In Situ UniAmp

Robust sensor signals and ease-of-use

The In Situ UniAmp and Connector System is an integrated part of our Field Systems portfolio including MiniProfiler MP4/8, Field Datalogger Mini, UnderWater Meter, and Deep Sea Lander.

Microsensors are sensitive and extremely accurate measuring tools. To avoid that the minute sensor signals (pA or mV) are influenced by background noise, the amplifier is placed directly on the microsensor. From here, the amplifier converts the sensor signal into a robust voltage signal, which is conducted to the datalogger through a high quality cable. In other words, the In Situ UniAmp functions as a miniaturized pA- or mV-meter and ensures high quality signals.

The In Situ UniAmp is sensor-type specific with built-in polarization of the sensor and amplification of the signal. Any sensor channel on your Field System can, therefore, be connected to any In Situ UniAmp. These amplifiers can easily be interchanged, both within and between instruments, giving you total flexibility for future studies.

In Situ Connector System

The In Situ UniAmp Connector System is designed for mounting the sensor on the amplifier and for easy replacement of sensors while in the field.

  • Protects the sensor tip during handling and preparation
  • Provides pressure compensation at all depth
  • Simple snap-on mounting
  • Improved shielding for very stable signals, both in the lab and in the field
