Had my Analox O2EII for about 4 years. I have the saver plug on when not in use. It gets used about 25 days a year. Still can make adjustment to 21 percent when testing air and can still dial it up 26.5. How do i know when it is time to replace. When i can no longer calibrate to 21?
Who makes a good replacement?
Can I get another trip out of it in 2 weeks or should I replace just based on age?
Thanks,
Al
