Mondi Mini Greenhouse Thermo-Hygrometer | Min/Max, Dome Mount

What the Greenhouse Thermo-Hygrometer Reads Inside a Dome Opening a dome to check it changes what you are checking. Lift the lid and humidity drops before the meter settles. This unit mounts on the dome wall and reads from inside, so the number you see is the number the cuttings live in. It holds min and max history beside the live reading, which shows you the overnight swing rather than one moment. Picking a Hygrometer for Greenhouse Propagation Work Range is what rules most meters out at the propagation bench. This one reads 25% to 98% RH, which covers a domed tray at the wet end where a household meter tops out near 90%. Temperature runs -9.9 to 50 C, roughly 14 to 122 F. It switches between Celsius and Fahrenheit, so it fits whichever scale your logs already use. Power is a single L1154H cell, included, and the body is 130 mm wide by 30 mm tall at 25.5 g. Mondi builds it on Japanese sensor components. Key Features Reads without opening the dome: Lifting the lid drops humidity before a meter settles. This one stays inside. 25% to 98% RH: Covers a domed tray at the wet end, where a household meter stops near 90%. Min and max memory: Shows the overnight swing, not only the number at the moment you walk past. -9.9 to 50 C: About 14 to 122 F, with Celsius and Fahrenheit switchable on the unit. One L1154H cell, included: 25.5 g and 130 mm wide, so it hangs on the dome wall rather than a stand. Japanese sensor components: Mondi builds the movement around them, in a housing that takes dome humidity.
