Yet another Hanna Salinity Tester thread

[CrayHawk]

Hey guys - I have a Hanna Salinity Tester that has served me well for a couple of years now.

I tend to calibrate every month. Earlier this week, the tester will read the temp, but salinity stays at “1.000.” I recalibrated again and it read the correct 1.026 the first time I put it in the tank water. Once it powered off and then back on, it read 1.000.

Thoughts? It may be time to purchase a new unit but I’d like to save the $70 if I can.

Try pulling the battery. Probably won't help but I've found removing power to fix weird electrical problem on autos.

Hi CrayHawk,

1) Did you check the batteries?
2) Is your calibration solution bought or self-mixed? Might be more precise mixing one yourself
3) I recently bought a refractometer for less than 30$, no electroncis (and batteries) needed :)
