Observations
A 256 × 192 SENSOR WITH NO INTERPOLATION CLAIMED AT ALL, like the already-covered TOOLTOP T7 and HIKMICRO E1L in this comparison. An advertised IP65 rating, identical to the already-documented UNI-T UTi260B and UNI-T UTi720A, a level above the IP54 typical of this price segment.
A 5000 mAh battery, one of the largest capacities in the entire catalog for a device of this format, even surpassing some far pricier professional devices.
An advertised accuracy of ±3°C, wider than most direct competitors at the same resolution (±2°C at HIKMICRO, InfiRay, or Thermal Master), a trade-off consistent with the brand's price positioning.
