and longevity of the probe. And would also recommend periodically calibrating the probe using BOJACK 15 Pack of pH Meter Buffer Solution Powder for Precise and Easy PH Calibration. All of which can be purchased on Amazon for a small price. If you are checking the PH and TDS levels of water for watering plants, then this is an inexpensive and pretty accurate way of doing so without breaking the bank.

Easy to use, quick shipping extra batteries and sample size chemicals.Easy Peasy
