Müller Voltage Amplifier MVA 10
Low Noise Amplifier with 10 MHz Bandwidth
For Thermocouples and Hydrophones

This Amplifier is a reasonable and the ideal product for our MCT Thermocouples. Together with the 1 MHz filter, it has an excellent signal to noise ratio for the small signals of the type E or type K thermocouples.
A second application is together with our Müller-Platte Needle Probe or M60-1. The signal of these hydrophones are quite small in applications like ultrasound.. However, together with the MVA 10 the range of application extends to the complete field of ultrasound. The amplifier will be used with full 10 MHz bandwidth to measure signals in a plane or focused field as well as for sinus or pulsed waves.
Other applications are general preamplifier for oscilloscopes and transient recorders, photomultiplyer, signal booster for optical receivers and current amplifiers.
