Expensive but imo worth it.
Replaceable probe, long lead and fast readout. The display is not water proof though

Also you need cleaning and calibration kits and storage solution. It costs a lot up front but is worth the money in my opinion

It also does direct soil or hydro ph measurements

Did you buy the calibration solutions and cleaners? It's very important to keep the probe wet during storage in kcl solution and rinse off after each use , calibrate and clean monthly

I habe bought PH 4 and PH 6.8 250ml calibrate solution and today KCL solution too. A Freund told me the PH it's best to store it in PH4 solution and 1 times a month store in KCL in 24 hours than Calibrate again.

You need to get the cleaner solutions too. The probe will not calibrate correctly if you don't clean it proper

Glad you're getting your new probe!

Cleaner solution?

I've not seen that in any manual, just rinse and store in proper storage solution.
If you look on their page they sell a cleaner solution. If your probe is dirty it won't be a precise calibration. Maybe the brand you have doesn't have it in the instructions but cleaner solution is a thing, if I didn't have it I would still use a soft nylon tooth brush and some sort of natural cleaner to make sure there is no gunk built up on the probe

Here is the solution the site for the probe feite ordered


Also bluelab has a cleaner kit for the ph probes and ppm probes which is how I found out about it

This Adwa Electrode is a Piece of Shit!!! After the second buy the next electrode is damage after good calibration and KDL storage the electrode show a ph 8.0 solution under PH 2.0 and don't let it calibrate again what a shame....

Yeah i have no experience with that probe

But all the other stuff you bought should be universal I hope

Make sure to reach out to them, and ask for a return or replacement
