Connect all sensors
- 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!
UniAmp Multi Channel is available with channels for amperometric sensors (O2, NO, H2, H2S, N2O), 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. When you connect the sensors, they will immediately polarize.
The amplifiers are USB powered. Connect the UniAmp Multi Channel to your PC to automatically initiate the Windows service app. In the app, you can quickly review raw data and amplifier settings. You can calibrate and log data via our SensorTrace Suite apps.
Temperature compensation
Sensor temperature compensation is available for our O2, N2O, H2, and H2S microsensors. The compensation covers +/- 3°C from calibration point to ensure the quality of your data.
With a standard sensor coefficient of 2-3% per degree Celsius, small sample temperature changes from calibration point of a few degrees will result in considerable errors. With our temperature compensation algorithm, the system will compensate and ensure more accurate data.
Each sensor comes with a factory value for temperature compensation, but you can measure and apply your own value for the sensor.
OPTO channel
The fx-6 and fx-3 UniAmp Multi Channel include an optical channel for our OPTO sensors. This gives you the most flexibility, as you can choose amperometric oxygen or optical oxygen depending on your given application. With the fx-6 UniAmp, Unisense offers you the only solution available for all microsensor technologies in one unit.
E2PROM sensor connectors
The 10 pin E2PROM sensor connector can read 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 to save time during setup and provide flexibility for using multiple sensors and amplifiers. All E2PROM information is read by the UniAmp ensuring correct sensor polarization and setup. 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.
