The PMB Moisture Analyzer is a laboratory instrument designed for the determination of moisture content in various materials. It offers a range of features and specifications that make it suitable for diverse applications.
Function Description:
The PMB Moisture Analyzer operates by heating a sample to dry it, and then measuring the mass loss to determine the moisture content. It supports various drying methods, including single temperature, ramp to temperature, and step temperature, allowing for flexibility in testing different sample types. The analyzer can store up to 99 test results and settings, which can be recalled for repeated tests or analysis. It also features a USB host connection for memory devices, enabling the storage and transfer of test data. The device can be connected to a PC via RS-232 or USB for data collection and control using AdamDU Data Collection software.

Maintenance Features:
- Cleaning: The analyzers should be cleaned regularly, and spills in the weighing chamber should be cleaned up before they become baked on.
- Protection: Avoid extreme temperatures, direct sunlight, or near air conditioning vents. Ensure the analyzer is on a strong, stable, and vibration-free table. Avoid unstable power sources and large users of electricity. Keep the analyzer free from vibration. Avoid high humidity and direct contact with water. Do not spray or immerse the analyzer in water.
- Safety: The PMB Moisture Analyzer complies with European Council Directives and international standards for electromagnetic compatibility and safety requirements. Users are advised to read operating instructions thoroughly. Improper use or handling can result in damage or injury. The moisture analyzer must be operated by trained personnel.
- Hot Surfaces: The heating chamber can become very hot. Keep all material away from the vent area. Do not touch hot surfaces. Leave 20 cm (about 8 inches) around the moisture analyzer and 1 m (3 ft.) above. Samples will be hot after a test. Do not use bare fingers to pick up any samples pans or touch the materials.
- Materials: The PMB Moisture Analyzer is not suitable for all materials. Drying process samples will be heated to high temperatures. Materials that are flammable or explosive should not be tested. Materials that emit toxic, caustic, or noxious fumes should only be tested in suitable fume hoods or with other ventilation. Materials that will have a film on the surface during drying may cause high internal pressures to be present. These materials should not be tested using this method. Materials that emit aggressive or corrosive fumes (such as acids) should be tested using small quantities of material in an area with good ventilation.
- Troubleshooting: The manual provides guidance on troubleshooting common issues, such as error messages during calibration or loading configuration files.
