Question
Can a bubble trap be used with the CM130 Chlorine Monitoring System?
Summary
Description of how bubbles interact with the measurement system and how they should and shouldn't be handeled.
Answer

Air bubbles in the sample will lead to issues with the CM130. The symptom of this is most commonly the alarm state "Bubbles Detected." In this alarm state the instrument will remain idle and will no longer display results. 

It is recommended that the biomed check the inlet for visible signs of bubbles when the alarm state is on. If bubbles can be seen then that generally indicates a problem with a another piece of equipment in the water room. Davita should be contacted to perform these troubleshooting steps. If visible bubbles cannot be seen, contact Hach Tech Support.

Hach can not make recommendations on the use of bubble traps with the CM130 Chlorine Monitoring System.
