Heritage® Digital PSG permits up to 36 channels, single- or dual-bed, lab-based PSG Recorder & Reviewer.

The Albert Grass Heritage PSG continues the line of "gold standard" PSG recording systems for which Grass is famous. Each channel has a dedicated amplifier — each completely software configurable with independent control of gain, and filters. The electrode selector allows "on-the-fly" re-referencing of electrodes.
