716572 Nutrient Monitor

After sifting thru the many meters and their offerings, I settled on this one because it has all the important features I want to monitor, Constantly, and much cheaper than most for what it does.Shipping was fast, Packaging was impressive, I found the calibration went off flawlessly right out of the box. As the directions say, they were clear and understandable as well, I went very carefully and slowly dialing in the screws calibrating, and there were no problems. Been just over a month now in use and I won’t ever grow hydroponically ever again without 1 - Great Buy Great Investment Great Product Great Relief Always Knowing What Your Plants are Sitting In at a Glance - There’s many to choose from that do the same thing, but for the money you n I spend on equipment, I find this product by far to be above most for value, looks,cost, and you can get replacement probes as well - I recommend and I’d buy again

So far loving it. Was calibrated right out of the box (I checked) and it came with 3 medium bottles of calibration solution.) Seems to react well under 1 second. Green light is very nice. Comes with a power supply. My only complaint is that the probe leads are a little short. They are about 6' long and that was too short for where I wanted to mount it. But most people will mount it above the tank on the wall so it'll probably be fine for 99% of the users. The pH probe comes in a small bottle of storage solution as well. One quirk: the TDS shows 3 digits. Since this will measure over 1000 ppm, it shows only the first 2 digits. Ie, 400ppm is shown as 40. 1300 ppm would be shown as 130. It's marked on the face so you won't forget it, but it's just something to keep in mind. I would prefer a direct read out and some light or something for readings over 1000. ie, 400 would be shown as 400 but 1300 would be shown as 300 with a flashing light to indicate it's over 1000. But that's just my opinion. Once you get used to it, it's not too bad. Also nice is that both the pH and TDS probes are detachable.What comes in the box: Meter, TDS probe, pH probe (in storage solution bottle,) power supply, 3 calibration solutions: pH 4, pH7 and 1382 TDS, instruction manual.

Seems to work well, but the calibration was very finicky. Simply touching the calibration knobs would send the unit into wild fluctuations positive and negative. Getting it to settle on the correct value was pretty much by chance. Once set it’s been working fine. I’ve used back up Ph, temp and EC methods to verify the readings. Overall it’s a real time saver to be able to consult the readout versus manually conducting the tests and readings every day and especially when adjusting Ph and EC.

These monitors work fine. I think they are best for price. That's why I keep ordering them.

Very happy with it. Wish there was an instructional video on calibrating.

This is an other scam you can find online, the product is crap, literally not working at all, opened it plugged it in, the device turned on for couple minutes then turned off for ever. I lost my hard earned money. Stear clear from this item unless you like throwing money away or gambling with 5% chances of winning.
