K-O Concepts Remote Exhaust Module K-O Concepts "REM" ventilator module is used to exhaust heated air into the air conditioner return or to the outside. The module can also be used to ventilate non-toxic fumes. The optional plenum easily attaches to 19" racks or cabinets to interface with the ventilator module for powerful, quiet removal of waste heat. Modules are 18"x24" panels, easy for installation into a drop ceiling grid or may be installed into a framed ceiling. Powerful motor provides up to 350CFM on high speed or 200CFM for low speed. Quiet and efficient 115VAC motor consumes only 140 watts and weighs only 26 lbs. For more information, see: K-O Concepts Web site.

WAYNE KERR NEW "B" Series of Precision Magnetics Anaylzers 3260B Precision Magnetics Analyzer The new "B" version has standardized several options and added new capabilities. The extended frequency range of 20Hz-3MHz is now standard. A new Telecom Measurement function has been added. This provides Insertion Loss and Return Loss for line matching transformers in the telephone speech band (100Hz-20KHz). Values for line impedance and termination are user selectable. Optional simulated damping network and series blocking capacitor are user configurable. The 3260B also has a Multi-Frequency Mode that allows the user to specify up to 8 specific frequencies and test at these frequencies against preset limits and present the results in a tabular form. All results can be viewed on the high contrast display or output to the centronics interface. In additon the IEE488 interface allows the unit to be controlled automatically. LabVIEW drivers are available on request. The 3260B also performs a search between two user selected frequencies and locates the resonant frequency by identifying the phase shift through 0 degrees. If resonance is not located between the selected frequencies, the user can extrapolate the data to locate resonance up to aproximately 6MHz. 3255B Inductance Analyzer We have extended the standard frequency range to 500KHz from 200KHz. We have also added the multi-frequency mode, allowing the user to choose up to 8 frequencies and applying limits to these frequencies and sweeping them with a tabular output. Resonant frequency calculation is also available on the 3255B. Another added capability of the 3255B is the use with the DC Bias units. For more information, see: Wayne Kerr Web site.
