How To: Hanna Instruments GroLine® HI9814 pH/EC/TDS Meter Tutorial

Waste of money going back to blue lab

If have lots of cash to burn get one of these meters as they are pretty good. The TDS probe does not wear out anywhere like as quickly the PH probe, but as they're combined you will have to replace the whole combo probe, at huge expense.. My advice get separate meters, most PH meters have short lives, and then there is the cost of calibration, storage and cleaning fluids, another small fortune. Its like the whole printer and ink cartridge scenario but having to buy a new printer too... Ask me how I know? On my 6th HANNA PH meter, used their range from £450 down to £65, they last from 6/9 months maybe a year for the more expensive type...Be warned!

That sucks, i get 2 years minimum from an essentials brand ph meter at the cost of £45, never used there ec meter as i use a Nz truncheon

Can we take data from this to a microcontroller?

[@Bakumatsu1]

Bought a meter and the probe came dried out and salt crusted. No amount of soaking in storage solution or cleaning brought it back to life, dead on arrival. Waste of several hundred dollars

in aquaculture, we dont need EC, why not change it to Salinity instead ?

Can I use soil slurries for this pH Meter?
