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 Eric Mueller

I've had nothing but success with this pH meter. Cheap yellows keep dying for half of this rider's life. I'm so excited that I can only look at this and. Get what I need. I hope this company does another one with tds/edc! 100% would buy! ;) A word to the wise - clean it in purified or distilled water (immerse and rinse the probe) every few weeks. Keep the tiny water bottle that also contains the sensor. Whenever you flush and refill the tank, flush the probe and then use some fresh, clean water to fill the flask 2/3 full with the probe cap. Then wet the ca0 probe cap sleeve, slide the cap onto the probe, fully immerse the probe into the bottle filled with water, screw the bottle onto the cap. No pH meter likes air. This system removes this variable entirely. I think the 3-cent cover is a really nice additional benefit.
