Computrac® MAX® 4000XL
Moisture/Solids Analyzer

The Computrac® MAX® 4000XL provides the same reliability and ruggedness as the MAX® 2000XL, but with 25% faster throughput!

Significant performance enhancements including uniform heating and a lid fan that rapidly cools the heat chamber to reduce time between tests allow for greater ease of use and accuracy. A color LCD comes standard on this instrument to make it more user friendly.

The Parameter Expert feature available assists a user with the development of a test that will produce results that match a specified reference method. An optional web server allows a user with Internet Explorer to download a complete calibration report, view the LCD screen, download and upload test programs, download test results and test graph data, and download an audit log. The audit log tracks test program changes, calibrations, test result deletions, system errors and power on events.
