Introduction
A portable thermal imaging camera detects infrared radiation emitted or reflected by objects and converts it into a thermogram — a visible image showing surface temperature distribution. Unlike contact-based instruments, these cameras allow non-contact inspection of energised equipment, rotating machinery, structural surfaces, and high-temperature process zones without interrupting operations.
Tempsens offers the ThermEye series of handheld thermal imaging cameras, engineered for industrial-grade reliability across demanding field environments. The range spans resolution tiers from 256×192 to 640×512, temperature measurement from −20°C to +650°C, and includes models with auto-focus, manual focus, and focus-free designs — giving maintenance professionals a precise tool for predictive maintenance, fault detection, and process monitoring.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Portable Thermal Imaging Camera.
Point the camera at the target surface and allow a brief warm-up for detector stabilisation. Select the appropriate temperature range and colour palette for the inspection environment. Use the auto-tracking function to identify the highest and lowest temperature points on the scene. Use manual or automatic focus controls to achieve clear thermal imaging of an object. Capture thermograms for storage, then review them through InfraVIEW to obtain temperature measurements in Return on Investment (ROI), create trend graphs, and set alarm levels for out-of-norm conditions.
