Time series from a SeaFET V2 pH sensor

Classic Tech Tip – Offset pH Data

Take a look at the figure on the left- it contains pH data from a recently calibrated SeaFET sensor deployed in a stable environment. Samples measured by a spectrophotometer are superimposed over the SeaFET data to help validate the sensor’s performance.

At first glance, pH in the highlighted section appears to be unstable and well out of spec. Can you identify what is wrong with this data?

This question was originally published in our June 2018 Newsletter.
