The Series LCR20 Dual Pen Circular Chart Recorder offers a wide range of features in an easy to use package. The large 10" (254 mm) Circular chart allows easy reading of your data. Available in clockwise and counter clockwise rotation, the LCR20 is compatible with Honeywell and Partlow circular charts. The LCR20 has one pen input that can be easily programmed for any of six different thermocouple types, 100 ohm platinum DIN RTDs, or process inputs (0 to 5 VDC or 4 to 20 mA). Inputs may be scaled to a minimum of 100 units (or degrees) to a maximum of the sensor scale or -1999 to +9999.
