LESHI GIR310 High-Resolution Handheld Infrared Thermal Imaging Camera

Overview

The LESHI GIR310 is a high-resolution handheld infrared thermal imaging camera engineered for precision thermographic analysis in industrial, infrastructure, and research environments. Operating in the long-wave infrared (LWIR) spectral band (8–14 µm), it leverages an uncooled microbolometer detector array to capture radiometric temperature data without cryogenic or thermoelectric cooling—enabling rapid deployment, low power consumption, and extended field operation. Unlike cooled photon detectors, the uncooled architecture ensures mechanical robustness, reduced maintenance intervals, and stable calibration over time under ambient thermal cycling. The GIR310 delivers calibrated thermal imagery at native spatial resolution optimized for identification of sub-degree thermal anomalies across large surface areas, making it particularly suited for condition-based monitoring where repeatability, portability, and operational continuity are critical.

Key Features

• High-resolution thermal imaging core with native detector pixel pitch supporting detailed spatial discrimination of thermal gradients
• Adjustable dual-band fusion mode: seamlessly overlays visible-light and LWIR imagery for contextual interpretation and precise anomaly localization
• Integrated high-brightness OLED viewfinder with real-time radiometric rendering and emissivity-compensated temperature mapping
• Non-contact radiometric measurement capability with configurable measurement parameters—including spot, area, isotherm, and delta-T analysis modes
• Onboard Wi-Fi 5 (802.11ac) module enabling secure, low-latency streaming of live thermal video and synchronized metadata to Windows/Linux workstations or iOS/Android tablets
• Ruggedized ergonomic housing rated IP54 for dust and water resistance, compliant with MIL-STD-810G for shock and vibration tolerance during field use
• USB-C interface supporting high-speed bulk transfer of radiometric JPEG (.JPG + embedded .CSV metadata) and proprietary .IRB project files

Sample Compatibility & Compliance

The GIR310 is designed for non-destructive, non-invasive surface temperature assessment across electrically active equipment (e.g., switchgear, transformers, motor windings), building envelope components (insulation gaps, thermal bridging, moisture ingress), and mechanical systems (bearings, couplings, steam traps). It complies with ISO 18436-7:2014 for thermographic personnel qualification support and aligns with ASTM E1934-19 guidelines for qualitative and quantitative infrared inspection procedures. While not certified for safety-critical process control or medical diagnostics, its radiometric accuracy and traceable calibration protocol meet requirements for ISO/IEC 17025-accredited laboratories performing preventive maintenance audits. Device firmware supports user-defined emissivity tables and reflected apparent temperature compensation per surface material class.

Software & Data Management

The GIR310 operates with LESHI’s IRVision Pro desktop application (Windows 10/11, 64-bit), which provides full radiometric post-processing, emissivity correction, multi-image comparison, and automated report generation in PDF/HTML formats. All captured frames retain embedded calibration coefficients, lens distortion maps, and environmental metadata (ambient temperature, humidity, distance, relative humidity)—enabling retrospective recalibration and audit-ready documentation. The software supports FDA 21 CFR Part 11-compliant user access controls, electronic signatures, and immutable audit trails when deployed in regulated QA/QC workflows. Cloud synchronization via optional LESHI CloudLink service enables centralized fleet management, version-controlled firmware updates, and cross-site thermal trend analysis.

Applications

• Predictive maintenance programs for electrical distribution networks, including arc-flash risk screening and load imbalance detection
• Building energy auditing per ASHRAE Guideline 2-2018 and ISO 50002:2014 standards
• Mechanical integrity verification of rotating equipment, heat exchangers, and refractory linings
• R&D thermal profiling of PCB assemblies, battery modules, and thermal interface materials
• FACILITY-level commissioning validation of HVAC zoning, duct leakage, and radiant floor heating uniformity
• Post-disaster structural assessment for concealed water damage or fire-damaged insulation integrity

FAQ

Does the GIR310 provide quantitative temperature measurements traceable to NIST standards?
Yes—each unit ships with a factory calibration certificate referencing NIST-traceable blackbody sources. Field recalibration is supported using optional portable reference calibrators (e.g., Mikron M390 series).
Can the device operate continuously for more than two hours on a single charge?
With the standard 7.4 V / 4200 mAh Li-ion battery, runtime exceeds 2.8 hours under typical survey conditions (screen brightness 60%, Wi-Fi active, 30 Hz capture). Extended-life battery packs are available as accessories.
Is raw thermal data export supported for third-party analysis in MATLAB or Python?
Yes—radiometric pixel arrays can be exported as 16-bit TIFF or CSV matrices via IRVision Pro; Python SDK and MATLAB-compatible .mat wrappers are provided in the Developer Resource Kit.
What is the minimum focus distance and spatial resolution at 1 meter?
Minimum focus distance is 0.3 m; instantaneous field of view (IFOV) is 1.3 mrad, yielding ~1.3 mm spatial resolution at 1 m standoff distance with standard 24° lens.
Does the GIR310 support integration into existing CMMS or EAM platforms?
Via RESTful API and OPC UA server module (optional license), the GIR310 enables direct thermal event logging into IBM Maximo, SAP PM, or UpKeep systems using standardized JSON payloads and alarm-triggered image capture.
