Absolutely love this meter!!!....it’s the best I’ve ever owned I’d buy this again if I needed one but this thing is made like they will quit making this model before then lol 😂.....seriously, I’ve bought several products from Vivosun and I know I can trust it will always be the best quality on the market....I’d love to try more grow equipment from them, maybe a par meter or something if they make one

This ph, etc, and temperature measurement device is very easy to use as well as convenient. Easily transition from ec to ph to temperature without switching to another monitor. You can even use its cap to put water and place the cap on and get a reading while it stands on its own.

Next generation of PH meters. Easy to use and read! Back lit as you can see. Also gives temperature of water and PPM. Much better than the cheap meters that all look the same. Glad I purchased this

This is a great all in one hydroponic meter. This includes a pH (potential hydrogen) meter,TDS (total dissolved solids)meter, EC (Electric conductivity and finally a reservoir thermometer. Save time and gather all your information at once. You’re gonna want to calibrate it after a while or if you’re getting unusual readings. thats typical maintenance. Rinse sensors with clean water after use so that solution does not build up on electrodes and sensors. Sturdy design and a backlit digital display face.

The meter is pretty accurate. I used my current meter as a base to test the accuracy. This meter is meant to be a back up, in case mine goes out. It's built pretty solid. Easy to use. It has 4 functions EC/ppm/temp/pH. Everything seems to be working great. Comes with a battery already installed. Has a background lit screen. Also the pH packets to calibrate the meter. Overall I'm pretty satisfied with it.

The accuracy from my experience with many PH meters is spot on. I tested it right out of the box before calibration and it really seemed like it was calibrated from the factory, but don’t mark my word on that. Much easier to read then past meters I have had and even includes ppm testing and calibration solution! You can’t beat this price for everything you get, with Vivosun they also back their customers and I have faith in that.

Bad, like REALLY BAD. I just finished calibration on both - using the provided solutions..and not only is the PH inaccurate on both meters - the water temp is wrong on them. This is a really messed up situation.

This is equivalent to the other pH meters that retail for $100 or more. Its accurate to .01 and even takes temperature into account when calculating pH. Easy to calibrate and vivosun was nice enough to include free calibration solutions! 2 weeks in and it's still calibrated perfectly.

My unit showed up calibrated and measuring on point. Beautiful design and super bright LCD. Very easy to use and switch between modes. Now I can check my pH and PPM without switching testers. Comes with battery's and everything you need to start testing upon arrival 👍

I bought this meter to test my Ph and PPMs of the nutrients I give my plants. I was using Ph strips prior to purchasing this item, but it was very difficult to get an exact or accurate reading. With the Vivosun 3 in 1 meter I can now get the precise measurements of my water temp, ph level, and ppms all in a single device. It is extremely easy to use and comes with ph solutions to calibrate your meter. I highly recommend this product and would buy again!
