Duling C1-AGP-10 Multi-Channel Wireless Temperature & Humidity Data Logger

Overview

The Duling C1-AGP-10 is a compact, battery-powered wireless temperature and humidity data logger engineered for continuous, unattended monitoring in cold chain logistics, pharmaceutical storage, biorepository environments, and laboratory-grade sample transport. It operates on the principle of high-stability thermistor-based sensing combined with digital signal conditioning and low-power wide-area network (LPWAN) telemetry. Designed for compliance-critical applications, the device captures environmental parameters at user-defined intervals and transmits encrypted time-stamped data to a secure cloud platform via embedded LTE-M, NB-IoT, or configurable Wi-Fi modules. Its extended low-temperature capability (down to −196 °C) enables validated use in liquid nitrogen cryogenic workflows—such as cell banking, mRNA vaccine transport, and ultra-low temperature freezer validation—where conventional loggers fail. The integrated OLED display provides immediate local verification of current readings without requiring external hardware, supporting rapid visual audits during loading, transfer, or receipt.

Key Features

• Ultra-wide temperature measurement range: −196 °C to +100 °C, certified for cryogenic and ambient applications
• High-fidelity thermistor sensor with ±0.5 °C accuracy across the full operating range (calibration traceable to NIST-traceable standards)
• Configurable sampling interval from 1 minute to 10 minutes, supporting both high-resolution event capture and extended battery life
• Onboard OLED display for real-time local readout of temperature, humidity (if equipped), timestamp, and signal status
• Embedded dual-mode wireless communication: factory-configurable LTE-M/NB-IoT for cellular coverage or Wi-Fi for facility-local deployment
• IP65-rated enclosure with reinforced polycarbonate housing for resistance to condensation, mechanical shock, and thermal cycling
• Internal rechargeable lithium-thionyl chloride (LiSOCl₂) battery rated for ≥12 months of operation at 10-minute intervals (typical usage)

Sample Compatibility & Compliance

The C1-AGP-10 supports direct connection to industry-standard external probes—including Class A Pt100 RTDs and calibrated capacitive humidity sensors—via its isolated analog or Modbus RTU (RS485) interface. It is suitable for monitoring temperature-sensitive payloads including vials, syringes, cryoboxes, insulated shippers, and walk-in cold rooms. From a regulatory standpoint, the device meets functional requirements for data integrity under EU Annex 11, FDA 21 CFR Part 11 (when deployed with audit-trail-enabled cloud software), and WHO Technical Report Series No. 961 (TRS 961) for cold chain validation. Raw data export is supported in CSV and PDF formats with embedded digital signatures; all transmissions comply with TLS 1.2+ encryption and support certificate-based mutual authentication.

Software & Data Management

Data from the C1-AGP-10 is ingested into Duling’s cloud-based ColdChainIQ platform, which provides role-based access control, automated alarm escalation (SMS/email/push), configurable threshold alerts, and electronic batch records. The platform generates GxP-compliant reports—including calibration history, deviation logs, and trend analysis—with full audit trail functionality (user actions, configuration changes, data edits). All stored data is retained for ≥36 months and may be exported in ISO/IEC 17025-aligned formats for internal QA review or regulatory submission. Integration with enterprise systems (e.g., SAP EHS, TrackWise, Veeva Vault) is supported via RESTful API and HL7/FHIR adapters.

Applications

• Real-time monitoring of mRNA, viral vector, and monoclonal antibody shipments across global distribution networks
• Validation and routine surveillance of ultra-low temperature (−80 °C) freezers and liquid nitrogen dewars in biobanks
• Temperature mapping studies for ISO 13485-certified medical device storage facilities
• Environmental qualification of cleanroom pass-through chambers and stability chambers per ICH Q5C
• Field-deployed logging for clinical trial sample transport (FDA Form 1572-compliant documentation available)
• Continuous cold chain verification for WHO prequalified vaccines under the COVAX Facility framework

FAQ

Is the C1-AGP-10 suitable for use inside liquid nitrogen vapor phase?

Yes—the device’s sensor interface and electronics are rated for sustained exposure to −196 °C vapor-phase environments when used with compatible cryo-probes; full operational validation data is available upon request.
Does the logger support 21 CFR Part 11-compliant electronic signatures?

The hardware itself does not generate signatures, but when paired with ColdChainIQ cloud software configured in “GxP Mode”, it fully supports audit trails, role-based e-signatures, and system validation documentation.
Can multiple C1-AGP-10 units be managed from a single dashboard?

Yes—ColdChainIQ supports fleet management of up to 10,000 concurrent loggers with centralized alerting, group configuration, and cross-device correlation analytics.
What is the calibration interval recommendation?

Annual calibration is recommended per ISO/IEC 17025 guidelines; Duling offers accredited on-site or return-to-factory calibration services with NIST-traceable certificates.
Is offline logging possible if network connectivity is lost?

Yes—the device stores up to 32,000 timestamped records internally and automatically resumes transmission once connectivity is restored, ensuring zero data loss.
