No, you can not calibrate it. You can determine a "correction factor" for it. the one you show is good for ball park O2. Dwyers Instruments has already done that for their low end Flow Meters (there low end flow meters are 10 time more accurate than the onew you show) the RMA Series. But still they are not as accurate as the bottle method. Now they do have some electronic flow meters that can be calibrate for HHO. But your talking big$$$
