Core capabilities for field inspection
The H21ProS+(AI) 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: 8 measurement spots (center spot, maximum temperature, minimum temperature, 5custom 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 °CSmarter scene adaptation for faster decisions
The 256 × 192 infrared detector and 37.2° × 50.0° present temperature distribution across -20 °C ～550 °C, with an inspection workflow optimized to make anomalies easier to recognize.
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.
