Fast Reading Capture

A check squeezed between other tasks has to settle in seconds, not minutes.

Repeatable Measurements

Two readings a minute apart should agree, or neither one tells you anything.

Wipe-Clean Outer Surfaces

Shared use across people means the housing gets cleaned between every check.

Exportable Record Files

A reading is more useful when it can be sent on to whoever asked for it.

Pocket-Carry Portability

Spot checks happen wherever the person is, not at a desk with a bag nearby.
