Optica Chilled Mirror Dew Point Meter

# Product Introduction
The chilled mirror dew point hygrometer can serve as a transfer standard for calibrating other humidity measuring instruments and sensors. It is the primary choice for process and laboratory applications requiring high-precision and drift-free measurements. The Optica can be equipped with 5 interchangeable chilled mirror sensors, covering a dew point measurement range from -80°C to 85°C (-112°F to 185°F) with an accuracy of 0.2°C (0.36°F) or better.
