I ordered this meter earlier this year, a model 300 that measures both pH and dissolved solids. Unfortunately they sent me the Model 100 which only measures dissolved solids. However, I didn't realize this until I opened and discarded the packaging and other materials. I am now ordering another one but it was a costly mistake. I believe it was a simple mistake - both mine and the seller's. -- but the two meters look very similar, and it's easy to miss until you dip the meter in water and realize it's not measuring PH. I like the 100 model and don't mind having a second gauge to test my primary ones. I will update this review after the 300 ships and compare it to my Blue Lab monitor.
