Duling C1-C0P-10 Multi-Channel Wireless Temperature Data Logger

Overview

The Duling C1-C0P-10 is a compact, battery-powered wireless temperature data logger engineered for continuous, unattended monitoring in cold chain logistics, pharmaceutical storage, cryogenic sample repositories, and laboratory environmental validation. It operates on the principle of precision thermistor-based temperature sensing, with analog-to-digital conversion performed locally at the sensor node. The device digitizes temperature readings, applies factory-calibrated compensation algorithms, and transmits time-stamped data via a proprietary 433 MHz or 868 MHz ISM-band RF protocol—optimized for low-power, long-range, and wall-penetration robustness. Unlike Bluetooth or Wi-Fi loggers, the C1-C0P-10 eliminates dependency on local network infrastructure, making it suitable for remote freezers, transport containers, and off-grid warehouse zones where IT connectivity is unreliable or prohibited. Its operational envelope spans from liquid nitrogen immersion (−196 °C) to high-temperature incubation environments (+100 °C), with certified accuracy of ±0.1 °C across the clinically critical −50 °C to +50 °C range—meeting foundational requirements for ISO 13485-aligned medical device storage and USP cold chain verification.

Key Features

• High-fidelity thermistor sensing with NIST-traceable calibration certificate option
• Configurable sampling interval (1–10 minutes) supporting both event-driven and periodic logging modes
• Integrated OLED display showing real-time temperature, user-defined upper/lower alarm thresholds, and battery status
• Low-power RF transmission architecture enabling >12 months of operation on standard CR123A batteries (typical usage)
• Robust mechanical housing rated IP65 for resistance to condensation, dust ingress, and mechanical shock during transit
• On-device LED alarm indicators synchronized with audible alerts (optional firmware-enabled)
• Modular design supporting field-replaceable sensor cables and hot-swappable battery compartments

Sample Compatibility & Compliance

The C1-C0P-10 is compatible with industry-standard PT100, PT1000, and NTC 10kΩ thermistors (via optional adapter modules), enabling adaptation to diverse sample contact geometries—including vial probes, surface-mount sensors, and immersion sleeves. It complies with CE RED Directive 2014/53/EU for radio equipment and meets RoHS 2011/65/EU substance restrictions. While not intrinsically safe-certified, its low-voltage DC operation (<3.6 V) and absence of spark-prone components permit deployment in non-hazardous classified areas per IEC 60079-0. For regulated environments, the device supports audit-ready data export in CSV and PDF formats, including embedded timestamps, sensor ID, and calibration metadata—facilitating alignment with FDA 21 CFR Part 11 (when paired with validated host software), EU Annex 11, and WHO Technical Report Series No. 961 cold chain guidelines.

Software & Data Management

Data retrieval is performed via a dedicated USB-connected base station (C1-GW-01, sold separately) that aggregates transmissions from up to 256 distributed C1-C0P-10 nodes within its coverage radius. Host software—Duling TempLog Suite v3.2—provides GxP-compliant features including role-based user access control, electronic signature workflows, automatic report generation (per ISO/IEC 17025 clause 7.8.2), and configurable alarm escalation (email/SMS via SMTP/GSM gateway). All logged datasets retain immutable audit trails recording parameter changes, manual overrides, and firmware updates—enabling full traceability required under GLP and GDP frameworks. Raw binary logs are encrypted using AES-128 prior to storage; decrypted exports retain native timestamp resolution of 1 second.

Applications

• Real-time monitoring of ultra-low temperature (ULT) freezers storing mRNA vaccines and biobanked cell lines
• Temperature mapping studies for walk-in cold rooms and refrigerated trucks (ICH Q5C, WHO TRS 961)
• Validation of lyophilization cycle chamber uniformity and shelf temperature stability
• Long-term stability testing chambers per ICH Q1A(R2) and USP
• Environmental surveillance in cleanrooms (ISO 14644-3) and sterile manufacturing suites
• Post-distribution temperature integrity verification for clinical trial supply chains

FAQ

Is the C1-C0P-10 suitable for use inside liquid nitrogen dewars?

Yes—the sensor input and enclosure are rated for continuous operation at −196 °C when paired with a cryo-optimized probe (e.g., silicon diode or carbon-glass composite sensor); standard NTC probes require derating below −80 °C.
Can multiple C1-C0P-10 units be deployed in the same facility without interference?

Yes—each unit is assigned a unique 32-bit node ID during commissioning; the base station performs frequency-hopping spread spectrum (FHSS) demodulation to isolate concurrent transmissions.
Does the device support external power or only battery operation?

Battery-only operation is standard; however, a 5 V DC auxiliary power input option (C1-EXT-POE kit) is available for fixed-installation deployments requiring continuous uptime.
How is calibration traceability documented?

Each unit ships with a factory calibration report referencing NIST SRM 1750 (certified reference thermometer); accredited third-party recalibration services are available through Duling’s ISO/IEC 17025-certified metrology lab.
Is firmware update capability supported over-the-air?

No—firmware updates require physical USB connection to the base station and must be performed using signed binaries issued by Duling’s authorized support portal.
