Linear Drying Time Recorder LLDT-A11

Labtron’s LLDT A11 uses a stepper motor drive with closed-loop control and photoelectric sensors to ensure needle movement remains accurate throughout long runs—even up to 60–200 hours. This system continuously monitors needle position and corrects any missed steps, keeping precision within <1% error as required by ASTM D5895 and ISO 9117 4 standards. The motorized travel also features an auto-stop at the end of each preset cycle, eliminating over run risks. Combined with calibrated 2?mm hemispherical needles and stainless weights, the setup delivers consistent, repeatable results for all stages of drying—evaporation, sol-gel, surface dry, and through-dry.

Yes, the LLDT A11 supports both preset cycles (6, 12, 24, 48?h) and fully programmable time ranges from as short as 1 minute up to 60 or even 200 hours, selectable via a touchscreen or buttons. Although all six tracks run simultaneously, each can be assigned individual time settings, allowing you to conduct comparative experiments—such as testing rapid versus slow curing coatings—in one session. Saved profiles simplify repeat testing, while the flexible timing elevates experimental versatility for R&D work alongside routine QC tasks.

Labtron supplies premium linear drying time recorder LLDT-A11.The instrument features a backlit touchscreen/LCD display and LED channel indicators, which show elapsed time, active tracks, and time remaining for each sample. A graduated scale ruler alongside the needle carriage maps needle position to critical drying stages-such as continuous tracks (gelation), intermittent tracks (surface dry), and cessation (through-dry). Together, these visual aids let users observe drying behavior live, pinpointing drying endpoints without manual data extraction.

Labtron’s linear drying time recorder LLDT A11 sports a lubricant-free drive train and sealed chassis, enabling operation in environments from –20?°C to +70?°C, including climate chambers, without lubricant freezing or motor binding. The heated display remains visible under low temperatures, and robust build materials withstand humidity and solvent exposure. These features allow direct testing of coatings under realistic environmental conditions—without moving samples, preserving test fidelity.

Labtron supplies premium linear drying time recorder LLDT-A11.It is shipped with stainless steel needle weights and a traceable calibration certificate, ensuring compliance with international standards. Annual UKAS/ISO 17025 calibration is recommended to verify motor timing accuracy and sensor function. For daily validation, use reference coatings and inspect needle impressions against known drying markers. Clean glass strips and photo-sensors regularly with isopropanol to avoid residue buildup. These routines keep measurement integrity intact and support regulatory traceability in QC and R&D workflows.

Labtron supplies advanced linear drying time recorder. The instrument supports concurrent testing of multiple coating samples—typically six—on separate parallel tracks, enabling direct comparison under identical conditions. This parallel setup drastically improves lab throughput compared to sequential testing, reducing testing time and increasing efficiency. Results can be reviewed side by side, simplifying differentiation between formulations or environmental responses. This simultaneous functionality is ideal for R&D screening, batch QA, and field checks. Consistent environmental exposure ensures that differences arise from sample properties—not testing variance. This capability streamlines workflows and supports fast decision-making in production or formulation teams.

Labtron linear drying time recorder offers flexible timing control, with both preset cycles and fully customizable durations to suit a wide range of formulations. Presets typically include standard timelines, while custom options allow adaptation for rapid-drying or slow-curing materials. Timing can be adjusted from just minutes to multiple days, covering everything from quick primers to heavy adhesives. Users set and monitor intervals through a clear digital interface with real-time time tracking. This flexibility ensures tests align precisely with each product’s behavior. It enhances both process accuracy and adaptability across multiple industries. The broad timing range also supports regulatory compliance and detailed study.

Labtron’s modern units feature intuitive, backlit LCD or touchscreen displays with easy-to-use menus and soft-touch buttons. Displays provide real-time tracking of elapsed time, active tracks, and drying stage indicators. Glass front panels allow easy cleaning and protect internal components, even in harsh lab environments. Heated screens and illuminated buttons support operation in varying ambient conditions. Visual cues guide users through test setups and clearly show test status. These ergonomic design elements minimize operator error and training time. They also ensure precise, user-friendly performance in both lab and field applications.

Labtron linear drying time recorder uses motor-driven or microchip-controlled mechanisms that deliver consistent, precise needle movement across all tracks Stepper or constant-speed motors maintain uniform travel and contact pressure, while lubricant-free drives prevent contamination. Rigid frames resist vibration, preserving track accuracy. The needle assembly includes calibrated weights for reproducible pressure. Needle holders and glass beds are reusable and easy to maintain, safeguarding instrument longevity This mechanical stability and precision foster reliable, repeatable test results essential for QA/QC and research protocols.

Labtron linear drying time recorder is designed for use across a wide temperature and humidity range thanks to heated displays, cleanable surfaces, and lubricant-free drives. It can operate in climate-controlled chambers or extreme environments between sub-zero and high-heat conditions. Glass beds tolerate solvent exposure and are easy to clean post-test. Users can log environmental conditions alongside drying data for audit purposes. This ensures comparability in inter-lab or batch validation studies. High environmental resilience makes the instrument suitable for R&D, QC labs, or field work-supporting consistent performance under diverse conditions.
