Buyer risk reduced: Helps reduce overheating, power instability, unexpected shutdowns, charging failures, and reliability issues in enclosed cabinets, vehicles, outdoor sites, and high-load environments.

🔌

I/O & Expansion

Tests key interfaces and expansion options such as USB, LAN, COM, HDMI, DP, VGA, GPIO, audio, DC input, M.2, PCIe, SIM, WiFi, 4G/5G, PoE, and storage modules based on product configuration.
Buyer risk reduced: Helps ensure stable connection with PLCs, cameras, sensors, barcode scanners, HMI systems, industrial networks, expansion cards, and project-specific peripheral devices.

🏗️

Rugged Durability

Checks rugged reliability for selected models, including waterproof protection, dustproof sealing, drop resistance, vibration resistance, shock resistance, port protection, housing strength, and mobile-use durability.
Buyer risk reduced: Helps reduce damage risk in field service, warehouse logistics, vehicle-mounted operation, outdoor inspection, public safety, construction, energy, and other harsh working environments.

🖥️

Display & Touch

Inspects display quality, brightness, dead pixels, touch response, multi-touch performance, touchscreen accuracy, outdoor readability, and glove or wet-hand touch support when available on selected models.
Buyer risk reduced: Helps improve field usability, operator accuracy, HMI interaction, outdoor visibility, and stable touch operation in factories, vehicles, warehouses, and mobile work scenarios.

📦

Final QC & Logistics

Reviews final product configuration, operating system, appearance, serial number, labels, accessories, power adapters, packaging protection, order information, and shipment readiness before delivery.
Buyer risk reduced: Helps reduce configuration mismatch, missing accessories, labeling errors, shipment damage, batch inconsistency, and delivery issues before products reach the customer.

Why Testing Matters for Industrial Computers？

Industrial computers are often deployed in factories, vehicles, warehouses, energy sites, automation systems, and outdoor environments. A small hardware failure may cause production downtime, communication errors, or maintenance costs.

That is why SINSMART focuses on functional testing, stability verification, interface inspection, rugged reliability checks, and final shipment inspection before delivery.

Factory Automation: In factory automation, industrial PCs may connect with PLCs, sensors, barcode scanners, cameras, and MES/SCADA systems. I/O instability or system crashes can interrupt production lines and increase maintenance costs.
Vehicle & Logistics: In forklifts, trucks, AGV/AMR systems, and warehouse operations, computers may face vibration, dust, battery switching, unstable power input, and frequent movement.
Outdoor & Harsh Environments: In outdoor inspection, energy sites, ports, and field service scenarios, rugged devices may need sunlight readability, sealed ports, drop resistance, and reliable wireless communication.
Machine Vision & Edge AI: For machine vision and edge AI projects, thermal stability, GPU expansion, storage speed, LAN performance, and long-term operation are critical to avoid data loss or processing interruption.
