The IMN brass thermohygrometer with a 95 mm dial is designed to provide accurate and combined readings of temperature and relative humidity in onboard interior spaces. Its brass construction gives it high resistance to marine corrosion and a classic nautical finish, ideal for installations in cabins, bridges, or control rooms. The large analog dial (95 mm) makes easy reading even in low visibility conditions. It is a reliable instrument for environmental monitoring on recreational or professional vessels requiring on-board thermal and humidity control.
