The TetrAMM is a high precision 4-channel picoammeter engineered for fast and reliable low current measurements in advanced research and detector applications. Designed for demanding laboratory and beamline environments, the system delivers simultaneous 24-bit sampling at speeds up to 100 kHz per channel. Its integrated bias voltage source, high speed Ethernet connectivity, and real time onboard processing make it an ideal solution for applications requiring accurate multi channel current monitoring and detector biasing.
