Humidity verification for environmental chambers
The Optidew cooled mirror dewpoint hygrometer is stable, fast responding and accurate over the whole operating range of an environmental chamber, from the driest conditions to saturation.
Dewpoint meter is precise about humidity
Optidew Vision is a precision dewpoint meter with an LCD panel.
Offering unrivalled flexibility, Optidew features a wide dynamic measurement range from -50 to +90C dew point over a temperature range of -40 to +90C, equivalent to a humidity range of 2 to 95% RH at temperatures up to 90C.
By measuring the dew point temperature directly, using a high-quality platinum resistance thermometer, Optidew offers absolute precision with drift-free, long-term performance.
Optidew also offers far better accuracy and stability than traditional polymer RH probes, particularly at low relative humidities.
Built to last, Optidew features a rugged, IP65 housing capable of withstanding the most demanding industrial conditions, while retaining the performance and sensitivity of a high-level laboratory reference hygrometer.
Optidew provides two 4-20mA output signals, configurable through the instrument's interfacing software to dew point and temperature or relative humidity and temperature.
The RS232 interface allows connection to custom data logging and configuration software, operating under a Windows environment.
Optidew's design also takes into account contamination, which can compromise the accuracy of many cooled mirror dew-point meters, and as such features Michell Instruments' new dynamic contamination correction (DCC) system.
The DCC system automatically eliminates any error that may be caused by mirror particle contamination, and intelligently adapts itself to accommodate particular applications from the dirtiest of processes to the cleanest semiconductor applications.
Optidew can be mounted in a variety of ways such as directly into the process, flange mounted, tee mounted or via an external sample line, and is available with a range of options including up to 250 metres of cable for the remote sensor, probe sensor mounting arrangement, special measurement ranges and sintered stainless steel sensor guard.
