Medición de ultratrazas de mercurio total en forma gaseosa


El sistema Ultratracer (UT) mide el mercurio total en forma gaseosa (TGM) en el aire u otros gases (ng, por ejemplo). Compacto y fiable para mediciones de trazas (subng/m3) según EN 15852

El UT-3000 funciona automáticamente. Todas las funciones están controladas por un microprocesador incorporado. Cuando se toman las mediciones, todos los parámetros y resultados se almacenan en el registrador de datos integrado.

Con la configuración estándar, el registrador de datos tiene una capacidad de registro de 4 semanas.

  • Offers sensitivity and detection limits far superior to other mercury analyzers on the market using similar technologies

  • Insensitive to interferences caused by the quenching effect
  • Automatic Operation
  • Automatic sample flow control
  • AutoRange function
  • Manual or automatic calibration modules (optional accessories)
  • Integrated data logger for more than 5000 measurements
  • Multiplexer operation (option)
  • Special version UT-3000 NG mobile (option) – all in one system for mercury measurements in natural gas
  • Continuous outdoor and indoor air quality monitoring
  • Stationary and mobile AQMS laboratories
  • Industrial fence-line and field monitoring
  • Environmental pollution source tracking
  • Studies of mercury dispersion in the atmosphere
  • Natural gas and derivatives
  • Emission monitoring
