The MSR 145S is a miniaturized universal data logger for measuring and recording different physical measurement parameters. It contains an internal temperature sensor, a humidity sensor, a pressure sensor, a 3-axis accelerometer (X, Y and Z axes) and new to the range a light sensor. Additionally we have a dual analogue input option for other sensors.
The measurement parameters are stored in its large internal memory and can be downloaded to your PC in a matter of seconds through the high speed USB port. The internal battery automatically charges while the data logger is connected to your PC.

Storage Rate: Temperature and Humidity: once a second to every 12 hours. Pressure: 10Hz to every 12 hours. Acceleration: 50Hz to every 12 hours. Light: 1Hz to every 12 hours. PC Software
The integrated software in each unit includes Free Setup, Reader, Viewer and Online software (Windows 95 or higher) to record and evaluate data. All measurement parameters can be rapidly transferred to a PC via the USB connection both during the measurement operation and once the measurement task has been completed. Each unit includes an integrated clock (RTC), allowing data from as many MSR 145 units as required to be synchronised and merged into a single data record.
