H21Pro+ Handheld Thermography Camera
Industrial Thermography | Fault Detection | Professional Thermal Imaging
Core capabilities for field inspection
The H21Pro+ combines non-contact thermography, temperature measurement and field-ready documentation to help locate abnormal heat quickly and support follow-up analysis.
Clear thermal detail
A 256 × 192 detector with a 25 Hz frame rate helps reveal temperature distribution across the target.
NETD <50 mk (@25 °C,F#=1.0)Wide inspection coverage
The -20 °C ～550 °C temperature range supports routine equipment inspection, fault location and preventive maintenance.
Accuracy ±2 °C or of reading ±2%(whichever is greater)Built for field observation
A 37.2° × 50.0° field of view and a focus configuration of fixed focus balance scene coverage with target detail.
IR resolution 256 × 192Information at a glance
The 3.2inch LCD display (480 × 640) display keeps thermal imagery and measurement data easy to review on site.
Measurement tools: 6 measurement spots (center spot, maximum temperature, minimum temperature, 3custom spots)Ready for industrial sites
IP54 protection, 2m drop resistance and a weight of 380 g (including battery) support mobile field use.
Dimensions 221.7 mm × 73.5 mm × 123.8 mmCapture, transfer and analyze
Storage: 16GB eMMC (usable storage is lower than16GB); Wi-Fi: Supported; 4G: Not supported.
Battery runtime >6 h@25 °CSee the full temperature picture at a glance
The 37.2° × 50.0° and 256 × 192 infrared detector bring the thermal distribution and measurement results into one view, helping inspectors identify hot spots, cold spots and abnormal areas quickly.
See temperature distribution and locate anomalies quickly
The 256 × 192 infrared detector and 37.2° × 50.0° field of view deliver non-contact measurement across -20 °C ～550 °C.
Turn field temperatures into actionable information
Rated accuracy is ±2 °C or of reading ±2%(whichever is greater). Measurement tools, color palettes and alarms help confirm hot spots, cold spots and selected areas.
Designed for sustained inspection and follow-up analysis
The camera provides 16GB eMMC (usable storage is lower than16GB) storage and >6 h@25 °C battery runtime, together with IP54 protection and 2m drop resistance.
