5 of 5 people found the following review helpful By Ken J. Stager on June 12, 2013
So I was quite skeptical over buying this meter at first. Between there being no reviews I could find, and the low price attached to it, something just seemed off. So I went and took the plunge. I must say I'm impressed. The meter itself is heavier then expected, with both construction quality and weight. If you are thinking you want a nutrient monitor, let me just say you do. I just never realized how much I wanted one till this meter showed up. The pH and PPM calibration was a snap. I will say though that I didn't use the supplied check solutions, and used my blue lab products I had on hand. The first week I had to tweak the pH calibration ever so slightly, but after that it stays put. At this point, my meter hasn't needed calibration in over 2 months, it still is reading true to 4.0 and 7.0. The PPM adjustment is a little trickier, make sure you have enough solution to full submerge the electrode, it seemed slightly finicky in that department. And also take your time adjusting it, because the calibration screw is VERY sensitive. I've never calibrated the temperature, because they seemed close enough, and that really doesn't demand the tolerances pH and PPM does when you're floating right around 70 degrees anyway. There is an adequate amount of cable to run the sensors I'd say about 5-6 feet, and the connections were very firm. With me being me, I tested the meter against my handhelds for about 2 weeks, before I finally realized there wasn't any point. As long as you calibrate this meter correctly, it will read true. You don't even know how bad you want one of these yet. There is nothing better then just popping open your cabinet and knowing your conditions without even lifting a finger. A meter now seems like a must for any serious grower. I'd recommend this to my grandmother if she had a need for it.
