Can you use it to measure air mass? Like kg / hour? And does it compensate for air temperature and air pressure?

It measures air velocity, period. Does not compensate for pressure or temperature. Does not measure air mass flow directly.

Can it calculate or convert to Feet per minute?

Here are the specs you are looking for: Measuring range: 0 to 6,000 fpm Accuracy: ±(20 fpm +5 % of m.v.) (0 to 394 fpm) / ±(59 fpm +5 % of m.v.) (394 to +3,000 fpm) Resolution: 1.97 fpm Volume flow: (cfm) 0 to 99,999 cfm (Resolution: 0.1 cfm)

Can you use it to measure the delta?

There's a trendline function that can keep track of changing temp over time.
