Hydroponic Pen 3 in 1

Vivosun 3-in-1 pen. It would get a 5 star rating if it came with all the necessary calibration solutions. The pen is very accurate, I easily calibrated the pen by simply following the instructions. When delivered, the PPM calibration was correct. I bought a separate solution to test this for accuracy. (The only reason I had to give them 4*). Batteries included!

Pros
  • Everything is fine!
Cons
  • Hard to say

Easy to use, easy to read

The measuring device is easy to calibrate. Once calibrated, I always buffered it at 7am for confirmation, and it has been reliable. I love that this pH meter comes with lots of calibration buffers. Easily switch between tds and pH. I prefer these types of probes to corded ones because of their compactness. I removed the asterisk because the pH takes a long time to stabilize and it would be nice if it came with an electrode storage solution and a tds standard solution.

Pros
  • Fingers crossed
Cons
  • Negative impression

Unsurpassed Error - Test, Measure, Verify

The only thing this company is good at is making vibrating 6 inch fans. measured distilled water by weight to ensure the pH solution was accurate and also kept the water in a circulating tank to keep it at an accurate 77 degrees. The meter calibrates accurately to 6.86 but then registers 4.00 as 6.72 and 9.18 as 6.97 and keeps recalibrating all 3 solutions to 6.86.2 out of 3 products I've bought from them similar accuracy/consistency issues; 3rd is a fan and has no measurement. Still, the…

Pros
  • I hold my fists
Cons
  • Seniors

The best on the market, handy

I love this meter so much! It's the best I've ever had. I would buy it again if I needed to but this thing is made like they used to not make this model anymore lol. Seriously, I've bought several products from Vivosun and I know we can trust him. I'd love to try more attachments from them, maybe a setting or something when they make it.

Pros
  • Versatile: The VIVOSUN Pocket & Multifunctional pH Tester is perfect for everyday use, as an addition to drinking water test kits or as a gift for family and friends
Cons
  • Easily torn

Unsurpassed Error - The Ultimate in Substance Analysis

The only thing this company is good at is making 6 inch vibrating fans. This is the third product I have tried from them; I sterilized, purified and weighed distilled water to ensure the accuracy of the pH solution; Water in the circulation tank to keep it at exactly 77 degrees. The meter calibrates well at 6.86 but then registers 4.00 as 6.72 and 9.18 as 6.97 and keeps calibrating all 3 dilutions at 6.86.2 out of 3 products I bought from them had similar ones Accuracy/consistency issues, the…
