A maritime-style brass thermometer and hygrometer housed in a circular porthole-form case. The solid brass body features a hinged glazed cover secured by two functional swing-bolt wing nuts. The outer mounting flange is pierced with three apertures for wall mounting. The silvered dial comprises two semi-circular scales with slender black indicator needles. The upper scale is marked THERMO °C and calibrated from -20 to 50. The lower scale is marked HYGRO % rel. and calibrated from 20 to 100. The instrument is designed for internal use to monitor temperature and relative humidity. No maker’s marks are visible on the dial or the reverse.
