Flexible Resolution Digitizer

The PXI-5922 from National Instruments, Austin, TX, is a flexible resolution digitizer that, combined with LabVIEW 7.1, can be used to create various instruments, such as AC voltmeters, audio analyzers, frequency counters, spectrum analyzers, or I/Q modulation analyzers. The device uses the company's FlexII ADC which features flexible resolution and can sample from 16 bits at 15 Msps to 24 bits at 500 Ksps. The module allows you to directly digitize low-level signals without the need for external signal conditioning. (800-258-7022, [email protected],

Air Monitoring System

The UV Hound from Ocean Optics, Inc., Dunedin, FL, is a portable point sampling air monitor that uses UV absorbance to identify up to twenty toxic airborne compounds at concentrations as low as ppb. The device is built around the company's HR2000 high-resolution spectrometer. It works by drawing ambient air through the system's intake vent and passing it through an optical analysis chamber before expelling it. Windows-based software lets you perform compound selection, continuous automated monitoring display, and data logging. (727-733-2447, [email protected],

Thermal Flow Sensor
