Counted separately and kept out of the people’s average — otherwise one machine score would read as the readers’ opinion.

The Smart Sensor ST8990 Multi Gas Monitor is the sort of handheld safety tool used by technicians who need to check for more than one gas at once. By our assessment, its real value is in combining multi-gas detection in a single portable unit, which is more practical than carrying separate meters for each task. The downside is the usual one for this category: sensors need care, calibration matters, and the device is only as trustworthy as its upkeep. In practice these monitors are about alarms, readings, and paying attention, not about comfort or glamour. It sits in the professional safety corner of the market, closer to workplace gas detection than to consumer gadgets, and that is exactly where it makes sense. The name itself already tells you it is a tool, not a toy, and 8990 is part of that catalogue name rather than a measurement.
