yep the 802 is the one I have,, the probe needs stored in a bottle of storage solution when not in use, rinsed before useing and before returned to storage,
I believe it can be left in the nuit solution,,this will also cause the EC barbs to corrode
you will need a small 9 volt DC power supply,or the batt. will need replacing often
The cheap generic probe is only Ph not a combo,but the EC probe barbs can be cleaned many times

check out the tri-meter by nutridip,it has seperate probes for Ph/EC, and useing the $35 generic probe makes it cheaper to maintain
Daddynobucks Reviewed by Daddynobucks on . someone help a first timer pls its going to be my first hydro grow pretty soon. im doing a switch from soil to ebb flow buckets with a 55 gal. res. i was just wondering if someone could tell me what ph/ec meter is good for this setup. i want a meter that i can just drop the probes in and get a constant reading. also want a brand i can trust that any hydro store will have replacement probes if needed. i seen some hanna's out there but dont want to get those cause i heard they do a different conversion on the ec readings Rating: 5
