Calibration enabled Hygrometer with changeable probe for all operational areas
The relative air humidity plays a decisive role in many industrial applications and quality assurance activities. In industrial applications, the requirements for a hygrometer are quite stringent in terms of measuring accuracy, long term stability and features. Often special probes are required suiting to the application.
The portable instruments of series HM 309 have been developed based on these criteria: These high quality and robust instruments are fitted with capacitive humidity sensors and offer an outstanding measuring accuracy of up to 1 % rH.
The external probe is plug-in type and is changeable. Besides the standard probes with 2 % measuring accuracy, special probes are also available for the instrument for various types of special applications, for example, pressure resistant dew point probe for pneumatics, different type of bulk goods probe or stationery mounted probes. Customised special probes are also available for special applications, with which practically almost all application areas get well covered.
