Review on Bluelab PENPH pH Pen: Accurate Water Digital Meter with Dual Probe for Hydroponic System and Indoor Plant Grow, White by Pamela Beatty

Good after 3 failed blue lab products qll is stocked according to service manual I bought this meter 4 in total this meter was bought overdue to the point of absolute necessity Reading the Ph while waiting for a response from tech support to basically tell me to kiss my ass, days and days went by with no answer to a simple question. So this meter was bought in an emergency, it failed after 2 months. Warranty? Maybe but hell with it they all go in the trash these gauges after being properly calibrated every 2 weeks both ph/tds were absolutely nothing but troublemakers I would have been better off not even using them and a risk enter into. never again. choose wise.
