...for a wide range of real-world physical measurement applications. One primary benefit of using data loggers is the ability to automatically collect data on an hourly and daily basis. Upon activation, data loggers are typically deployed and left unattended to measure and record information for duration of the monitoring period. This allows for a comprehensive, accurate picture of the environmental conditions being monitored, such as temperature, humidity, single and three phase power usage, CO2, mV, mA, voltage, RPM, torque, pulses, or counts. Graphtec Data Loggers, battery powered and being portable, equipped with a microprocessor stores all sensor data to the internal memory for data storage.
