Number of the sensor's measurement points, shown to the catalog's scale.
The largest sensor in the database has 327 680 points.
Published by the manufacturer
The best combined NETD and frame rate of the entire HIKMICRO M series. 30 mK at 50 Hz, versus 35 to 40 mK and 25 Hz for the M10, M11, M20, and M30 in the same range according to the manufacturer's own comparison table. A clear example of an internal lineup where the top model prioritizes sensitivity over resolution, since the 384 × 288 sensor remains the same as the M30's.

Observations
Like the entire already-covered G series in this comparison, HIKMICRO publishes neither weight, nor dimensions, nor IP rating, nor pixel pitch for this professional range, even though its measurement performance ranks among the best in the catalog across all brands.
Replaceable battery, unlike most of the built-in-battery devices in this comparison.
Neither emissivity setting nor reflected-temperature correction are documented in the sources consulted, to be checked against the user manual as was done for the B series.
