Product outline

AM32AZ is a general-purpose DC amplifier with a built-in bridge excitation supply for strain gauge sensors. It exhibits power performance for broadband operation (DC -100 kHz) achieving high gain (Max. gain: 10000 times), but it has an extremely low drift. Therefore, data precision with every measurement or experiment markedly improves. In addition, AM32AZ has excellent user-friendliness. It is equipped with a calibration function by digital switch which allows easy calibration of either value of voltage or strain amount.
