Features

• Improved repeatability and reliability by a new developed humidity sensor
• Measurement of relative humidity 0 to 100%RH by capacitance type humidity sensor
• Three types of wall-mounting type, separated type, heat-resistive separated type and insertion type (soft type and hard type) are prepared for various applications.
• Heat-resistive separated type can be used in the environment of -40 to 180°C
• Easy maintenance by complete interchangeable sensors
• DIN rail installation enabled (except insertion type)
• CE conformance
