Ellab TrackSense Pro Compact Wireless Temperature Validation System for Ultra-Low-Temperature Applications

Overview

The Ellab TrackSense Pro Compact is a purpose-engineered wireless temperature data logger designed specifically for ultra-low-temperature (ULT) validation and monitoring in regulated pharmaceutical, biologics, and cold-chain logistics environments. Operating on the principle of high-stability platinum resistance thermometry (Pt1000), the device delivers traceable, NIST-calibratable temperature measurements across an extended range from –90 °C to +140 °C—enabling rigorous thermal mapping of ULT freezers (–80 °C), cryogenic storage units, lyophilizers, autoclaves, and environmental chambers. Its compact form factor (Ø22 mm × 60 mm) allows unobtrusive placement within narrow vial racks, cryoboxes, or behind insulation layers without compromising thermal response time. Unlike generic loggers, the TrackSense Pro Compact is built as a GxP-compliant validation instrument—not merely a data collector—but a fully auditable component of a validated system architecture.

Key Features

• Integrated Pt1000 Class A RTD sensor with ≤ ±0.1 °C accuracy (at 0 °C) and ≤ ±0.15 °C uncertainty over –40 °C to +85 °C per ISO/IEC 17025-accredited calibration certificate
• Multi-parameter capability: Simultaneous temperature and optional absolute pressure measurement (0–110 kPa, ±0.5 kPa)
• Long-duration battery operation: Up to 30 days at 1-second logging intervals; configurable sampling rates from 0.1 Hz to 10 Hz
• Visual status indication via dual-color LED: Green (operational), Red (alarm or out-of-range), Flashing (startup or low-battery warning)
• Robust stainless-steel housing rated IP67 for resistance to condensation, cleaning agents, and mechanical shock
• Wireless synchronization and configuration via Ellab’s proprietary 2.4 GHz ISM-band protocol—no Bluetooth or Wi-Fi dependencies, ensuring electromagnetic compatibility in RF-sensitive cleanrooms

Sample Compatibility & Compliance

The TrackSense Pro Compact is validated for use in direct contact with pharmaceutical product containers, including cryovials, stainless-steel trays, and silicone-lined shelves. Its small footprint ensures minimal thermal mass interference during heat penetration studies and thermal distribution mapping. All devices ship with individual factory calibration certificates traceable to DKD/DAkkS-accredited laboratories. The system conforms to critical regulatory frameworks including FDA 21 CFR Part 11 (electronic records and signatures), EU GMP Annex 15 (Qualification and Validation), ISO 13485 (medical device quality management), and ASTM E2810 (standard practice for qualification of thermal processing equipment). Audit trails, user access controls, electronic signatures, and immutable data archiving are enforced through ValSuite® software—fully supporting GLP and GMP inspection readiness.

Software & Data Management

ValSuite® is the central validation data platform for Ellab’s entire ecosystem—including TrackSense Pro Compact, Frigo, and E-Val™ Pro wired systems. It supports concurrent acquisition from up to 160 wireless channels or 120 wired channels per workstation. The software provides real-time telemetry via the SKY cloud module (optional), enabling remote monitoring during sterilization cycles or freezer qualification without physical access. Reporting complies with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and generates automated IQ/OQ/PQ reports in PDF, CSV, and XML formats. ValSuite® integrates seamlessly with LIMS and MES platforms via OPC UA and RESTful APIs. Windows 10/11 native support, multi-language UI (EN, DE, FR, ES, CN, JP), and role-based permission management ensure operational continuity across global sites.

Applications

• Thermal mapping and qualification of ultra-low-temperature freezers (–80 °C) and liquid nitrogen storage dewars
• Validation of freeze-drying cycles—including shelf temperature uniformity, chamber pressure stability, and vial heat transfer profiles
• Autoclave and depyrogenation tunnel mapping per ISO 17665 and HTM 2030
• Cold chain monitoring during clinical trial material transport and warehouse ambient storage
• Environmental chamber qualification for stability testing (ICH Q1, Q5C)
• Temperature-pressure correlation studies in vacuum-assisted processes

FAQ

What is the recommended calibration interval for TrackSense Pro Compact loggers?

Ellab recommends annual recalibration against a certified reference standard in accordance with ISO/IEC 17025; however, frequency may be adjusted based on risk assessment, usage intensity, and internal SOPs.
Can the TrackSense Pro Compact operate inside a liquid nitrogen vapor phase?

Yes—the Frigo variant (–90 °C to +85 °C) is specifically engineered for prolonged exposure in LN₂ vapor-phase environments; the Compact variant (–90 °C to +140 °C) supports similar conditions but is optimized for higher-temperature applications requiring extended upper-range coverage.
Is ValSuite® compliant with FDA 21 CFR Part 11 for electronic signatures?

Yes—ValSuite® implements full Part 11 functionality: audit trail with immutable timestamps, electronic signature workflows with dual authentication, and secure user-role assignment with password complexity enforcement.
How is data integrity ensured during wireless transmission?

Each data packet includes CRC-16 checksums and sequence numbering; lost packets are automatically retransmitted upon handshake failure. All wireless communication is encrypted using AES-128 and operates on a dedicated frequency band to prevent interference.
Does the system support third-party sensor integration?

No—TrackSense Pro Compact uses only factory-integrated, calibrated Pt1000 sensors to maintain metrological traceability and eliminate field-sensor drift variables inherent in modular designs.
