So i just bought a hanna 98129 ph/ec/tds meter. I bought hanna hi 7031 calibration solution which is supposed to be 1413 at 25 degree's celcius. Well at 25 degree's celcius its about 1597. Any one have any expeirance with this meter?

I know this will sound crazy but we cannot get any of the Hanna tri meters to calibrate with the 1413. Use the 1500. I know this sounds crazy, and I don't know why it is this way but it is. I cannot even get the meters to read the 1413 solution properly when calibrated. There are two scales that are used to measure ppm. I think it may have to do something with this...i am not sure how.

Here is some info: http://www.getbluelab.com/Support/Un...le+to+use.html

I had this problem as well with my hanna meter. I messed with it though and on mine their was a setting to adjust the multiplier from ec to ppm. I'm really high and probably a little drunk so I can't remember exactly what it was called. I switched it from like .7 to .5 or something then the calibration solution I had worked fine. Don't know if that helps at all or not.
