VIVOSUN 0 05Ph Accuracy Readout Temperature Review

These two knobs are a bit wobbly. The PH meter has calibration issues but at least I can recalibrate and check it regularly. Oddly enough, it also sometimes starts reading at the other end of the spectrum, like 8.5, and then works <very slowly> down. When this happens I have to leave it running first, then turn it off and on again to test it again, as only the second test can decide the actual PH and not keep going up and down. Bit odd but it works for patient people and I found the kit…

I bought these specifically for ppm and ph tracking and they work great! I use them for exotic gardening and it's extremely important to keep track of these things. I tested both pens, but I use the pH pens every day to make sure I have the right nutrient intake. However, I will use a different paddock when it comes time to pre-harvest rinsing! Some people forgo it, but I think they lose productivity as a result. Paying attention to all of these details is important to maximize potential. I…

Not factory calibrated. It reads a mistaken pack of 6.86 ph buffer solution as 6.50 ph. look at my photo I also tested a glass of water 3 times within an hour and got 3 different readings. First time it showed: 5.52ph Second time: 5.69ph Third time: 5.72ph It might not seem like much but there can be a BIG difference depending on what you're doing for need an accurate pH value. . I bought this because my 2 year old brand "Jellas" worked properly. But it still gives the same reading (6.2 ph) as…

These pens are both a bit nimble. The PH meter has calibration issues but at least I can adjust and recheck it periodically. Oddly enough, it also sometimes starts reading at the other end of the spectrum, like 8.5, and then works <very slowly> down. When this happens I have to leave it running first, then turn it off and on again to test it again as only the second test can decide the actual PH and not keep pacing up and down.

I tested both pens, but I use the pH pens every day to make sure I'm getting the right nutrient intake. I'll use another paddock when it's time to flush before harvest!

Not calibrated right out of the box. It reads a mixed pack of 6.86 ph buffer solution as 6.50 ph. look at my photo I also tested the glass of water 3 times within an hour and got 3 different readings.
