Portable Field Monitor
A sunlight-readable instrument for logging temperature and air quality away from mains power.
Built for glare and dust
The monitor records ambient temperature, humidity, and particulate levels to a removable card. A hooded monochrome display remains legible in full sun, while three oversized controls work with gloves.
The enclosure is a two-part print with a replaceable gasket. No cloud account or radio link is required; the data remains on the instrument until the card is removed.
