Metal tube flowmeter brochure
This brochure describes the MT 3809 through-flow meter, an instrument that features 2% full-scale accuracy and high repeatability, and is capable of handling high temperatures, high pressures, and a broad range of flow capacities. In addition, the MT 3809 is less sensitive to high-viscosity fluids, operates with minimal pressure drop, requires no back pressure, and provides increased damping for gas appli-
cations to eliminate float bounce. The meter is available with a microprocessor-based transmitter, optional alarm and pulse output for totalization, and one or two switch-inductive alarms with or without the transmitter. Brooks Instrument, Hatfield, PA; ph 215/362-3700, fax 215/362-3745.
Cold cathode starter brochure
This brochure highlights the IgniTorr, a device that emits photons at the exact energy required to release electrons from a cathode, providing the means to start and maintain ionization in a cold cathode starter. A cold cathode ionization sensor measures vacuum by the number of positive ions collected in a plasma. The sensor has electrodes with a large electric potential difference and strong magnetic fields. Electrons are created that are accelerated toward the anode, but the magnetic field deflects them, making them travel a longer path before eventually colliding with the anode. Atoms and molecules in the gas are ionized, and positive ions are captured by the ion collector to indicate pressure. The IgniTorr is a double-sided, 2 3/4-in. CF flange with a welded UV transparent glass lamp cover. The lamp cover is positioned on the IgniTorr so that released photons have line-of-sight access to the internal surfaces of the cathode.

Wet processing system brochure
This full-color brochure describes the FPD Full-Flow Wet Processing system designed for the advanced processing of flat panel displays. The system`s Direct Displace chamber design and process approach perform critical cleans and etches with no contamination or watermark formation. Unlike wet benches and in-line sprays, the Direct Displace process keeps the flat panel glass stationary and moves the chemistries through the processing chamber. This approach integrates
all processes, including etch, clean, strip, and dry, in a single chamber, saving costs and floor space, while boosting reliability and throughput. The process results also provide uniformity across the entire flat panel surface. CFM Technologies Inc., West Chester, PA; ph 610/696-8300, fax 610/696-8309.
