Self-Balancing ? Low Battery Power Consumption The EPR series of portable chart recorders are designed to provide high performance chart recording functions in the field environment. Features Excellent Suitability for Field Use Due to its compact size and light weight, this recorder is very easy to transport and operate in field conditions and remote locations. Long Battery Life These recorders have been designed for low power consumption. This doubles the life of the internal batteries in comparison with our conventional recorders (i.e. a single-pen recorder can operate continuously for approx. 40 hours). The recorder has an indicator light showing the battery status. Flexible Chart Paper Handling Both Z ? fold and roll type paper can be used (Optional roll adapter is required for the roll type paper). User Friendly Operation Sensitivity volume adjustment is provided on the front panel to allow easy span calibration. Chart feed button is provided for time axis matching. A Complementary plate is provided to write notes on the chart paper.
