Analizador de gases láser in situ (TDLS)

LAS 5000XD

El analizador de gas in situ TDLS ha sido diseñado para cumplir con los requisitos de una amplia gama de CEMS y aplicaciones de procesos.

El LAS 5000XD utiliza espectroscopia láser de diodo sintonizable (TDLS) y está disponible en varias versiones para medir parámetros como NH3 + H2O, HF, CO + CO2, O2, HCl + H2O, etc.
Combina robustez, tiempos de respuesta rápidos (1 s) y alta precisión de medición en entornos difíciles (certificación para la versión ATEX en curso).

Las principales ventajas para el usuario del analizador de gases láser in situ LAS 5000XD:

  • No se requiere un sistema de muestreo
  • Sin alteración de la temperatura del gas
  • Sin interferencias de la matriz gaseosa.
  • Medición sin calibración

Gracias a la función ClearPath se elimina la interferencia de la humedad relativa, O2 o CO2 en la zona de soplado.

    KEY FEATURES

  • New Embedded ClearPath functionality
  • Highly sensitive and selective measurement
  • High signal-to-noise ratio
  • No measurement drift
  • Response time 1 s
  • Large dynamic range from ppm to %
  • Real-time communication between Transmitter (Tx) and Receiver (Rx)
  • Robust, ready for Ex Zone II (certification to come)
    💡 CLEARPATH

  • Interference of relative humidity, O2 or CO2 is removed in purging areas.
    Operator’s benefits:

  • No need for N2 or dry air purge
  • High accuracy of O2 measurement
  • High accuracy of H2O measurement
