Measurement and safety notes

• Thermal readings depend on emissivity, reflections, distance, target size and environmental conditions.
• Critical readings should be confirmed with an appropriate calibrated contact instrument.
• UTi260M and UTi261M list a 20°C–50°C human-body measurement mode, but these products are not medical diagnostic devices.
• Do not use a mobile thermal camera for safety-critical decisions without appropriate verification.

Frequently asked questions

Which UNI-T UTi model works with Android?

UTi120Mobile, UTi256M, UTi260M and UTi261M are the Android variants listed on this page. Confirm the connector, Android version and compatible app before ordering.

Which model works with iPhone or iOS?

UTi120MS is the listed iPhone/iOS version. Do not select an Android model solely because its plug looks similar to your iPhone port.

Which models provide 256 × 192 thermal resolution?

UTi256M, UTi260M and UTi261M provide 256 × 192 infrared resolution. UTi120Mobile and UTi120MS use 120 × 90 resolution.

Which model measures the highest temperature?

UTi260M has the widest listed range at -20°C to 550°C. UTi261M is listed to 450°C, the 120-series models to 400°C, and UTi256M to 200°C.

Can the camera record photos and videos?

The compatible mobile app supports thermal image and video capture. Available functions can vary by model, phone and app version.

Why can readings differ from the actual surface temperature?

Infrared measurement is affected by emissivity, reflective surfaces, viewing distance, target size and ambient conditions. Adjust emissivity for the target material and confirm critical readings separately.
