World-class support: Should you encounter a challenging application, our team of moisture analysis experts is here to help, free of charge.
Features and Benefits
- Rugged Construction: Equipped with an all-steel enclosure and a durable nickel chromium heating element, the Computrac® MAX® 4000XL is designed to provide lab-quality data whether it is in the lab or on the production floor.
- Rapid Cooling System: The built-in lid fan quickly cools the heating chamber to reduce the time between tests and increase overall throughput by 25%.
- Versatile: The MAX 4000XL is able to test material up to 100 times faster than standard oven reference methods and is ideal for everything from plastics and pharmaceuticals to foods, chemicals, and more.
- Flexible Ending Criteria: User-adjustable ending criteria help to optimize test results and performance for your unique application or material.
- Multistage Testing: Several tests can be linked in order to form a single, multistage test that can change temperatures, landing criteria, and times between each test segment. This is especially useful for method development and for measuring both free and bound moisture in products that contain waters of hydration.
- Real-Time Results: The MAX 4000XL offers simple, menu-driven operation and a user-programmable interface with a keypad and large color display that allows users to view real-time moisture curve and rate of moisture loss graphs during testing.
- Web Server: An optional web server allows users to download calibration reports, view the LCD screen, download the audit log, and upload and download test programs, results, and graphs.
- Data Storage: The MAX 4000XL stores up to 250 test programs and retains the last 1000 test results and the last 100 test graphs.
