Fourtec DaqPRO 5300 Eight-Channel Handheld Data Logger

Overview

The Fourtec DaqPRO 5300 is a rugged, battery-powered, handheld data acquisition and logging system engineered for field-deployable precision measurement across diverse industrial, environmental, and research applications. Built on a 16-bit analog-to-digital conversion architecture, it delivers high-resolution sampling across eight independently configurable input channels—enabling simultaneous monitoring of voltage, current, resistance-based temperature sensors (PT100, NTC), thermocouples (J, K, T types), pulse/frequency signals (Channel 1 only), and analog process signals (0–10 V, 0–50 mV, 0–24 mA). Its embedded real-time operating system supports autonomous operation without external PC dependency, making it suitable for unattended long-term deployments or rapid-response diagnostics in dynamic environments. Designed for traceability and operational integrity, the DaqPRO 5300 complies with CE and FCC electromagnetic compatibility and safety directives—ensuring reliable performance in regulated settings including ISO 17025-accredited laboratories, HVAC commissioning, and GLP-aligned environmental monitoring programs.

Key Features

• Eight-channel programmable analog input system with per-channel sensor-type selection (voltage, current, RTD, thermocouple, NTC, frequency/pulse)
• 16-bit A/D resolution ensuring sub-millivolt and sub-degree-Celsius measurement fidelity
• Sampling rate configurable from 1 sample/hour to 4,000 samples/second (single-channel burst mode)
• Onboard 512 KB non-volatile RAM for secure data retention during power loss or battery depletion
• High-contrast monochrome graphical LCD (128 × 64 pixels) supporting real-time waveform plotting, numeric readouts, tabular data views, and statistical overlays (min/max/avg)
• Integrated rechargeable 7.2 V NiMH battery providing up to 40 hours of continuous operation; also compatible with external 9–12 V DC input
• Compact, drop-resistant ABS enclosure (182 × 100 × 28 mm, 450 g) rated for operation in ambient temperatures from 0 °C to 50 °C
• USB 1.1 interface for configuration, firmware updates, and high-speed data offload via Fourtec’s proprietary DaqStudio software

Sample Compatibility & Compliance

The DaqPRO 5300 supports direct connection to standard industrial and scientific transducers without signal conditioning hardware. Its universal input design accommodates 2-, 3-, or 4-wire PT100 configurations, cold-junction compensation for thermocouples, linearization for NTC thermistors, and scalable current-loop inputs compliant with IEC 61000-4-5 surge immunity requirements. All measurements adhere to traceable calibration practices aligned with ISO/IEC 17025 clause 5.10; device firmware includes built-in self-test routines and timestamped calibration log entries. CE marking confirms conformity with the EU’s Electromagnetic Compatibility Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. While not FDA 21 CFR Part 11-certified out-of-the-box, audit-trail functionality—including user-access logs, configuration change history, and tamper-evident file hashing—is enabled via DaqStudio v4.2+ for GxP-relevant deployments.

Software & Data Management

DaqStudio software (Windows-compatible) provides full configuration, visualization, and post-processing capabilities. Users define channel parameters (scaling, filtering, alarm thresholds), schedule sampling profiles, and generate time-synchronized multi-parameter reports in CSV, Excel, or PDF formats. Raw binary files (.daq) are encrypted during transfer and include embedded metadata (device ID, firmware version, UTC timestamps, sensor calibration IDs). The software supports automated data archiving to network drives, email alerts on threshold violations, and batch export for integration into LIMS or SCADA platforms. For regulatory compliance, optional DaqStudio Audit Mode enables electronic signature capture, role-based access control, and immutable audit trails meeting ALCOA+ principles.

Applications

• Quality assurance testing of electronic assemblies and power supplies under thermal stress
• Continuous condition monitoring of motors, pumps, and HVAC chillers using vibration-correlated temperature and current signatures
• In-field validation of environmental chambers and stability storage units per ICH Q5C and USP
• Agricultural microclimate profiling—soil moisture correlation with air temperature/humidity at remote field stations
• Automotive ECU diagnostics and exhaust gas temperature mapping during road-load testing
• Pharmaceutical warehouse temperature mapping per WHO Technical Report Series No. 961 Annex 9
• Water quality parameter trending (pH, dissolved oxygen, conductivity) in municipal distribution networks
• Academic field research requiring portable, low-power, multi-sensor synchronization in ecological or geophysical studies

FAQ

Can the DaqPRO 5300 operate continuously while connected to external power?
Yes—the device automatically switches to external 9–12 V DC supply when connected, bypassing battery discharge and enabling indefinite runtime.
Is calibration certificate included with shipment?
A factory calibration report (traceable to NIST standards) is provided; ISO/IEC 17025-accredited calibration services are available upon request.
Does the unit support Modbus or other industrial protocols?
No—communication is limited to USB 1.1 for configuration and data retrieval; protocol translation requires external gateway hardware.
How is data integrity ensured during unexpected power loss?
All writes to internal RAM are atomic and checksum-verified; last valid sample set is preserved even during abrupt shutdown.
Are custom scaling equations supported for non-linear sensors?
Yes—user-defined polynomial or piecewise-linear scaling tables can be assigned per channel within DaqStudio.
