This will require a little bit long intro.
I came across your forum in the search for pool testers.
We have a "public pool" in the sense that we share it 10 apartments, and we are therefore required to measure our pool twice a day and have uannounced measurements by a professional company made approximately every month.
We expect to be 3-4 different people doing the tests, and the general opinion was that we would definitely prefer something digital. However we are also interested in the most userfriendly procedure which isn't too time-consuming.
We have just had installed (1 week ago) an Autodos M2 system which measures and controls the pH and chlorine levels. pH is adjusted with sulfuric acid added automatically as it goes off from the set-point (currently 7.25). Chlorine is added with a Pentair Intellichlor IC40 SWG, when CL level is below the setpoint.
We have until now managed checking the pH and free chlorine levels with a CheckIt Trutest digital strip tester. Browsing the internet, it seems that it is considered useless and very inaccurate. To us it has however seemed very quick and convenient to use.
Now we however need something a bit more accurate for daily measurements which can also measure total chlorine. Also our Autodos system's chlorine levels must be calibrated regularly.
I have seen that many here are fond of TF100 test kits and Taylor K-2006. But since we generally wish to find a digital solution, I would prefer if we could find something that suits that purpose. Also I live in Denmark / Europe and therefore doesn't have the same items available as you.
The testers I have stumpled upon are:
LaMotte ColorQ Pro 7 - this seemed like it received positive comments, although many users also experienced their measurements to be inconsistens or inaccurate compared to TF100 tests.
This will cost us approximately 2200 DKR. incl. reagents - appr. $360.
It seems OK efficient compared to other photometers.
Lovibond Scuba CL/pH/CY small handheld device also requiring powder pills.
Will cost us approximately 6-700 DKR - approximately $100-120.

Lovibond MD200 Checkit Direct
I have seen a YouTube video of this and it seems simple, although not very efficient to do measurements with. Also this is rather expensive even though we may get a good price from our distributor.
I estimate the cost to be approximately 2-2500 DKR - appr. $400.
Are you familiar with any of the Lovibonds? Or can you recommend anything similar for easy, daily measurements?
If we choose such a solution, is it generally recommended to go for liquid reagents or tablets?
Thanks in advance!
