Description: Digital Hygro-Thermometer DP989M Protimeter Up for sale is a Digital Hygro-Thermometer manufactured by Protimeter. Item is in used condition. Item shows minimal signs of wear and tear such as scuffs, marks, and adhesive residue. Item was tested and powers on. The screen displays "Multiple Faults" but the probes are not installed nor included. One switch on the back will change the display from Fahrenheit to Celsius. The other switch does not appear to function. Power switch functions as expected. Only what is pictured is included. FeaturesFEATSpecial FeaturesSystem 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, HTAB176FTLDFunctional DescriptionThe protimeter dewpoint meter uses analog and digital electronics to simplify accurate and stable hygrometric measurement; direct measurement of dewpointRTSERelationship to Similar EquipmentReplaces the air force's current temp and humidity transfer standards used in pmel, P/N SA-760-A nsn 6625-01-144-1855 digital readout and P/N H5-3552-B (nsl) humidity probe 22-2-4
