Application is oil furnace air/fuel ratio tune up.
It's not going to get a lot of use. so would like one that doesn't need to be recalibrated frequently.

Had the old plastic dumbbell type with red liquid but it cracked.

    Digital is probably the best way to go. But "Westwood Products" has the old wet kits in their catalog. Don't know the cost. I am sure your oil burner supply house could get you a price

    Someone once told me the wet kits were similar to using a clock without a minute hand.

    At that point I decided I couldn't afford a decent combustion analyzer and looked into renting one.

    Hey Leonard,
    For everyday use, there are several excellent digital instruments out there. But most use some type of O2 sensor which must be replaced periodically.
    The O2 sensors are not inexpensive and typically have a 2 year warranty from date of manufacture. In other words, they have a finite 2 year service life whether in use, in the case or on the shelf.
    In addition most manufacturers recommend or require periodic factory calibration. Maybe not the best choice for an occasional use situation.
    For occasional use, the good old wet kit may be the way to go.
    Kinda Flintstone by today’s digital standards, but retro is Cool!
    Best..
