Which microphone is recommended for low frequency measurements?

Low frequency is a relative term. Standard 1/2" condenser test and measurement grade microphones have a -3 dB point of 1 Hz to 3 Hz, which is sufficient for most applications. Specialty microphones have been developed to exceed that and measure as low as 0.1 Hz.
