Heated Self Compensating Duct Probe

Source: Emerson


The heated Self Compensating Duct Probe (SCDP-H) has been designed for use in temperatures as low as -40 °C. When used with a GDA aspirator, it provides a complete duct sampling system capable of operating in hazardous areas. The SCDP-H allows simple, trouble free, representative sampling of duct environments.
