PowerLab 4/35 with LabChart Pro

Overview:

The PL3504/P PowerLab 4/35 is a high-performance data acquisition system suitable for a wide range of research applications that require up to 4 input channels. Typical applications include human and animal physiology, pharmacology,neurophysiology, biology, zoology, biochemistry, and biomedical engineering. The unit is capable of recording at speeds of up to 400 000 samples per second continuously to disk (aggregate), and is compatible with instruments, signal conditioners and transducers supplied by ADInstruments, as well as many other brands. In addition to standard single-ended BNC inputs, the PowerLab 4/35 features 4 differential Pod ports that allow for direct connection of Pod signal conditioners and appropriate transducers.

The PowerLab 4/35 is shipped with ADInstruments software (LabChart) and associated manuals and cables. The PL3504/P is also supplied with LabChart Pro Modules software which includes all the ADInstruments LabChart Modules. LabChart Modules provide application specific data acquisition, analysis and display features.

The Modules currently available include:

• Blood Pressure (Windows)
• Cardiac Output (Windows)
• Circadian Analysis (Windows)
• DMT Normalization (Windows & Macintosh)
• Dose Response (Windows)
• ECG Analysis (Windows)
• Heart Rate Variability (Windows & Macintosh)
• Metabolic (Windows & Macintosh)
• Peak Analysis (Windows)
• PV Loop (Windows)
• Spike Histogram (Windows & Macintosh)
• Video Capture (Windows & Macintosh)

Purchasers of LabChart Pro or PowerLab 35 units with LabChart Pro are entitled to 5 years of FREE LabChart Pro software upgrades and updates. Purchasers are also entitled to any ADInstruments modules released during this 5 year period (excludes GLP Client and Server).
