So, after I ordered the TDS AI213 meter, I received 2 really cheap pH meters. No seriously, 2 Apera PH meters that look nothing like my other PH meters or TDS meters. I really hope I get a reasonable refund for this. I use for hydroponics and really need a counter. It was just stupid of Aper. For example how to mix 2 yellow cheap PH meters with a white/green TDS meter.
