200-Watt Modular X-Ray Power

Handheld Long-Wave UV Radiometer: The DM-365X from Spectroline® measures long-wave UV (320-400 nm) with accuracy of better than ±5%, traceable to NIST standards over its measurement range of 0-19,990 pW/cm2. The autozeroing feature eliminates the need for zero adjustment during calibration or use. The meter is calibrated by pyroelectric methods for maximum precision, with good linearity and cosine response. An interference filter controls spectral coverage, and only one intensity reading is necessary to obtain true values. Circle No. 64 on Reader Service Card.

Supplies: Series XMA power supplies from Universal Voltronics are designed for applications requiring stable, low-ripple voltages up to 60 kV, with a 30 kHz filament voltage output of 3-12 volts. Available in 16 models, the units offer flexible control via a 25-pin I/O connector that permits analog control of tube and filament voltage, remote cathode voltage, emission current, and filament current monitoring, and filament idle. Circle No. 63 on Reader Service Card. Scanning Probe Microscope System:

Temperature-Sensing Analytical B a l a n c e : The Alliance/OHAUS® Explorer™ from Alliance Scale features an internal calibration system that senses changes in ambient temperature and indicates when to calibrate. Users can select weighing modes, stability levels, and filters and then read the results on an LCD display. Weighing modes include grams, milligrams, and ounces, and an audit trail can be generated for ISO-9000 requirements. Features include auto-zero tracking, RS232 bidirectional interface, spill gutter, and removable draft shields. Circle No. 72 on Reader Service Card.

Rotary Vane Vacuum Pumps: PreVac's lubricated RV vacuum pumps feature 25% fewer moving parts than competitive pumps for reduced downtime and easier maintenance. The series includes nine lubricated RV pumps in two models: the PH series for vacuum applications down to 0.5 torr, and the PR series down to 10 torr. Both offer a performance range of 4-185 ftVmin and horsepower range of 0.5-10 HP. Pump motors are direct drive 1750 RPM, available in single- or three-phase versions. A cooling shroud is included, which lowers operating temperatures. Circle No. 61 on Reader Service Card. Digital Pulse Generator: Merchantek

Electro-Optics' Model 9318 is an eightchannel, eight-output digital pulse generator for end-use and OEM applications such as control and testing of YAG and excimer lasers and high-speed motion and stop-action imaging. The microprocessor-controlled unit can synchronize up to eight instruments simultaneously. An extended feature provides divide-by-n function for four channels, enabling the instrument to generate pulses at a submultiple of the fundamental frequency. Users can select the delay and pulsewidth for each channel from 1 }is to 99 s. Circle No. 69 on Reader Service Card. 30
