Overview
The Duling C1-AGS-10(4G) is a compact, standalone temperature and humidity data logger engineered for continuous environmental monitoring in cold chain logistics, pharmaceutical storage, vaccine transport, and laboratory sample preservation. It operates on the principle of digital sensor-based acquisition—integrating a calibrated capacitive humidity sensor and a high-stability NTC thermistor—to capture ambient thermal and hygrometric conditions at user-defined intervals. Data is processed onboard, displayed locally on an integrated LCD screen, and transmitted securely via embedded 4G LTE connectivity to a cloud-based platform compliant with TLS 1.2 encryption. Unlike USB- or Bluetooth-dependent loggers, the C1-AGS-10(4G) functions autonomously in remote or infrastructure-limited environments—eliminating dependency on local Wi-Fi networks or gateway hardware. Its design adheres to the functional requirements outlined in ISO 14644-3 (cleanroom environmental monitoring), WHO Technical Report Series No. 961 (cold chain validation), and EU GDP Annex 9 (temperature-controlled transport).
Key Features
- Integrated dual-parameter sensing: Simultaneous acquisition of temperature (−40 °C to +100 °C) and relative humidity (0–100 %RH) with traceable calibration.
- High-resolution local display: Backlit monochrome LCD showing real-time values, battery status, signal strength, and logging interval—enabling immediate visual verification without external software.
- Configurable logging interval: Adjustable sampling frequency from 1 to 10 minutes per cycle, supporting both high-fidelity transient analysis and extended battery life during long-haul shipments.
- Embedded 4G LTE modem: Supports CAT-M1/NB-IoT fallback; compatible with major global mobile network operators; automatic reconnection after signal loss.
- Robust enclosure: IP65-rated housing with reinforced ABS+PC casing, designed to withstand vibration, condensation, and temperature shock typical in refrigerated trucks and walk-in cold rooms.
- Extended operational autonomy: Powered by a replaceable 3.6 V lithium-thionyl chloride (Li-SOCl₂) battery rated for ≥12 months at 10-minute intervals under typical operating conditions (25 °C, 50 %RH).
Sample Compatibility & Compliance
The C1-AGS-10(4G) is optimized for monitoring ambient air in enclosed transport containers (e.g., refrigerated vans, insulated shipping boxes), warehouse zones, and controlled storage cabinets. It interfaces exclusively with standard 2-wire or 3-wire analog (0–3 V or 4–20 mA) or digital (I²C/One-Wire)温湿度 sensors—though the base unit ships with one pre-calibrated external probe. The device complies with electromagnetic compatibility standards IEC 61326-1 (industrial environment) and meets RoHS Directive 2011/65/EU. Its measurement uncertainty budget aligns with ISO/IEC 17025:2017 clause 7.6.3 for in-field calibration traceability when used with certified reference sensors. While not intrinsically safe, it is suitable for non-hazardous Zone 3 environments per IEC 60079-0.
Software & Data Management
Data is uploaded to Duling’s secure cloud platform (accessible via web browser or dedicated iOS/Android application), where users configure alert thresholds (SMS/email/push notifications), generate PDF audit reports, and export CSV/Excel datasets with UTC timestamps. The platform supports role-based access control (RBAC), full audit trail (including user login, configuration changes, and alarm acknowledgments), and exportable metadata required for FDA 21 CFR Part 11 compliance—including electronic signatures, system-generated timestamps, and immutable record retention. Raw data files include CRC-16 checksums for integrity verification; historical logs are retained for ≥36 months unless manually purged.
Applications
- Cold chain validation for mRNA vaccines, biologics, and plasma-derived therapeutics during distribution.
- Real-time monitoring of temperature excursions in GMP-compliant storage areas (e.g., stability chambers, quarantine zones).
- Compliance documentation for IATA Perishable Cargo Regulations (PCR) and USP Cold Chain Management.
- Environmental qualification of transport packaging per ISTA 7E and ASTM D3103.
- Baseline ambient condition logging in GLP-regulated animal facilities and tissue culture labs.
FAQ
Does the C1-AGS-10(4G) support external sensor expansion beyond one channel?
No—the device is configured for a single external温湿度 sensor input. Multi-channel capability refers to its internal firmware architecture supporting future firmware-upgradable sensor modules; current hardware supports only one analog/digital probe interface.
Is calibration certificate included with shipment?
A factory calibration report (traceable to NIM China) is provided with each unit. NIST-traceable calibration certificates are available upon request at additional cost and require lead time.
Can the device operate offline and buffer data during 4G outages?
Yes—it buffers up to 32,768 timestamped records internally. Once connectivity resumes, all queued data is transmitted in chronological order with no loss or duplication.
What is the maximum allowable operating altitude?
The unit is rated for operation up to 3,000 meters above sea level, with compensated humidity readings per ISO 11784.
Is firmware update supported over-the-air (OTA)?
Yes—secure OTA updates are delivered via the cloud platform and applied automatically during idle periods, preserving all configuration and historical data.
