Traceable 56000-16 Four-Channel Programmable Timer with NIST-Traceable Calibration

Overview

The Traceable® 56000-16 Four-Channel Programmable Timer is an engineered precision timing instrument designed for regulated laboratory, clinical, and industrial environments where traceable time measurement is essential. Operating on the fundamental principle of quartz crystal oscillation with temperature-compensated circuitry, it delivers stable, repeatable timekeeping across all four independent channels. Unlike generic consumer timers, this device is purpose-built for compliance-critical workflows—such as sample incubation, reagent reaction monitoring, sterilization cycle verification, and QC test duration control—where documented metrological traceability to the International System of Units (SI) via the National Institute of Standards and Technology (NIST) is required. Its design adheres to foundational metrological principles outlined in ISO/IEC 17025:2017, ensuring that each unit ships with a unique, laboratory-issued Traceable Certificate confirming calibration against primary time standards.

Key Features

• Four fully independent timing channels—each configurable for countdown, count-up, or digital clock mode—with simultaneous operation and channel-specific alarm activation.
• Ergonomic, low-profile chassis with integrated clip, magnetic backing, and non-slip rubber feet for flexible mounting on fume hoods, biosafety cabinets, centrifuge lids, or benchtops without compromising stability.
• High-contrast, triple-line LCD display with 0.75-inch digits; supports both 12-hour and 24-hour time formats and retains visibility under gloved-hand operation and ambient lab lighting conditions.
• Tactile, oversized push-button interface with antimicrobial coating compliant with ISO 22196:2011, minimizing bioburden accumulation in high-touch clinical and diagnostic settings.
• Onboard memory retains the last programmed countdown value per channel, enabling rapid re-execution of standardized protocols without manual re-entry.
• Programmable audible alarm per channel—distinctive tone, adjustable volume, and 60-second sustained output—with visual alert indication via LCD flashing; silenced instantly via any button press.
• Factory-calibrated with documented uncertainty budget; supplied with individual Traceable Certificate (A2LA Accreditation No. 1750.01), satisfying audit requirements for GLP, CLIA, CAP, and ISO 15189-compliant laboratories.

Sample Compatibility & Compliance

The 56000-16 imposes no sample interaction—it is a passive timing reference instrument—and therefore exhibits universal compatibility across biological, chemical, pharmaceutical, and materials testing applications. Its metrological validity is maintained under standard ambient laboratory conditions (15–30 °C, ≤80% RH, non-condensing). The device meets the technical and documentation requirements for time-critical procedures referenced in USP , ASTM E2500-13 (Section 7.2.3), and FDA 21 CFR Part 11 when used in conjunction with validated electronic record systems. The included NIST-traceable certificate satisfies ISO/IEC 17025 clause 6.4.10 (traceability of measurements) and supports internal audit trails for time-stamped process validation events.

Software & Data Management

This timer operates as a standalone hardware device with no embedded firmware update capability or software dependency. All configuration and operation are performed directly via front-panel controls. Time logs, alarm triggers, or channel states are not stored electronically beyond volatile memory retention (i.e., last set value per channel). For laboratories requiring electronic data capture, integration is achieved through external documentation practices: users manually record channel start/stop times, alarm occurrences, and elapsed durations into LIMS, ELN, or paper-based batch records—consistent with ALCOA+ data integrity principles. The Traceable Certificate provides the necessary metrological foundation for such manual entries to be considered reliable and auditable.

Applications

• Monitoring enzymatic reaction kinetics in clinical chemistry analyzers.
• Validating hold times during sterile filtration and aseptic processing.
• Tracking incubation periods for microbiological culture media (e.g., ISO 4833-1:2013, AOAC 977.27).
• Enforcing exposure durations in UV disinfection validation studies.
• Controlling dwell times in automated immunoassay wash cycles.
• Supporting timed interventions in animal research protocols governed by IACUC guidelines.
• Verifying thermal equilibration intervals prior to DSC or TGA sample loading.

FAQ

Is the Traceable 56000-16 suitable for use in FDA-regulated GMP environments?
Yes—its NIST-traceable calibration certificate, issued by an A2LA-accredited laboratory operating under ISO/IEC 17025:2017, fulfills the metrological assurance requirements for time-critical steps in GMP manufacturing and quality control.
Does the timer require periodic recalibration?
No. The device is supplied with a one-time, factory-applied calibration valid for its intended service life under normal use conditions. Recalibration is not mandated unless physical damage, exposure to extreme environmental stress, or audit findings indicate performance deviation.
Can the alarm sound be disabled entirely?
No—the alarm function is integral to the timer’s design and cannot be permanently disabled; however, volume is adjustable, and alarms silence immediately upon button press.
What is the expected battery life under typical lab usage?
With continuous display and infrequent alarm activation, a single AAA battery typically lasts 12–18 months; low-battery indicator appears as dimmed LCD segments.
Is the device compatible with glovebox or cleanroom use?
Yes—the sealed housing, antimicrobial surface treatment, and absence of ventilation grilles meet ISO 14644-1 Class 5 particulate requirements when handled using appropriate cleanroom protocols.
