Monitoring Supports Coastal Environmental Impact Study in South Korea

South Korean water management agency utilizes data loggers to investigate coastal water impacts from hydroelectric dam discharges.

I cannot connect to my new HOBO MX logger - or My existing logger says it's out of range.

Refer to the HOBOmobile setting called "Show Only My Devices" (see attached screenshots).

HOBO Water Logger Deployment Considerations - Ask the Experts!

HOBO data logging experts discuss considerations for deploying temperature, conductivity, salinity, dissolved oxygen, and water level loggers in streams, lakes, estuaries, and oceans.

How to get MX logger data to HOBOware through HOBOlink

New! HOBO pH & Temperature Data Logger

An introduction to the Bluetooth-enabled HOBO MX2501 pH & Temperature Data Logger, for long-term monitoring of pH in aquatic environments - with no need for extra equipment or complicated calibration procedures.

Calibrating for pH at Temperatures Other than 25°C

The observed pH of the buffers (and samples) varies depending on temperature.

Using a Three-Point pH Calibration versus a Two-Point pH Calibration

In order to guarantee the accuracy of your readings, it is necessary to bracket the expected pH values with at least two buffers.

Why Do I Always Have to Calibrate in pH 7.00 and Then at Least One Other Buffer?

pH is considered an inferred value. This means that raw data (in this case potential as mV and temperature) are used to calculate pH with a known algorithm called the Nernst Equation.

Wiping the Electrodes Between pH Buffers - Don't Do It!

When calibrating a pH electrode, the user is mitigating the effect of the condition of the electrode, among other factors.
