FD720 Universal Moisture Balance

Description

The Advanced Professional Standard for Precision Moisture Analysis

The FD720 brings laboratory loss-on-drying — the primary gravimetric reference method that official methods and public regulations are built on — to the production QC bench, with the premium drying control and balance stability of higher-end analyzers. It suits chemicals, pharmaceuticals, foods, pulp and paper products, polymers, and most materials containing organic substances.

Solving Critical Laboratory Pain Points

• Eliminating heater maintenance: The mid-infrared quartz heating lamps average five to ten times the operating life of halogen or older infrared elements.  With a MTBF of roughly 20,000 to 30,000 hours of measured use, this feature lowers total cost of ownership by reducing element replacements.
• Guaranteed accuracy through long tests: Heat buildup causes scale drift on ordinary balances. Kett’s patented internal auto-taring system re-zeros the balance automatically throughout a run, keeping readings drift-free even on continuous tests of several hours. Because loss on drying is a primary gravimetric method, a result run to completion is definitive and traceable and not a value inferred from a correlation.
• Documentation built for GMP and GLP: Each result outputs over RS-232C as tab-delimited data straight into Microsoft Excel or a thermal printer.  There is no proprietary software required.  Password protection restricts settings changes, supporting the data-integrity and access-control practices these frameworks require.
• One instrument for varied samples: Six drying modes: automatic, timed, high-speed, low-speed, stepped, and predictive plus 120 g capacity and a 130 mm sample dish handle scorch-prone, bulky, or low-density materials that overflow the small pans on compact analyzers.

Built for Everyday QC

Operation is direct: set time and temperature, place the sample, close the lid, and press start. Ten stored measuring conditions recall the right profile for each material, and on-board memory holds 100 results. Every unit carries Kett’s One Year Total Care Warranty covering parts, labor, and specification compliance, with Maintenance Agreements available for calibration and ongoing support.

Drying samples that scorch before they read dry? The FD800 Dual Control Moisture Balance adds a non-contact sensor that reads sample-surface temperature directly, drying heat-sensitive materials quickly without burning them.

Don’t need 120 g capacity or six drying modes? The FD660 Compact Moisture Balance covers everyday loss-on-drying testing in a smaller, lower-cost package.
