TESTED ARIZONA CT-3100-L Computrac Vapor Pro VP Series Moisture Analyzer
Used. Has a scratch on the top plastic that did not damage or alter any component functions. Power Cable, nitrogen generation (sheath gas) supply, and compressed gas tube are NOT included, only used for testing. See attached photos.
A demonstration video is uploaded to Youtube to see some of the CT-3100-L's functions. The graphs describe the rate of moisture loss and the total moisture curve of the material that is heated.

About this system, "The Arizona Instrument / AZI Computrac Vapor Pro CT-3100-L is a moisture-specific laboratory and production-floor moisture analyzer designed as a chemical-free alternative to Karl Fischer coulometric titration. The system heats a sample in a sealed septum vial while dry air or dry nitrogen carrier gas sweeps evolved moisture through the internal sensor block; the instrument uses a polymer-capacitor relative humidity sensor, sensor-block temperature, and carrier-gas flow data to calculate moisture content as ppm H₂O, % moisture, or total micrograms of water. The CT-3100-L Vapor Pro is designed for low-level water/moisture analysis with a stated lower detection limit of 10 µg / 10 ppm / 0.0010%, 25°C to 275°C electronically controlled heating, RS-232 output, printer/balance connections, and reagent-free operation for QA/QC, plastics, polymers, resins, powders, chemicals, pharmaceuticals, petroleum products, food ingredients, raw materials, hygroscopic samples, production testing, incoming inspection, process control, and general laboratory moisture determination. The manual describes the Vapor Pro as storing programs for up to 102 materials and retaining recent sample results, with user-adjustable temperature, purge, and ending criteria for optimizing speed and accuracy."
