HI 98308 PWT [Pure Water Tester] When calibrating, store the meter and solution together for a while so both solution and the meter are the same temperature. Don't hold the solution container tightly in your hand because heat soak from your hand will toss everything out the window. The temp compensation doesn't work the way you'd think it would...and Hanna ain't talking. The PWT is the best of the sorta bad. I have 2 PWTs calibrated the same and they don't agree with each other anywhere on the scale except in the calibration solution. None are very 'good'. Maybe the $$$$$ bench top lab instruments are better..maybe not. But using conductivity to get PPM isn't exactly a valid way to do these things anyhow. It's just better than not being able to afford to do it right. It's better to do the job relatively badly than not at all, I suppose.
