Used this only a couple of times. But it seems to work great. Nice case for storing and being able to use the pump only when testing is nice.
A great investment for heating.

Seems to work fine. The O2 sensor indicator is not present on the display of the new unit purchased in January of 2016. When I called Fieldpiece I was told that there had been some sort of programming revision that affected units built around the time mine was made (June 2014), and the only way to tell when the O2 sensor is needing replacement is to note the % O2 at startup and when it drops below 20.9 its time to replace. I asked what the life expectancy might be for this sensor and was told it would be from two to three years from date of manufacture--not from date put into service. Sounds like I have between 6 months and 18 months of life left in this rather expensive sensor. I was told that (if I should be so lucky) the sensor would fail during the warranty period at which time I could send the unit in for a possible replacement sensor! How about stepping up and selling my new unit with a new sensor???
