Guide Manuals & User Guides

Qhia Sensmart (Wuhan Guide Sensmart Tech Co., Ltd.) is a specialized manufacturer of infrared thermal imaging products and a subsidiary of the Guide Infrared Group. Founded with a focus on bringing thermal technology to civilian markets, the company produces high-performance thermal cameras used in industrial inspection, power line maintenance, firefighting, and outdoor law enforcement.

The brand's portfolio features widely used devices such as the guide ZC series thiab TD series handheld thermal imagers. These products combine advanced infrared detectors with user-friendly designs to offer precise temperature measurement and clear imaging in low-visibility conditions.

• How should I clean the lens of my Guide thermal camera?

  Avoid touching the lens with your hands, as sweat can corrode the optical coating. If the lens is dirty, carefully wipe it using professional optical lens paper.

• What are the charging precautions for Guide thermal batteries?

  Charge the battery strictly according to the user manual instructions. Do not charge near high-temperature sources or fire. If the battery leaks or emits an odor, stop using it immediately.

• Can I use my thermal imager in the rain?

  While many Guide thermal cameras are ruggedized, you should check the IP rating in your specific manual. Generally, avoid exposing the device to heavy moisture or water splashes, and keep the lens covered when not in use.

• Why is the temperature measurement inaccurate?

  Inaccurate readings can occur if the camera is not focused correctly, if the target is reflective, or if the emissivity setting does not match the material being measured. Ensure the device is calibrated and the correct parameters are set.

• How do I perform a non-uniformity correction (NUC) or calibration?

  Many models allow you to perform a manual calibration (often by short-pressing the power button or a specific 'C' key) to refresh the image and remove ghosting artifacts.
