Observations
A VARIANT OF THE 875i-1 WITH A HUMIDITY PROBE INCLUDED, the only documented difference between the two models according to the distributor: same 160 × 120 sensor, same NETD, same measurement range. Another example of range segmentation via a single accessory rather than a technical upgrade, a pattern already seen on HIKMICRO's B and SP series as well as on the B21L and B21LS in this comparison.
Also marked as discontinued by the distributor, with the same recommended replacement model as the 875i-1.
