Hanna InstrumentsHI 7061M Electrode Cleaning Solution, 230mL Bottle

I think this solution is important to keep the electrodes clean. A must for the tester

I have the Hana Instruments HI 9813-6N multimeter that I use in my Aquaponics set up. To get accurate readings from the probe, it needs to be periodically cleaned. That is what I bought this solution to do.This OEM cleaning solution does what it's supposed to: it cleans my probe.I guess this kinda ends my review.;)

This liquid restored my $200 PH sensor, when the manual said it was shot. I am not making claims that it will do this for you as It was not supposed to be able to do what it did for me but, it worked and what more could I ask for?

I will buy this again

Mehh

Electrode seems clean enough haha. This came in a professional unopened bottle and looks as expected. But you sort of have to trust that it works because you can't really see what it's doing to the electrode :)

Big improvement over former two-part cleaning fluids. Much easier.No negatives.

Good product, good price

Expensive and can only be used about 5 times.
