Key Customer Challenges

“Can I trust my humidity measurement as a reference?”

MBW chilled mirror hygrometers directly determine dew or frost point and are used as transfer standards by national standards and accredited laboratories.

“How do I reduce humidity calibration uncertainty?”

Direct chilled mirror measurement, low drift, high repeatability and precise temperature measurement can reduce important contributors to measurement uncertainty.

“How do I validate the actual humidity inside my climatic chamber?”

The Model 473 places cable-mounted dew-point and temperature sensors directly in the test environment and is the MBW model Process Insights identifies as most commonly used for chamber applications.

“How do I measure dew point above ambient temperature?”

The Model 373 and 573 use temperature-controlled measuring heads and sample paths to enable high-dew-point measurement while helping prevent condensation before the sample reaches the mirror.

“What if I need measurements in the field?”

The Model 973 provides an integral measuring head in a portable platform for spot or continuous measurements.

ISO/IEC 17025 Humidity & Dew Point Calibration

Process Insights operates an ISO/IEC 17025-accredited humidity and temperature calibration laboratory accredited by DAkkS. Its calibration capabilities include dew point, frost point and relative humidity calibration, and Process Insights states that certificates are internationally recognized through the ILAC Mutual Recognition Arrangement.
