2 Pen Portable Strip Chart Recorder


This instrument is an AC powered portable strip chart recorder. The input spans are push button-selectable from eight calibrated ranges of 10 mV to 50 V. The pull-switch attenuator concentric with the ZERO control provides additional four ranges from 20 mV to 100 V using range vernier.

The screwdriver-adjustable VAR control offers continuously variable spans up to 100 V. The 50 mV calibrator is also conveniently used for quick span calibration, eliminating the need to connect an external standard calibrator. The chart speed is selectable from 24 ranges of 48 cm/min to 0.5 cm/hr and the rear panel CHART DRIVE jack gives an external chart speed control capability with external pulse train.

Includes 1-Red Pen, 1-Black Pen and 1-Roll of chart paper, at no additional charge.
