  • Features +


    High Temperature Testing:The heater of the Computrac® MAX® 5000XL can reach temperatures as high as 600ºC, giving it the ability to perform both loss on drying (LOD) and loss on ignition (LOI) testing and making it an ideal alternative to expensive, thermogravimetric analyzers.

    Rugged Construction: Equipped with a ruggedly designed metal casing and a high temperature heater, the MAX 5000XL is designed to provide lab quality data whether it is in the lab or on the production floor.

    Versatile: The MAX 5000XL is able to test material up to 100 times faster than standard reference methods and is ideal for everything from plastics and pharmaceuticals to foods, biomass materials and more.

    Flexible Ending Criteria: User adjustable ending criteria help to optimize test results and performance for your unique application or material.

    Real-Time Results:The MAX 5000XL 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.

    Multistage Testing: Several tests can be linked in order to form a single, multistage test that can change temperatures, ending criteria and times between each test segment. This allows the instrument to test for moisture, solids and ash content with a single sample.

    Self-Cleaning Oven: The oven of the MAX 5000XL features a self-cleaning cycle that simplifies routine maintenance. It runs for 45 minutes at 550ºC.

    Web Server: The optional web server allows users to monitor tests remotely and check in with operators. It also lets users download results and calibration reports, view the audit log and transfer programs between instruments.
