MADGETECH TransiTempII Temperature Data Logger

Overview

The MADGETECH TransiTempII is a compact, self-contained, battery-powered temperature data logger engineered for long-term, unattended environmental monitoring in industrial, pharmaceutical, logistics, and laboratory settings. It operates on the principle of high-stability thermistor-based temperature sensing, calibrated traceably to NIST standards, and records time-stamped measurements at user-defined intervals without requiring external power or host connectivity during deployment. Designed for robustness in dynamic thermal environments—from cold-chain transit to HVAC validation—the device features an IP67-rated polycarbonate enclosure that resists dust ingress, moisture immersion up to 1 m for 30 minutes, and mechanical shock per MIL-STD-810G. Its internal memory stores up to 32,767 timestamped readings, enabling continuous monitoring over extended durations (e.g., 12 months at 30-minute intervals), with data retrieval via plug-and-play USB-A interface and MADGETECH’s free, validated software suite.

Key Features

• High-accuracy thermistor sensor with ±0.5 °C total system accuracy across –40 °C to +80 °C operating range, verified at multiple points during factory calibration.
• Configurable logging interval from 1 second to 18 hours—supporting both rapid transient capture and multi-month trend analysis.
• Three start modes: immediate initiation, programmable delayed start (up to 100 days), or event-triggered logging (temperature threshold crossing or external contact closure).
• Non-volatile flash memory retains data even during battery replacement; no data loss under power interruption.
• USB-A direct-connect interface eliminates need for proprietary cables or drivers—fully compatible with Windows 10/11, macOS 12+, and modern Linux distributions.
• Battery life rated up to 1 year under typical conditions (25 °C ambient, 1-minute logging interval); low-battery indicator alerts prior to end-of-life.
• Compact form factor (63.5 × 31.8 × 25.4 mm) and lightweight design (34 g) enable mounting in confined spaces, inside insulated containers, or attached to packaging via adhesive pad or mounting clip.

Sample Compatibility & Compliance

The TransiTempII is designed for non-invasive, ambient air or surface temperature monitoring—not for immersion in liquids or direct contact with corrosive agents. It complies with international regulatory and quality frameworks relevant to data integrity in regulated industries: RoHS Directive 2011/65/EU, CE marking per EMC Directive 2014/30/EU and RED Directive 2014/53/EU, and FCC Part 15 Subpart B Class B emissions requirements. While not intrinsically safe, its low-power architecture and sealed housing make it suitable for use in non-hazardous locations per IEC 60079-0. For GxP applications—including GDP (Good Distribution Practice) and GLP (Good Laboratory Practice)—the device supports audit-ready data export (CSV, PDF, XML) with embedded metadata (serial number, firmware version, calibration date, user-defined ID). Optional IQ/OQ documentation packages are available to support validation per FDA 21 CFR Part 11 and ISO 17025 requirements.

Software & Data Management

MADGETECH’s free Logger Software (v5.x, Windows/macOS) provides full configuration, real-time graphing, statistical analysis (min/max/mean/std dev), alarm threshold setup, and report generation. All data files include cryptographic checksums to ensure integrity, and the software maintains immutable audit trails of all configuration changes and data exports. Export formats comply with common LIMS and ELN integration requirements: timestamped CSV with ISO 8601 formatting, PDF reports with digital signature fields, and XML schemas aligned with ASTM E2047–22 (Standard Guide for Data Exchange in Environmental Monitoring). No cloud dependency—data remains fully under user control on local systems. Firmware updates are delivered via signed binary packages with SHA-256 verification.

Applications

• Cold chain validation and monitoring for pharmaceutical shipments (per WHO TRS 961 Annex 9 and EU GDP guidelines).
• Warehouse and storage facility temperature mapping per ISO 14644-3 and USP .
• Stability chamber qualification and routine performance verification.
• Transportation validation for clinical trial sample logistics (ICH-GCP compliant data retention).
• Process equipment thermal soak studies and autoclave cycle verification support.
• Environmental monitoring in cleanrooms, museums, and archival repositories where passive, low-maintenance logging is critical.

FAQ

Is the TransiTempII calibrated, and is calibration traceable to NIST?
Yes—each unit ships with a Certificate of Calibration documenting multi-point verification against NIST-traceable standards. Optional annual recalibration services are available through MADGETECH-accredited labs.
Can the device be used in refrigerated trucks or ultra-low temperature freezers?
The standard TransiTempII model is rated for –40 °C to +80 °C. For sustained operation below –40 °C, the Cryo-Temp variant (–86 °C to +35 °C) is recommended.
Does the logger meet FDA 21 CFR Part 11 requirements for electronic records?
While the hardware itself does not enforce Part 11 controls, the Logger Software supports electronic signatures, audit trails, and secure data export—enabling compliance when deployed within a validated organizational IT infrastructure.
How is data security handled during USB transfer?
No authentication or encryption is applied during USB readout; physical access control is the primary security measure. Users deploying in sensitive environments should implement endpoint security policies consistent with ISO/IEC 27001.
What is the warranty and repair policy?
MADGETECH provides a 2-year limited warranty covering defects in materials and workmanship. Repair turnaround is typically 5–7 business days upon receipt at authorized service centers.
