I figured this thread would be helpful....

Has anyone experienced "condensation" or "bubbles" errors ? I get them from time to time and end up doing a periodic maint. until the next one. Anyone have a clue to the cause? It is not humid in my water room. I have three clinics with CM130's but only one is doing this. I feel it could be a teammate doing something they shouldn't.

For those of you that have the Hach continuous chlorine monitoring system (CM130 I think), can you tell us your thoughts on this?
1. Is it accurate?
2. What maintenance has to be done to the analyzer and how often?
3. How often do you have to replace the reagents?
4. How often does it sample?
5. Do state surveyors have any issues with them?
Anything else you can think to add would be great. Thank you.
I apologize. This may have been better placed on the water systems and water equipment forum.

1. Is it accurate? So the quality check in the morning is just to verify that your chlorine levels are actually below 0.1 but as long as the monthly maintenance is done it's worked well. Mine usually sits between 0.04-0.06 according to the cm130.
2. What maintenance has to be done to the analyzer and how often? Monthly swap of chemicals and calibrated with a test solution. Semiannual swap of the Chlorimeter and an annual swap of the battery.
3. How often do you have to replace the reagents? Monthly
4. How often does it sample? Every 5 minutes. This data is sent to our chairside computer system that the clinical staff uses. They can see a history of readings as well.
5. Do state surveyors have any issues with them? Mine is still new but our internal surveying teams seem to like them. I think state surveyors are warming up to them as long as you have all the right processes in place. Breakthrough plans, proper labeling, organized area etc.
I will add that my clinical team really likes it, and I was able to remove the 4 hour chlorine documentation all together in my clinic.

Resurrecting an old thread here to add my two cents. In my area we have very few clinics that are using them as a primary means of checking chlorine. Our biggest issues seem to be problems with the maintenance "taking" after we perform it. Sometimes we'll do monthly maintenance and at the end get a "Measurement too high" message and we're forced to repeat the process over. Sometimes we'll finish the maintenance and it will be good to go, then two or three days later we get a "maintenance overdue" message. I've never had an issue with a periodic maintenance, just the monthly. Then there's the issues with bubbles, etc. We've had them for about three or four years now. We've been told to call Hach every time something crazy happens, but I think most of us have given up as they just say something like "flush it with more RO water" or "We're looking into that issue".
We are using them as a secondary check on the chlorine and that made a good impression on a state surveyor when we had a chlorine breakthrough during a survey and the CM-130 caught it. In less than two hours we had portable carbons in place and the team was able to go back to 4 hour checks. The surveyor was impressed with the CM-130 and how fast we handled the breakthrough.

HACH is supposed to release a software fix for the "bubbles" & "condensation" alarm within the next few months is what we've been told at the big D. Something about changing the water sampling rate to a longer time. My go to fix has been to just remove the door and clean out the chlorometer. Remove the T-screws and wipe the inside of the clear "cavity" of the mold/residuals. That's pretty much what sold it for me until the next periodic kit comes in.

Some clinics water just will not permit the use of the CM-130. The readings will be over .15 and there is nothing you can do other than maybe lignite. When you test the water with conventional strips its fine (.03). I think the Aluminum or Magnesium content in the city/well water has alot to do with messing up the readings. If anyone knows anything that helped them for this issue please post. Hach really isn't that much help when you call them...

we had some of the same challenges there are a few options we doubled the carbon in one facility and the other one we added an organic scavenger as our pH was >9 and our TOCs were around 2 so once we got the pH down to 7 and TOCs below 0.2 we see chlorine levels now of 0.00 or 0.01
