Test strips for coolant

[RocketScott]

I use the Baldwin test strips

Can't say if they're better or worse than anything else

Still running green coolant in my 444xt. I test it pretty regularly and add DCA if needed. The filter has DCAs in it and maintains the levels

Because the test strips have an expiration date you might as well test it frequently. With 50 test strips in the kit and an expiration date of a few years you can test once a month and still not use them all up by the time they expire
