HIKMICRO G31 Thermal Camera – 384 × 288 IR Resolution

G31

The HIKMICRO G31 Handheld Thermography Camera is an advanced thermal imaging camera designed for professional temperature measurement, predictive maintenance, and fault detection across HVAC, electrical, mechanical, building, industrial, and maintenance applications.

With a 384 × 288 infrared detector and SuperIR image enhancement up to 768 × 576, the G31 delivers clear thermal detail for identifying overheating components, insulation failures, energy loss, mechanical wear, electrical faults, and abnormal temperature conditions.

The G31 combines multiple focus options, a 50 Hz image frequency, an 8 MP visual camera, a large 4.3" touchscreen, radiometric image capture, advanced measurement tools, and a wide temperature range up to 650°C, making it a powerful inspection tool for demanding professional environments.

Designed for field efficiency, the G31 supports thermal, visual, fusion, picture-in-picture, and blending image modes, along with Wi-Fi, Bluetooth, USB Type-C, HDMI, GPS, compass, and annotation functions to support accurate reporting and streamlined inspection workflows.

Built with rugged IP54 protection, 2 m drop resistance, and an interchangeable rechargeable battery system, the HIKMICRO G31 is suitable for daily use by professional technicians, engineers, and maintenance teams who require reliable thermal imaging performance on site.
