The HOBO MX2501 can be deployed in several ways.
This video resouce will show you how to easily change out the electrode on your pH logger.
The HOBO MX2501 pH logger calibration procedure is only designed to work with National Bureau of Standards (NBS) pH buffers 4.01, 7.00, and 10.00.
The HOBO MX2501 pH logger's battery-saving water-detect feature is only guaranteed to work in water with at least 100 µS/cm conductivity.
Step 1. Set up a HOBOlink account if you do not have one already.
The Total Hydrogen Scale (pHT) requires custom buffers that are designed to mimic the activity of hydrogen ions in seawater.
