Digital Charged Plate Monitor
A digital charged plate monitor for measuring the performance of air ionization systems and monitoring charge accumulation will be available from Ion Systems and Monroe Electronics beginning in January.
The product, jointly developed by the companies, is programmable for start, stop, charging voltages and duration of test. After these parameters have been established in the charged plate monitor's memory, they can be used at other test locations; a self-contained power system makes the unit portable. It can cycle through a series of tests independent of a user storing the resulting measurement data in the monitor's memory. Data for more than 100 locations can be stored and subsequently downloaded to a personal computer for evaluation. The unit can store information for approximately 1000 tests.
The digital device measures discharge time using contact electrode technology, which provides high accuracy and stability while minimizing voltage drift, according to the manufacturers. It comes with a 6×6-in. plate installed and supports remote monitor plates of various sizes down to 1×1 in. Variable plate sizes can be detached from the body of the system, so the tool can be used in such tight areas as minienvironments.
The monitor will be known as Model 280 CPM from Ion Systems and Model 288 CPM from Monroe Electronics, which is based in Lyndonville, NY.

Liquid Sampling System
 |
Designed for sampling contaminants in hot process chemicals in wet benches, the modular CLS-900 corrosive liquid sampling system consists of Windows-based software and three hardware subsystems. Fluidic modules containing liquid particle counters are dedicated to individual chemical baths to eliminate cross contamination and can be integrated into the wet station, according to the manufacturer. The base control unit synchronizes system sampling with wet station process events and communicates system data over an Ethernet 10Base-T network.

Photoresist Filter
 |
Recommended for low pH antireflective coatings and for deep ultraviolet photoresists, the Falcon PE-Kleen photoresist filter is constructed of high-density polyethylene, enabling spontaneous wettability in solvent-based photoresists. This minimizes photochemical waste by providing quick start-up, minimized bubble generation and consistent performance. The use of a crescent-shaped Ultipleat filter configuration ensures low pressure drop.

Sealed Louver
Vision+ sealed louvers fit all flourescent ceiling troffers to provide glare-free lighting in electronic and pharmaceutical cleanrooms. They yield maximum efficiency at the 0 to 60-degree angles of light output, negating glare. The product's underside is a smooth, clear lens that does not disrupt ambient air flow and filtering in the cleanroom, according to the company. Light fixtures employing the louvers are triple-gasketed against intrusion of dust, moisture and particles.
