Operation range of -75 to +20°Cdp (-103 to
+68°Fdp) suiting the vast majority of calibration
requirements
• Simple operation through manual fl ow mixing
• Flexibility in generating precise target dew-point
temperature
• Generated output responds quickly to a change of
set point
• Stable humidity generation
