This line of instruments is based on a proven, robust and reliable design that is recognized

world-wide as being the standard in recording. Both models have differential inputs with

constant impedance over all input ranges which allow for accurate measurements from

almost any source.

The high sensitivity (up to 400 μV full scale) and gilded input contacts allow even very low

voltages to be measured accurately. The high-speed servo system records signals

An auto pen up at power off to prevents ink stains on paper. The newly designed

penholder has improved grip and simplifies the exchange of pens.
