The head of our micrographics unit says:

    "We have two Houston Fearless Extek 4004 Densitometers.  They
    seem to work very well, and offer dependable calibration with
    little operator intervention.  We had a 4010 Densitometer (HF
    Extex) that I would not recommend.  Apparently the factory has
    had a lot of problems with this model."
