Overview
The AZ8829 Temperature & Humidity Data Logger is a compact, field-deployable environmental monitoring instrument engineered for long-term, unattended recording of ambient temperature and relative humidity. Based on high-stability capacitive humidity sensing and precision NTC thermistor technology, the device complies with fundamental metrological principles defined in ISO 17025-accredited calibration practices for environmental sensors. Its robust IP65-rated enclosure ensures reliable operation in industrial storage facilities, pharmaceutical cold-chain validation environments, museum climate control zones, and logistics transit monitoring—where exposure to dust, condensation, or mechanical handling is routine. With a sampling interval programmable from 1 second to 2 hours and non-volatile memory retaining up to 16,000 timestamped records, the AZ8829 supports both high-resolution short-duration studies and extended baseline stability assessments over weeks or months.
Key Features
- IP65-rated rugged housing—resistant to water ingress, impact, and surface abrasion for deployment in demanding physical environments
- Non-volatile flash memory: all stored data retained during battery replacement or power loss—no risk of record corruption or gap formation
- Dual-color status LED: red illumination indicates exceedance of user-defined upper/lower alarm thresholds; yellow confirms active data acquisition
- Configurable sampling intervals—from 1 second (for transient thermal event capture) to 2 hours (for low-power multi-week logging)
- Integrated 4-digit LCD display showing real-time temperature (°C/°F), relative humidity (%RH), and alarm status flags (AL-H/AL-L)
- Multiple communication interfaces: standard RS232 serial port (9600 baud) for direct PC connection and optional IRDA support for infrared printing
- Low-power architecture: 3.6 V lithium primary battery (½AA form factor, 1.2 Ah capacity) enables typical operational lifetime of ≥2 years at 10-minute logging intervals
Sample Compatibility & Compliance
The AZ8829 is designed for ambient air measurement only and is not intended for immersion, pressurized gas, or corrosive vapor environments. It meets IEC 60529 for IP65 ingress protection and conforms to RoHS Directive 2011/65/EU for hazardous substance restriction. While not certified to FDA 21 CFR Part 11 or ISO 13485, its data integrity features—including time-stamped immutable records, battery-fail-safe memory retention, and deterministic RS232 protocol—support alignment with GLP and GMP documentation requirements when used within validated procedures. Calibration traceability follows NIST-traceable reference standards per manufacturer’s service documentation.
Software & Data Management
The included Windows-compatible software (v3.x, USB 1.1 and legacy RS232 supported) provides full configuration, download, visualization, and export functionality. Users may define custom alarm limits, set sampling schedules, and assign descriptive session labels prior to field deployment. Downloaded datasets are exportable as CSV or Excel (.xlsx) files for integration into LIMS, statistical process control (SPC) platforms, or audit-ready PDF reports. The software implements basic trend analysis, min/max/average calculation per channel, and time-synchronized overlay of temperature and humidity traces—enabling correlation assessment critical for dew point estimation and condensation risk modeling.
Applications
- Pharmaceutical warehouse and transport validation (per WHO TRS 961 Annex 9 and EU GDP guidelines)
- Museum and archive environmental monitoring for preservation of hygroscopic artifacts
- Food storage facility temperature mapping and HACCP compliance verification
- Electronics manufacturing cleanroom ambient stability tracking
- Academic laboratory environmental baseline characterization for material aging studies
- Building HVAC system performance evaluation and energy efficiency benchmarking
FAQ
Does the AZ8829 support real-time data streaming?
No—it operates in standalone logging mode only. Data is retrieved post-deployment via RS232 or IRDA; no continuous live transmission capability is provided.
Can the device be calibrated in-house?
Field calibration is not supported. Users must return the unit to an authorized service center for NIST-traceable recalibration using certified humidity generators and dry-well temperature standards.
Is the software compatible with macOS or Linux?
The official configuration and download software is Windows-only (Windows 7 through 11, 32/64-bit). Command-line or third-party drivers for cross-platform access are not supplied or validated.
What happens if the battery dies mid-recording?
All 16,000 records remain fully intact in non-volatile memory. Upon battery replacement, logging resumes automatically from the last recorded timestamp without data loss or sequence disruption.
Does the AZ8829 meet ATEX or IECEx certification for hazardous areas?
No—it carries no intrinsic safety certification and must not be deployed in explosive atmospheres classified under Directive 2014/34/EU or IEC 60079 standards.
