Predictive maintenance of electrical panels and substation equipment, where the camera is used every day in the field, calls for a light, impact-resistant handheld camera with visible-image fusion to locate the hot component. The TC4 and TC8 offer this with 160 × 120 (TC4) or 384 × 288 (TC8) detectors, NETD ≤ 0.06 °C at 30 °C, fusion with a 3 MP daylight camera on a 3.6-inch touchscreen and a 0.98 kg body that withstands 2 m drops, 25G shocks and 2G vibration, with IP54 sealing.
TC4 and TC8 key data
- Detectors: uncooled FPA microbolometer of 160 × 120 in the TC4 and 384 × 288 in the TC8, over the 8-14 µm band at 50/60 Hz.
- Optics: 25° × 19° field of view and manual focus with 0.1 m minimum distance; spatial resolution (IFOV) of 2.37 mrad in the TC4 and 1.37 mrad in the TC8.
- Sensitivity and accuracy: NETD ≤ 0.06 °C at 30 °C in both models; ±2 °C or ±2 % of reading, whichever is greater.
- Ranges: TC4 from −20 °C to +350 °C, expandable to 650 °C; TC8 from −20 °C to +650 °C, expandable to 1200 °C or 2000 °C.
- Analysis: up to 5 spots, 5 areas (maximum, minimum and average temperature) and 2 lines, profiles, isotherms, temperature difference and voice and colour alarms; emissivity from 0.01 to 1.0.
- Image: 3 MP daylight camera with dual LED fill lights, IR-daylight fusion on a 3.6-inch 640 × 480 TFT touchscreen, and 11 palettes.
- Ruggedness: 2 m drops, 25G shock (IEC 68-2-29), 2G vibration (IEC 68-2-6), IP54 and operation from −15 °C to +50 °C.
- In the field: 0.98 kg, 230 × 105 × 245 mm, Li-Ion battery for 3 h of continuous use, 8 GB micro SD expandable to 32 GB, 60 s voice notes and class 2 laser pointer (1 mW, 635 nm).
Advantages
Built to be dropped
New drop-resistant sensor technology withstands 2 m falls, 25G shocks (IEC 68-2-29) and 2G vibration (IEC 68-2-6), with IP54 sealing — under 1 kg in hand.
Fusion display
The thermal image and the 3 MP daylight photo fuse on the 3.6-inch touchscreen, and dual LED fill lights keep dark cabinets visible.
Two models, one platform
The TC4 (160 × 120) covers −20 °C to +350 °C, expandable to 650 °C; the TC8 (384 × 288) reaches +650 °C, expandable to 1200 °C or 2000 °C.
Analysis and alarms
Up to 5 spots, 5 areas and 2 lines with maximum, minimum and average values, profiles, isotherms, temperature difference and voice/colour alarms.
Connected in real time
Network transmission of picture and video, Bluetooth audio (headset/RS232) and mini-USB transfer of images and radiometric data.
Applications
- Predictive maintenance of electrical panels, lines and substation equipment.
- Industrial inspection and process control.
- Scientific research with real-time transmission.
About the product
TC4 and TC8 share an ergonomic handheld design with side-mount handrail, 1/4-inch tripod thread and a Li-Ion battery for 3 h of continuous use with automatic sleep and shut-down. Recording combines JPEG and H.264, both with original radiometric data, plus 60 s voice notes per image.
Storage on 8 GB micro SD (TF) card, expandable to 32 GB.

Frequently asked questions
Which rugged thermal camera is best for day-to-day electrical maintenance?
A light handheld camera rated against drops. The TC4 and TC8 weigh 0.98 kg, withstand 2 m drops, 25G shocks and 2G vibration with IP54 sealing, and their Li-Ion battery gives 3 h of continuous use.
Up to what temperature do the TC4 and TC8 measure?
The TC4 from −20 °C to +350 °C, expandable to 650 °C; the TC8 from −20 °C to +650 °C, expandable to 1200 °C or 2000 °C. Both measure with an accuracy of ±2 °C or ±2 % of reading.
What distinguishes the TC4 from the TC8?
The detector: 160 × 120 with 2.37 mrad in the TC4 and 384 × 288 with 1.37 mrad in the TC8, which also extends the temperature range up to 2000 °C as an option.
Does it survive a fall on site?
Yes. The series is rated for 2 m drops, 25G shocks and 2G vibration, with IP54 sealing.
How is audio handled?
Voice notes of up to 60 s attach to each image through the built-in microphone, and Bluetooth links a headset or RS232 for audio and data.
How are images transferred?
Via mini-USB with measurement data, video output or network transmission in real time.
