I was ready to purchase a Testo327,,now I see they have new ones. Testo 310,320. Has anybody used one,or Ideas on any others? I do residential mainly. Thanks ahead.
I use my combustion analyzer or I have a Fluke CO-220.
I have the fieldpiece co detector. Been pretty happy with it
I have the 327 and am happy with it. I wish it responded more quickly but i was interested in the 320 if anyone can chime in the 327 vs 320.
I thought the 327 was very vast
