Intuitive user interface

Equipped with a 7-inch color LCD touch screen, the operation interface is simple and intuitive, bringing users a convenient interactive experience.

Real-time curve display

It has powerful data visualization capabilities and supports real-time display of temperature, humidity, and pressure curves, allowing users to intuitively grasp data change trends.

Accurate calibration function

Supports multi-point correction of temperature, humidity and pressure to ensure the reliability of measurement data.

Intelligent conversion software

Integrated with professional humidity conversion software to allow fast calculation of relative humidity, temperature, and dew point temperature.

Communication interfaces

Supports RS232 or RS485 communication for easy data exchange and system integration with external equipments.

Modular power and communication

Provides separate power and communication modules for sensors under calibration, enhancing flexibility and adaptability to diverse application scenarios.

Efficient structural design

The measuring chamber features a transparent window and internal lighting for easy reading of small temperature and humidity instruments. An external drying cylinder design allows desiccant replacement during operation. Dual-zone drying cylinders support both molecular sieves and silica gel desiccants. Visual display of liquid level and desiccant status enables real-time monitoring.

Flexible calibration point configuration

Temperature calibration includes multiple points: -10 °C, 0 °C, 20 °C, 30 °C, and 40 °C, with a scientifically sequenced calibration process starting from sub-zero and gradually increasing to prevent frosting. Relative humidity calibration covers 30%, 50%, and 80% RH, precisely targeting common calibration ranges. Atmospheric pressure calibration points can be flexibly set according to local standard, upper, and lower atmospheric pressure values, ensuring accurate and practical calibration results across regions.

Standardized, efficient calibration workflow

The preparation before calibration is simple. After preheating, place the sensor from the weather unit under test in the center of the calibration chamber and close the lid to begin. During calibration, once each setpoint stabilizes, data is recorded at one-minute intervals to ensure efficient and orderly execution, delivering reliable calibration results to the user.
