Key features

  • Pen offset compensation (optional)
  • Electrical pen lifts
  • RS-232 Serial data output for both channels

The unit also has remote control compatibility and serial data output on all channels via the built-in RS232 serial data port. In addition to the standard voltage inputs, optional input modules are available. These just plug into the BD11E safety banana input and are available for monitoring Temperatures (J, K types), Current and High Voltage are 0-20mA, 4-20mA, 0-16A and up to 500VDC with 10x or 100x attenuation.

The high sensitivity (up to 400 micro Volt full scale) and gilded input contacts allow even very low voltages to be measured accurately, making this the ideal laboratory tool for pH or temperature measurements. The robust and reliable design makes this first choice in teaching laboratories at universities and colleges around the world.

Pen Offset Compensation, which can be built in as an option when ordering the high-speed servo system, records signals up to 5 Hz and the 6th order 14 Hz low pass filter eliminates the 50/60 Hz noise completely for noisy industrial applications.
