Overview

The document describes the specifications and operational guidelines for a Bench-Top Type Temperature Humidity Chamber, a device used for environmental testing by simulating various temperature and humidity conditions.

Specifications

• Temperature Range: Typically from -20°C to +150°C, allowing for a wide range of testing environments.
• Humidity Range: Usually from 20% to 98% relative humidity, enabling precise control of moisture conditions.
• Chamber Size: Compact bench-top design suitable for laboratory and production environments with limited space.
• Control System: Microprocessor-based controller with digital display for temperature and humidity settings and monitoring.
• Power Supply: Standard electrical requirements, often 220V or 110V depending on region.

Operational Procedures

• Pre-Operation Checks: Verify power supply, ensure chamber is clean and free of obstructions.
• Setting Parameters: Input desired temperature and humidity values via the control panel; allow stabilization time before testing.
• Sample Placement: Arrange test samples evenly inside the chamber to ensure uniform exposure.
• Monitoring: Continuously monitor parameters during testing to maintain conditions within specified tolerances.
• Post-Test Procedures: Gradually return chamber to ambient conditions before removing samples to avoid shock.

Standards and Compliance

The chamber complies with international environmental testing standards such as IEC, ASTM, and MIL-STD, ensuring reliability and repeatability of test results.

Recommendations and Best Practices

• Regular calibration of sensors to maintain accuracy.
• Routine maintenance including cleaning and inspection of seals and components.
• Avoid rapid changes in temperature or humidity to prevent damage to samples and equipment.
• Use of appropriate safety gear when handling extreme conditions.
