AEMC Instruments 2156.20 - SL20 Single Channel 4-20mA DC Current Data Logger


The AEMC Instruments Model SL20 Simple Logger® is a small one channel recording device powered by two AA alkaline batteries. It can also be powered by 5V using the USB interface cable supplied. The input is 4 - 20 mADC facilitated by two screw terminals. Sample rate is 16/sec with a storage rate of once per second of the average of all the samples. Application software is included with the unit by plugging it into your computer using the USB cable and downloading it from our web site. Scaling units of measure and recording length can be set through the software. Real-time graphs can be displayed, downloaded data can be analyzed, and reports printed.

The main advantage of the SL20 data logger is its ability to begin recording with only the need to configure the length of time for the recording. A simple one button operation is all you need. The front panel LED alerts the operator of the logger’s status.
