Amplifier portfolio for ALL Unisense microsensors

The UniAmp range of innovative amplifier solutions provide new unique features and a full new level of user friendliness and performance. The fx-6, fx-3 and x-5 systems comes with open channel configuration and provide you our most flexible solutions and meet your needs today and for future applications.

Unique features:

  • Temperature compensation of sensor data
  • E2PROM recognition of unique sensor data
  • USB-powered
  • fx-6 UniAmp with support for ALL Unisense Microsensors
  • Ease-of-use, Simple and Smart!

The amplifiers are USB powered and sensors are immediately polarized when connected. Windows service app initiate automatically when PC connected and allows for fast review of raw data and amplifier settings. Calibration and data logging are done via our SensorTrace Suite apps.

UniAmp comes in various configurations with channels for amperometric sensors (O2, NO, H2, H2S, N2O) and for potentiometric sensors (pH and Redox) and for optical oxygen (OPTO) sensors. All versions include one channel for a temperature sensor needed for temperature compensation of data.

OPTO channel

The fx-6 and fx-3 UniAmp include an optical channel for our OPTO sensors. This gives you the most flexibility and provide choice of amperometric oxygen or optical oxygen dependent on your given application and therefore the best of both worlds. With the fx-6 UniAmp Unisense offers you the only solution available for all microsensor technologies in one unit!

E2PROM sensor connectors

The new 10 pin E2PROM sensor connector brings a new level of user friendliness and performance. Each sensor stores important information about sensor type, sensor customizations, serial number, calibration data, and the unique value for individual temperature compensation. User calibration can also be stored on the E2PROM, saving time during setup and giving ultimate flexibility in using multiple sensors and amplifiers. All E2PROM information is read by the UniAmp ensuring correct sensor polarization and setup, and data are transferred to our SensorTrace Suite software for enhanced user experience and experimental documentation.

The new connector format allows for support of our specialized sensors like the STOX sensor for measuring ultra-low (<5nM) oxygen.

Temperature compensation

Sensor temperature compensation has so far been reserved to optical sensors but using long-time in-house data we now introduce temperature compensation for most of our microsensors.

The compensation covers +/- 3°C from calibration point and thus ensuring you better data. With a standard sensor coefficient of 2-3% per degree Celsius, small sample temperature changes for calibration point of a few degrees will result in considerable errors. With our new temperature compensation algorithm the system will now compensate and ensure more accurate data.

Each sensor comes with a factory value for temperature compensation, but you have the option of measuring your own value for the sensor and apply your  self determined value.
