The Ultra-Low Temperature series data logger records temperatures in a broad line of applications such as monitoring blood plasma, vaccines, pharmaceutical, frozen foods and shipping containers.  The LM-XSPro ULT (Ultra Low Temperature) Data logger is an external sensor data logger meeting the requirements of WHO PQS E006/TR06.4. It displays “✔” if the temperature remains within the recommended limits, and an “X” is displayed if the hot or freezing temperature is exceeded for a period of time above the recommended limits. It gives an audio-visual alarm for any violations of temperature. It stores the data up to 120 days and user can see the history data up to last 30 days without downloading or connecting the device to the computer. All the parameters and alarm limits can be configured using software application. Intuitive menus and large display make it easy to use. It comes with individual NABL traceable calibration certificate. Accurate and reliable working makes it the ideal temperature monitoring solution for any application involving ultra low temperature recording.
