Hydros pH probe

[blkhawk10]

I just calibrated my hydros probe which is a milwaukee probe for the first time with the 7,10 and 4 solutions and now my pH is reading 0. Is the probe broken or is there a waiting period? Before I calibrated the probe it seemed to be reading accurately when I compared it to the salifert test.

put it back in one of the calibration solutions. If it still reads 0 it might be broken or disconnected. If it changes but to the wrong number then something went wrong with the calibration procedure

^^ what he said.

They seem pretty sturdy to me, I'd also check where it is connected to the controller.

What are your calibration values for each cal point? The pH 7 point is the offset and is in millivolts. The other two are for gain and are in percentage.
