Hello all,
I am curious if anyone is aware of a scale with high precision that is capable of data logging as well. Though we have found some that may work in a lab setting, we require one that operates in outdoor conditions, thus what we have found (maximum operating temperature at 104F) does not work as we will be recording data during hot periods. Any thoughts? Thanks for the help!

Hi,
Can you clarify what you mean by "does not work"?
If I were to guess, I'd say the firmware temperature compensation tables for the load cell tops out at 40 deg C (104 deg F). Everything else should still function to 70 deg C, which is the most common and most lax rating for electronic components.
If this is the case, then the scale probably still retains precision (output is repeatable) even if it is inaccurate (output is wrong-ish), so it's possible to calibrate it. This could be as simple as tabulating the measured weights of standard weight samples at different temperatures, to adjust the output of your scale in post processing. Unfortunately this means you also need to log the temperature, and you'd want to store the scale at close to ambient temperature so it quickly equilibrates (a good idea regardless) when you need to use it.
