About this product
System consists of a humidity/temp indicator w/digital display and humidity/temp probe; probe connected to display by wire; dew point temp 0 deg c to 40 deg c below ambient temp;outputs: dewpoint temp 0 to 1 volt for -40 to 60 deg c, ambient temp 0 to 1 volt for -40 to 60 deg c, relative humidity 0 to 1 volt for 0 to 100 percent rh;measurement of air dewpoint achieved by opto-electronic detection of dew formed on an electrically cooled, solid gold mirror, the temp of mirror is continually monitored and when dew forms the temp is stored in memory; probe houses the dew forming mirror and optics, also carries another transducer for measuring ambient temp; operates and displays continuously while cycling through dewpoint determination every 1/2 to 2 minutes;item will be used to maintain accuracy of the following systems-t.O. 33k6-4-2024-1, p/n 31061222-001, t.O. 33k5-4-84-1 p/n's ct428-7, rh200, htab176
