Advanced Dual-Lens Specifications of the MTV256 PRO
Engineered for precision, the MTV256 PRO features a high-sensitivity 192×256 infrared sensor with a spectral range of 8~14um and a 3.2mm lens. This is paired with a 720P visual light camera (55°x83° FOV) to give professionals complete visual context. The device accurately measures a wide temperature range from -20°C up to 400°C with an accuracy of ±2°C or ±2%.
With a fast 25Hz frequency and a thermal sensitivity (NETD) of 70mK@25°C, it delivers incredibly smooth thermal video. Users have total control over their diagnostics with dynamic measurement options that track the highest, lowest, central, and zone temperatures. You can also customize your display using 8 distinct color palettes: Iron red, white hot, black hot, rainbow, red hot, high contrast, green hot, and volcano.
Storage, Battery, and Design of the MTV_256 PRO
Built for demanding job sites, the MTV_256 PRO operates reliably in temperatures ranging from -10°C to +60°C. Despite its rugged build, it is highly portable, weighing just 310g with dimensions of 115mm x 170mm x 300mm.
