The Optica series chilled mirror hygrometers offer NIST traceable humidity, temperature and pressure measurements for the connected generation. Now humididity reference data is acessible from anywhere, anytime from within a browser over the internet or your intranet.
The Optica measures dew point temperature by regulating the temperature of a polished metal mirror by the use of optical feedback such that a constant mass of dew or frost is maintained. The temperature of the mirror is measured with a precise PRTD and is by definition equal to the dew or frost point.
This Primary Standard has the following Features and Benefits
-
Simultaneously measure and display dew point, temperature, and pressure
-
Display any humidity parameter
-
Ethernet ready, so you can access GE Optica hygrometers via the Internet for remote monitoring applications
-
Data logger function lets you record & upload weeks of data
-
Primary NIST Traceable Humidity Transfer Standard
-
Accuracy to +/- 0.15°C
Dew-10 Series
Transmitters Dew-10 Series - GE General Eastern Description The Dew-10 Series is a family of low cost, high performance chilled mirror dew point transmitters comprising pipe, duct, and wall mount models. All models provide accurate and reliable dew point measurements over a wide range for energy management and process applications. Accuracy for the series is +/- 0.5ºC (+/- 1ºF). Dew point may be measured over a range of -40º to +58ºC (-40º to +136ºF). The wall mount version is also available with an optional air temperature measurement capability over the same range.
