Audio impedance meter and sound level meter

• The SC-102 from Promax, not only performs the measurements, but also performs the checks and calculations required by the rules to obtain a final result. It is the first integrating sound level meter with measurement protocols which simplifies the process to obtain the results. Guides the user step by step in performing measurements.
• The MP-003 (MPI-3) is an impedance meter working at a frequency of 1 kHz which, in addition, enables knowing the resistance in DC and the minimum power required by an amplifier to attack this impedance.
