Frequently Asked Questions
Q: Does this analog hygrometer require batteries or electricity?
A: No — this is a fully mechanical hygrometer. It uses a precision mechanical movement to detect and display relative humidity with no batteries, cables, or electricity required, making it ideal for enclosed spaces like instrument cases and wine boxes where wiring is impractical.
Q: What is the humidity measurement range of this gauge?
A: The dial covers the full 0%–100% relative humidity (RH) range, giving you accurate readings across a wide variety of indoor and outdoor environments, from very dry storage rooms to humid greenhouses and basements.
Q: Which size should I choose — 37 mm or 27 mm?
A: The 37 mm (approx. 1.46 inch) version is better for wall mounting or open-shelf placement where a larger dial is easier to read at a distance. The 27 mm (approx. 1.06 inch) model is more compact and ideal for guitar cases, cigar boxes, tea tins, and other tight spaces.
Q: Is this hygrometer suitable for outdoor use?
A: Yes. The zinc alloy body is durable enough for covered outdoor areas such as patios, greenhouses, and garages. Avoid prolonged direct exposure to heavy rain or immersion in water.
