Liquid Solutions
Hamilton is one of the few sensor providers to make all of our own liquid calibration standards, buffers, and electrolytes in-house. These products are specifically designed to work with our sensor products lines and ensure the highest quality measurement along with full traceability of the reference material during future calibration or maintenance work.

How often do Incyte sensors (pre-amp version) need to be calibrated?
Hamilton recommends once per year with a validation at 6 months. -
Which liquid conductivity standard should I use for calibration?
A conductivity standard should be chosen that most closely matches the anticipated conductivity range of the process. -
What can I use to clean the conductivity sensor electrodes if fouling occurs?
The metal electrodes of 2 and 4-pole sensors can be cleaned with water and mild detergents and washed with deionized water after cleaning. Care should be taken to not use cleaning agents that can impact the material of the electrodes. Click to reference the knowledgebase article on cleaning for more information.
