The Microtrak 7000 provides high-resolution measurements, at a wide range of frequency responses, in one ruggedly built instrument. It measures distance, displacement, vibration or thickness without contact - at operating distances of up to 6.0 inches (152.4 mm). The unmatched accuracy is achieved through high-quality optics, the latest microchip technology and advanced digital signal processing. The results are provided on the large LCD alphanumeric display or can be obtained through the rear panel analog or digital outputs. The visible laser beam allows for easy setup and alignment of the sensing heads.
