Review on Optimized 0-14 pH Electrode Probe with BNC Connector, 300cm Cable - Suitable for PH Meter Monitor Controller Test Sensor, Ideal Replacement Kit for Aquariums, Hydroponics, Plants, Pools, and Spas (pH Electrode) by Drew Poulin

Bought to replace my 70's vintage box (see attached picture and let me know if you want to buy it for your museum , I'll give it to you at a good price). The pH meter works fine but I refused to use the probe that came with it. I replaced it with one I've had for over 5 years that still works and behaves like a regular lab sensor. The original sensor was accurate enough, but slow. but the hat is hardly a surprise. Anyone experienced with pH meters knows that the box doesn't matter, it's the sensor that defines your experience.
