Mine still ok... My probes never out of water unless maintenance, and so far only calibration check twice after 5 month using. I am still depend to hydrometer (red sea brand) for water change and this meter for tank water monitoring.
I own a refractometer & ph pen too... but very seldom use.... I still feel meter beside the tank is more convenient...
Base on the user feedback so far....
1x complain Salinity inconsistency but PH ok. But do not know what is the condition now?
1x Encounter Meter blackout a while but back to normal after that. I suspected may due to battery intermittent contact issue or intrinsic prob..
Hopes above helps...
No sure, mine simple sps & lps.. looks ok.. better dont add if doubt.. I only use a few day.. Still left plenty.. AM used this for their show tank.. I believe it shld be fine if use according to instruction.. Cheers..
