High-precision uncooled focal plane array devices designed for industrial maintenance, power inspection, and thermal analysis.
Shenzhen Dianyang Technology Co., Ltd. is a premier subsidiary of VHD (Shenzhen VHD Technology Co., Ltd.), a publicly listed enterprise on the Shenzhen Stock Exchange. This strategic corporate affiliation grants Dianyang direct access to VHD’s state-of-the-art optical-electronic R&D platforms, ultra-precision automated manufacturing systems, and rigorous tier-1 quality control standards—enabling us to produce non-contact radiometric thermal imaging systems of far superior consistency, repeatability, and endurance compared to standard industry offerings.
As a specialized global OEM/ODM manufacturer, we develop advanced infrared thermal cameras, smartphone radiometric attachments, optical-thermal analyzers, and specialized long-range thermography telescopes. Our mission is to democratize high-resolution thermal vision for maintenance technicians, electrical engineers, diagnostic auditors, and outdoor specialists globally.
The non-contact temperature measurement industry has undergone a radical transformation over the past decade. Traditional spot infrared thermometers (single-point IR pyrometers) are rapidly being superseded by fully radiometric Imaging IR Thermometers. While single-point pyrometers report a averaged temperature value across a defined spot ratio, imaging IR thermometers utilize uncooled Focal Plane Array (FPA) microbolometers to capture thousands to hundreds of thousands of discrete temperature points simultaneously.
This transition from single-point pyrometry to multi-pixel thermal radiometry allows inspectors to instantaneously visualize thermal anomalies, identifying friction points, phase imbalances, insulation voids, and structural thermal leaks that single-spot devices inevitably miss. Modern thermal thermometry integrates key technological vectors:
Leveraging Vanadium Oxide (VOx) sensors providing low Noise Equivalent Temperature Difference (NETD < 40mK), ensuring subtle thermal gradients are clearly rendered even in low thermal contrast environments.
Combining visible light optics with far-infrared spectral streams via proprietary algorithm fusion (MSX/Dual-Vision overlay), providing sharp physical edge details over raw thermal maps.
Incorporating on-device automated hot/cold point tracking, automatic isotherm mapping, and predictive failure alerts for industrial automated inspection lines.
When global industrial distributors, EPC contractors, and OEM brand partners source imaging IR thermometers, their purchasing decisions are governed by long-term total cost of ownership (TCO) and rigorous engineering parameters rather than superficial pricing. Procurement managers focus heavily on the following technical indicators:
Situated in Shenzhen—the hardware capital of the world—Dianyang Technology encapsulates the core advantages of China Industry 4.0 integrated supply chains. By capitalizing on parent enterprise VHD's massive manufacturing footprint, Dianyang operates automated Surface Mount Technology (SMT) lines, high-precision optical collimation labs, and fully automated blackbody temperature calibration tunnels.
Our dedicated engineering team applies Design for Manufacturing (DFM), Design for Testability (DFT), thermal physics simulation, and EMC pre-compliance analysis to optimize product stability and accelerate customized development cycles. We empower global brand partners by supporting complete certification processes across all target markets:
To assist enterprise buyers in selecting the exact thermography architecture for their market segment, the following operational matrix summarizes key technical performance parameters across our primary product lines:
| Series Model | Thermal Resolution | Temp Measurement Range | Spectral / Sensitivity | Primary Application Focus |
|---|---|---|---|---|
| DP-09D Series | 96 × 96 pixels | -20°C to 300°C | 8-14μm / NETD < 50mK | Compact HVAC inspection, entry-level electrician tools |
| DP-12D / 12DV Series | 120 × 90 pixels | -20°C to 550°C | 8-14μm / NETD < 45mK | Building diagnostics, electrical panel auditing, dual-light optical overlay |
| DP-25D / 25DR Series | 256 × 192 / 512 × 384 (Interp.) | -20°C to 550°C | 8-14μm / NETD < 40mK | Industrial predictive maintenance, mechanical bearing monitoring |
| DP-64D Series | 640 × 512 pixels | -20°C to 1200°C (Ultra High) | 8-14μm / NETD < 35mK | Heavy metallurgy, power grid substations, high-temperature furnace research |
| H2FB / H2F6B Series | 256 × 192 pixels | -20°C to 150°C / 550°C | Smartphone USB-C / iOS Direct | Ultra-portable field inspections, mobile thermal app analytics |
High-voltage switchgears, transformers, cable terminations, and busbars develop localized thermal anomalies prior to catastrophic dielectric breakdown. Using high-resolution models like the DP-64D (-20°C to 1200°C), utility engineers identify micro-ohm resistance build-up from safe distances.
Overheated motor bearings, misaligned drive belts, degraded pumps, and overloaded circuit breakers cause costly un-planned factory downtime. Continuous thermographic monitoring pinpoints mechanical friction and electrical overload before downtime occurs.
Infrared thermography non-destructively reveals building insulation gaps, thermal bridging, hidden roof moisture ingress, and HVAC ducting leakage, allowing facility managers to drastically reduce carbon footprint and HVAC operating expenses.
In Solar Photovoltaic (PV) installations, cracked cells or bypassed diodes lead to severe hot-spot degradation. In Electric Vehicle (EV) battery R&D, real-time thermal analysis maps heat dissipation during high-rate charging and discharging cycles.

Dianyang Technology is an official subsidiary of VHD (Shenzhen VHD Technology Co., Ltd.), a Shenzhen Stock Exchange listed company. This backing grants us access to capital-intensive R&D platforms, high-precision automated manufacturing facilities, and stringent quality assurance systems that standard suppliers cannot match, ensuring unmatched batch-to-batch consistency and long-term supply stability.
A spot IR thermometer measures the average temperature of a single region based on its distance-to-spot ratio. An Imaging IR Thermometer uses an array of thousands of thermal sensor pixels (microbolometers) to generate a complete visual temperature map, enabling instantaneous detection of localized hot spots, thermal leaks, and complex electrical anomalies across an entire surface.
We provide full-stack turn-key OEM/ODM services including industrial casing design, custom housing color schemes, private label branding, customized firmware menus, tailored radiometric temperature analysis PC software, mobile app development (iOS/Android SDKs), and specialized optical lens configurations.
Every single thermal unit manufactured at Dianyang undergoes rigorous multi-point blackbody calibration across its full operating thermal envelope (-20°C to 550°C or up to 1200°C). We utilize Design for Testability (DFT) and automated environmental thermal chambers to guarantee our rated accuracy of ±2°C or ±2% of reading.
