Solução miniaturizada para monitoramento contínuo de H2S/CH2

Cairsens® H₂S / CH₄S

O Cairsens® permite a medição de contaminantes específicos comparáveis aos métodos de referência. Sensores de alta qualidade são reconhecidos mundialmente por nossos clientes que buscam as mais recentes tecnologias em monitoramento da qualidade do ar.

Eles oferecem medições precisas e confiáveis, são calibrados usando um valor de referência padrão. São fornecidos com um certificado de calibração único e não necessitam de calibrações adicionais após a instalação e durante o seu ciclo de vida (a partir de 12 meses).

Excelente precisão de medição é alcançada limitando o efeito da interferência de umidade usando um filtro de entrada dedicado exclusivo combinado com amostragem dinâmica.
