Solución miniaturizada para monitorización continua de O₃ + NO₂

Cairsens® O₃ + NO₂

El Cairsens® permite la medición de contaminantes específicos comparables a los métodos de referencia. Los sensores de alta calidad son reconocidos mundialmente por nuestros clientes que buscan las últimas tecnologías en monitoreo de la calidad del aire.

Ofrecen mediciones precisas y confiables, están calibrados utilizando un valor de referencia estándar. Se suministran con un certificado de calibración único y no requieren otras calibraciones después de la instalación y durante su ciclo de vida (a partir de 12 meses).

Se logra una excelente precisión de medición limitando el efecto de la interferencia de la humedad utilizando un filtro de entrada específico patentado combinado con muestreo dinámico.
