Our take on the GJX 3.2Inch LCD Infrared Thermal Imager Sensor Thermometer Thermal Imaging Camera Handheld Multi-function Thermal Imager

The GJX is a handheld thermal imager built around the MLX90640 infrared sensor and a 3.2-inch 320x240 LCD. It shows a live thermal image alongside numeric readouts and tracks the highest, lowest and center-point temperatures. It runs up to 10 hours on a USB-C rechargeable lithium battery and stores about 100 images on internal memory for transfer to a computer or phone. It suits home inspectors, electricians and hobbyists who want a basic thermal view without paying for a big-brand camera. The 8Hz refresh and 40 to 300°C range are modest next to higher-end imagers, which refresh faster and read lower temperatures.

About the GJX 3.2Inch LCD Infrared Thermal Imager Sensor Thermometer Thermal Imaging Camera Handheld Multi-function Thermal Imager

This is a handheld thermal imager with a 3.2-inch TFT display and an MLX90640 infrared sensor. It shows an infrared image together with temperature values. The screen displays and tracks the highest, lowest and center-point temperatures.

The shell is made of FR4 epoxy board to protect the internal components. The unit is compact and lightweight. A rechargeable lithium battery powers it and charges over USB-C, and it can be used while charging. Built-in flash storage holds 100 images, which you can view and copy on a computer or phone through a data cable.

It works on the blackbody radiation law: the hotter an object is, the more infrared radiation it emits. The chip processes this data and shows the temperature on the screen. Uses include non-contact temperature measurement, intrusion detection, human body temperature detection, building environment temperature control, automotive air conditioning control, microwave oven and oven temperature detection, and industrial parts temperature monitoring.

Questions and answers

What temperature range does it measure?
It reads targets from 40 to 300°C. Surfaces below 40°C, including most room-temperature objects and people, fall outside its range.
How smooth is the live image?
The display refreshes at 8Hz, so the thermal picture updates about eight times a second. That is fine for steady targets but looks choppy when you pan across a scene.
Can I save and share the images?
Yes. Internal memory holds about 100 images, and you copy them to a computer or phone over a data cable.
How long does the battery last?
Up to 10 hours per charge. It charges over USB-C and can keep working while plugged in.
What sensor does it use?
An MLX90640ESF-BAB infrared sensor. It is a low-resolution array, so the thermal image is blockier than cameras with higher-resolution detectors.
Is it good for finding air leaks or fever screening?
It works for spotting hot and cold spots on walls, ducts and equipment. It cannot screen for fever because its range starts at 40°C.
