The Basics of pH Measurement - Hach Educational Video

[@richhughes2225]

This is a very good training video. It would be helpful to include information regarding measurement issues associated with low ionic strength solutions.

+Rich Hughes Thanks for the feedback, we'll keep that in mind for next time.

Does it mater which side the pH electrode left or right on the Hq 440

Hi. Is this equipment suitable for chloride measurement?? Actualy i have to do chloride analysis by potentiometry. Is this suitable for mv reading corresponds to the chloride concentration.

Great Video..... My new ph probe just stopped working properly after about 2 months of continuous use. I keep getting slope erros. DO I need to replace? I tried cleaning with soap solution but still slope error (percentage in the 80's. SHould I re adjust the percentage limit to 80-120? right now its 85-100 and its rejecting when i calibrate.

I would like to know how to use the DR 900 analyzer to measure pH and dissolved oxygen

Make a video how to test TDS please sir

Can I use buffer pH 4 solution for short time storage?

[@hachcompany]

Hello Nina, thank you for asking! Hach pH probes should not be stored in anything other than the designated storage solution at any time. For storage between measurements taken a few minutes apart it is acceptable to pour some storage solution into a small beaker temporarily. You can see the correct storage solutions here: bit.ly/3r0ZRjA
