- Easy-to-use, simple, and smart
UniAmp Single Channel is available in various configurations with dedicated channels for O2, pH/mV, H2, N2O, or H2S. All versions include one channel for a temperature sensor for temperature compensation of data.
The amplifier is USB powered, and the sensors immediately polarize when connected. Connect the UniAmp 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 was once reserved for optical sensors. However, based on long-time in-house data temperature compensation is available for our O2, N2O, H2, and H2S microsensors.
The compensation covers +/- 3°C from calibration point, thus ensuring you better 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 your own value for the sensor and apply this value.
E2PROM sensor connectors
The 10 pin E2PROM sensor connector reads 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 concentrations.
