Analog temperature probe and digital temperature probe in ExBox2, which one?

[Clark song]

I have a P3ex's own analog temperature probe. recently bought an ExBox2 and digital temperature probe. Now the problem has arisen. after I connect everything. I found that my digital probe and analog probe showed inconsistent readings. Then, I put them in the measuring cup of the same ice-water mixture. The result is 10.3 degrees Celsius for the analog probe and 6.3 degrees Celsius for the digital probe, which the gap is 4 degrees Celsius. However, in the sea at 27 degrees Celsius, the gap is almost 0.6 degrees Celsius. Since my conductivity probe relies on temperature compensation to be accurate, I have to choose an accurate temperature probe. So, which temperature probe should I trust? The analog probe or digital probe. By the way, according to 677/319, I calibrated the analog probe. I did not calibrated the digital probe since the lack of calibration data.

Please help guide. Thank you!
