Review on 6 In 1 Multi-Parameter PH/ORP Redox/EC/CF/TDS PPM/Temp by Brandon Skeet

I fell in love with this meter in a very short time. I bought it in May and have been using it since June. It's a very good meter, easy to use. At the end of August I was getting strange readings and trying to calibrate them. The meter is not calibrated and is practically unusable. I think it was good while it lasted! Almost three whole months! Thus, this meter costs about a dollar a day. Good luck if you buy this you will need it!
