OMEGA Engineering, Inc. Portable Low Cost Data Logger OM-PL

The OM-PL Series data loggers are versatile devices that can be used for a wide range of logging applications. Each data logger is capable of sampling data as fast as once per second or as slow as once every 18 hours. The data logger can stop recording when memory becomes full, or rollover for continuous recording. The start of recording is software selectable to be immediate, delayed, or initiated when the datalogger door is closed. The data loggers can also be used to monitor high and low alarm events, that indicate if the recorded data passed above and/or below the user selected threshold. The alarm events are stored separately from the data samples and are not affected by data rollover. When the recorded data passes the high or the low alarm threshold, the data logger records the time of the alarm. When the recorded data returns to within the acceptable range, the data logger records the duration of the alarm. Up to 50 such alarm events can be recorded. The datalogger has a visual indication of an alarm condition without the need to connect to the computer. The data loggers have an internal real time clock/calendar. This real time clock is used to record the time stamps for data samples and alarm events. This real time clock is independent of your computer clock, and can be set separately, or set to match your computer clock. The data loggers provide a high level of data security. They have physical security, where the data access door is locked, and software security. It is virtually impossible to falsify the sample data or alarm information of the OM-PL Series dataloggers. The data loggers are extremely low power. Under normal operating conditions, a 9 volt alkaline battery will last from 18 months to 2 years.
