Try it. :D Just better calibrate it often with whatever stable molecules are used for that and borrowing a known-good, real machine. Maybe record the uncorrecte

Try it. :D Just better calibrate it often with whatever stable molecules are used for that and borrowing a known-good, real machine. Maybe record the uncorrected reading to get the drift (both kinds ;) at each calibration so you know if it's wearing out, eg, needs to be calibrated more often or replaced if it's a PITA.
