Spend the money
Style: pH/EC/Temp Meter in Multiple Substrates
Love this meter, reads fast, does EC ppm 700 and 500 Some nutrients use ppm500 scale others use ppm700 scale The ph meter does a 2 point calibration Don’t waste your money on cheap ph pens.

Just buy it, already! Worth every penny.
Style: pH/EC/Temp Meter in Multiple Substrates
I have had this product for about 10 months now, it is by far the best ph meter I have ever used. Taking slurry samples and testing soil ph has never been easier. Its all in the one controller and its super easy to calibrate. I keep the probe in the storage solution and it works wonders, last night I went to calibrate my meter for the first time in around 6 months and it read 7.0 and 4.0 spot on.. I used to have to replace cheap meters every 6 months and who knows how accurate those readings even were.. Inspired me to come write a review! ... show more

A very important tool to have for a Gardener
Style: pH/EC/Temp Meter in Multiple Substrates
Love it!!! Fast and easy! Much better than my pH pen. It will make a good backup. This meter rocks! User friendly! It's nice to be able to stick the pen into tops like a milk jug to check. No more having to pour a test sample. Not to mention the ability to easily check the pH of the soil!

Very accurate...Way too expensive.
Style: pH/EC/Temp Meter in Multiple Substrates
I love the accuracy of this unit. I find that I don't have to calibrate as often as the directions say. This is more of a professional unit. I should have just got a cheaper Bluelab unit. However, if I expand this unit can meet my needs for all grow mediums. My only complaint is it just cost way too much. If you are a home grower, do not buy this. Buy one of the cheaper bluelab units....like well under $100. But definitely go with Bluelab. ... show more
