Model 2500 Benchtop/Mobile "Two-Pressure" Humidity Generator

Product catalog summary

Overview: The Model 2500 Benchtop/Mobile "Two-Pressure" Humidity Generator by Thunder Scientific Corporation is a self-contained system designed to produce atmospheres of known humidities using the NIST-proven "two-pressure" principle. It is suitable for instrument calibration, evaluation, verification, and environmental testing.

Features: The generator is automated, allowing for unattended operation. It includes a multifunction CPU for control and calculation, a bidirectional RS-232C interface for remote control, and a liquid crystal display for real-time system status. It offers a 0.5% RH uncertainty and is traceable to SI standards.

Principle of Operation: The system calculates relative humidity using pressure and temperature measurements. It does not rely on external devices for water vapor content measurement. The control system uses PID algorithms for temperature, pressure, and flow control, ensuring precision and stability.

Specifications: The Model 2500 operates at 100/120 V or 200/240 V, with an air compressor option. It supports a relative humidity range of 10 to 95% and a temperature range of 0 to 70°C (optional -10 to 70°C). The chamber pressure is ambient, with a gas flow rate range of 5 to 20 L/min.

Applications: The generator is suitable for testing humidity sensors, hygrothermographs, chilled mirror hygrometers, and various materials. It can evaluate humidity calibration accuracy, operational checks, and environmental testing for products sensitive to humidity.

Physical Dimensions: The generator's dimensions vary based on the model and configuration, with detailed measurements provided in tables for standard and cart-mounted setups.

Additional Information: The system includes features like computerized internal transducer calibration, low noise air compressor, and HumiCalc® software with uncertainty analysis. Custom options for access ports are available.
