Power quality monitor

Capturing up to eight channels of input data to an internal hard drive at a fixed sample rate of 6250 Hz, the Dash 8Xe lets you monitor a variety of power events, such as interrupts, swells, sags, harmonics, unbalance, and power factor. It permits harmonic analysis up to the 50^th harmonic, while maximizing the duration of an acquisition stored on the 36-Gbyte hard drive. In transient mode, the Dash 8Xe captures high-speed glitches and other anomalies at a sample rate of 200 kHz per channel. The unit is equipped with a 15-in. monitor with touch-screen control for real-time data viewing and analysis. Base price: $12,000. Astro-Med, www.astro-med.com/power.
