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

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

Great Video how can I downdload for teching I´m a biologist from Lima-Perú waiting for your answer Thank you so much!

I would like to know how to use the DR 900 analyzer to measure pH and dissolved oxygen
Hello, you can download our document on dissolved oxygen here: bit.ly/3cTEsSc and pH here: bit.ly/31Pjr52
Make a video how to test TDS please sir
Does it mater which side the pH electrode left or right on the Hq 440
Can I use buffer pH 4 solution for short time storage?
