Review on Gain Express 1999-1999MV Temperature Gauge 0-14PH by Ricky Cruise

I bought this because there are more pros than cons. And for the price. I just didn't expect it to be so difficult to work with and understand. For the beginning; The instructions are vague for the first time user. Second, to start the calibration, you must immerse the meter in the proposed liquid and wait for a stable reading before proceeding. If you can watch the video I posted you will see that the reading has not stabilized and we are moving to the third day. Yes, it is in the same 7.0 solution for 3 days. I intend to ask for a refund please. I need this for work and it needs to be accurate. Not worth $. The search continues.
