Operations Manual

The Computrac® MAX® 5000XL moisture, solids, and ash analyzer can provide accurate readings from a single sample, offering many of the same features of thermogravimetric analyzers at a fraction of the cost. With a maximum temperature of 600°C and a maximum sample size of 100 grams, the MAX® 5000XL has the versatility for a wide range of material-testing tasks. 

  • Versatile: Get accurate readings for both ash and moisture content from a single sample.
  • Fast: Moisture and ash readings in half an hour or less.
  • Simple: One-button operation with no intermediate weighing or cooling steps required.
  • Durable: Made in the USA with an all-steel enclosure, the MAX 5000XL was designed for heavy-duty use.
  • Accurate: Correlates to popular methods, including ASTM D5630, ASTM D4574, ASTM E1534 and more.

Features and Benefits

  • 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, landing 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.
