This module consists of a pH node and a temperature node and can be used to measure either pH or temperature or both and when used together, the pH is automatically temperature compensated.  The functionality of the temperature node is exactly the same as the independent Temperature Node (2101021). The pH node can measure pH values from 0-14, has a 2 point user calibration and can read to better than 0.1pH accuracy, dependant upon calibration. The pH reading can be viewed on the Atlas Base and also the full pH value history can be downloaded to a USB memory stick in csv format.

The pH and Temperature Node can be clipped onto the Support Rods (2101009) and plugs into the Triple Node Socket (2101024). pH Probe and Swivel Adaptor (2200029) plugs into the pH node and RTDs plug into the temperature node.
