The device supports up to 32 stored research methods and RS232 data output, providing lab managers with configurable tests and easy integration with printers or computers. Its aluminum enclosure and multi-story heating chamber contribute to safe, durable operation in busy plastics laboratories.
RUISHAN 50gx0.001g Moisture Analyzer
This RUISHAN model offers a compact 50 g capacity with 0.001 g weight readability and 0.01% readability. A 5-inch touch screen provides intuitive operation, coupled with three drying modes and two ending modes (automatic and timing) for flexible testing workflows. Like other RUISHAN units, it supports RS232 data transfer and CE/RoSH certifications. Its design focuses on straightforward operation without sacrificing measurement fidelity, making it suitable for plastics research and quality control environments where quick, accurate moisture readings are essential.
FLB FORELIBRA Moisture Analyzer
The FORELIBRA model provides a large 110 g sample capacity and a 0.01% readability with a 0.001 g resolution. Its multilingual 5-inch touch screen supports Spanish, English, German, and more, making it accessible for diverse lab teams. It features two test endings (automatic and timing) and adjustable drying speed (soft or fast), enabling precise control over moisture determination in plastics, powders, and related materials. The device includes 34 memory programs to minimize reconfiguration, and a heating temperature range from 40°C to 180°C for broad material compatibility. Certifications and robust build support daily laboratory use for plastics testing programs.
Buying Guide: Key Purchase Considerations For Plastic Moisture Analyzers
- Moisture Readability and Weight Readability: For plastics, a lower moisture readability (0.01%–0.1%) and fine weight readability (0.001–0.005 g) enable detection of tiny moisture variations that can affect processing and product quality.
- Drying Modes and End Modes: Look for at least three drying modes (standard, fast, soft) and multiple ending modes (automatic, manual, timing) to tailor tests to resin, masterbatch, or powder materials with varying moisture levels and textures.
- Capacity and Sample Type: Consider units with 50–110 g capacity for plastics pellets, powders, and masterbatches. Ensure the probe or chamber accommodates bulk materials and powders without excessive sample prep.
- Data Management and Output: RS232 or USB data output simplifies integration with printers and LIMS, while presets and memory programs speed routine testing and ensure consistency across batches.
- Calibration and Language Support: Models offering calibration assistance and multi-language menus help maintain measurement accuracy and support diverse lab teams.
- Durability and Certification: Aluminum enclosures, robust heating chambers, CE/RoHS certifications indicate suitability for professional lab use and long service life in manufacturing environments.
- Ease of Use and Maintenance: User-friendly touch screens, clear prompts, and accessible maintenance steps reduce operator error and downtime in high-volume settings.
- Application Versatility: If testing multiple plastic forms (resins, powders, fillers), prioritize meters with deep-penetration probes or adaptable accessories to ensure representative measurements.
