MicroLite USB 4-20 mA Current Logger

MicroLite USB 4-20 mA Current Logger

Inquiry Catalog


This MicroLite logger measures current over a range of 4 to 20 mA, with accuracy of ±20 µA. Offering a 32,000 sample cyclic memory, the MicroLite Current logger features a USB interface for easy connection to a PC for user configuration, data download and sensor calibration using the free Windows-based DataSuite data analysis software.

The logger's external input includes two screw terminals for easy wire-up, with scalable units supported by the software and device LCD. You can setup low and high alarm thresholds and view the logger data on the 4-digit LCD, which scrolls between the current and minimum/maximum readings. The LED provides additional sample and alarm indication in the event the LCD is off due to the MicroLite's power save mode.

The logger is designed for both portable and stationary multi-use operation with a replaceable 3V coin battery lasting up to 1.5 years, depending on the operating conditions.


Together with the DataSuite software the MicroLite External Temp logger is also 21 CFR Part 11 compliant.
