概述

Welcome to the future of mass spectrometer-based helium leak detection. Weighing 17 lbs., the PICO is truly the smallest mass spectrometer-based leak detector available in the world today. Incorporating advanced technology in mass spectrometry and vacuum technology (patents pending), the PICO provides fast, contamination-free, leak detection. As a vacuum style helium leak detector, the PICO can be quickly and easily transported to the vacuum system to be leak tested without the need for bulky transport carts. In addition to an ion trap mass spectrometer, the PICO has an integral vacuum system which incorporates a turbomolecular pump as well as a backing scroll pump. Aided by the small volumes of the unit, the PICO has a very fast response and clean-up time. The PICO incorporates a removable handheld remote display with 15 ft. of interconnecting cable. The user interface is self-intuitive and very simple to use. The helium leak rate is displayed in numeric, bar graph, and historical trending formats. The remote display also incorporates an audio alarm which can be heard in very noisy environments, often encountered in leak detection applications. The PICO also includes self-protection circuitry that protects the integral turbomolecular pump from situations which would normally damage the turbo pump and require significant repair. The unit also includes a "zero" feature that compensates for background levels of helium often encountered in leak detection applications.
