PH Value Controller with Probe PH2010, Digital pH Meter Monitor and Automatic Power Switch Regulator for Aquarium, CO2 System and Hydroponic Water Control

Muy buen funcionamiento

Unit cycles on-off at the ph set-point. Cannot be good for the co2 regulator and probably only a matter of time before it takes out the solenoid valve. Needless to say this one is in the trash as soon as the new (different brand) controller gets here.

This ph controller is very precise and so easy to setup. Has a relay output to control co2 valve.

Generally works well. I do notice occasionally that the CO2 bubble counter is active long after the ph drops below the set threshold. For the price I’d order again.

Just as accurate as similar products that cost several hundred dollars more

set the desired pH for my planted tank to 7.50 pH then switched the switch back over to see the pH read out. While I noticed the co2 was still running when my other devices were reading the pH value out at 7.46 I looked at the pH controller it was reading out at 7.50 pH, checked the set value expecting it to read out what I have set it at, but no I find it set at 7.30 pH.. confused, switched back over to see what it is reading out at still says 7.36, so I calibrated the pH, but I happened to notice the whole controller is finicky a single light tap on the controller the ph value and set value jumps at most .50 difference, also happened to noticed that the switch from the Ph read out to the set value, the pH set value fluctuates, when i caught that, just wiggled the switch lightly and it fluctuates even more severely. spent a-lot of time adjusting this, being skeptical about this controller I let it be overnight and woke up this morning to the co2 still running, checked this pH controller the pH read out says 7.46 the set value still set at 7.50 looked on my other device it says 7.50. Baffled i go to the Ph controller and tapped it lightly dead center on it and BOOM the co2 turned off...... guess this controller is not as trustable as I thought it would be otherwise I was going to post a 5 star.... thinking of returning this device :/

This PH Meter Controller worked great for the first 5 months. However, 2 days ago it started messing up. It showed my Ph between 3.4 & 5.6 in which all living things would die. I tried calibrating it several times with no success. The real Ph is 7.0. I will have to go back to using my timer for my CO2 tank.
