Razorbill Instruments MP240 Low-Noise High-Isolation Coaxial Multiplexer

The Razorbill Instruments MP240 is a fully shielded, low-noise coaxial multiplexer designed for high-impedance measurement systems. Its double-pole, four-throw configuration allows one common input pair to be switched between four output pairs.

The MP240 is designed for applications involving multiple capacitive sensors, capacitance bridges and stress or strain measurement systems. It can be controlled through USB using the manufacturer’s software or ASCII commands, or through its 5 V digital input. The digital input is compatible with Andeen-Hagerling capacitance bridges.

This unit is New – Open Box and appears unused. The packaging was opened for inspection and photography. It has not been operationally tested by LabCycle Partners.
