We are getting a Anton Parr co2/o2 meter. My filter has a sample valve that attaches with a DIN fitting and I will not be able to attach the clamp of the unit onto it. So looking for a perlick style valve. I know I can put one further down the line with a TC fitting, but the area where the sample valve is at on my filter is a really good place to check for O2
