The Model 5A-1MP Laboratory Reference Psychrometer provides extremely accurate measurements of relative humidity, dew point, and air temperature. The 5A-1MP is portable, needs no special installation, is simple to use, reliable, and requires very little service to maintain its high accuracy over a long period of time. When properly maintained and utilized, the psychrometer’s accuracy can exceed that of any other type of hygrometer in most humidity measuring situations. The 5A-1MP attains its highest accuracy and is superior to all other hygrometers near saturation.

The 5A-1MP Laboratory Reference Psychrometer may be used for quick and easy measurements in environmentally controlled rooms, environmental test chambers, and manufacturing areas where humidity sensitive products and materials are produced, etc..
