{"product_id":"millers-music-acoustic-digital-thermometer-and-piano-hygrometer","title":"Millers Music Acoustic Digital Thermometer and Piano Hygrometer","description":"\u003cp\u003eAcoustic pianos are precision instruments that demand stable environmental conditions to maintain their structural integrity and sound quality. Wood is hygroscopic—it naturally absorbs and releases moisture in response to humidity changes. Fluctuations cause the soundboard to warp, the action to misalign, and tuning stability to suffer dramatically. Temperature swings compound this problem by affecting wood expansion and contraction, while also destabilising the delicate regulation of hammers, strings, and pedal mechanisms. Excessive humidity promotes rust on metal components, swelling of wooden parts, and mould growth. Low humidity causes wood to shrink, leading to cracks in the soundboard, loose joints, and a thin, brittle tone. Both extremes shorten the lifespan of your instrument and trigger costly repairs.\u003c\/p\u003e\n\u003cp\u003eThe Millers Music Acoustic Digital Thermometer and Piano Hygrometer monitors both conditions in real time, displaying precise temperature and humidity readings with an integrated digital clock and date display. This allows you to identify environmental problems before they damage your piano.\u003c\/p\u003e\n\u003cp\u003eThe dual-sensor design gives you complete climate awareness at a glance. Flexible installation suits any space—mount it on your wall for permanent monitoring or use the integrated kick stand to position it on your piano desk or nearby furniture. Maintaining optimal conditions (18–22°C and 40–50% relative humidity) protects your investment and preserves the rich, responsive tone your piano deserves.\u003c\/p\u003e","brand":"Millers Music","offers":[{"title":"Default Title","offer_id":57085290578295,"sku":"HYGR-01","price":25.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/8823\/4062\/files\/IMG_2157.jpg?v=1778590325","url":"https:\/\/millersmusic.co.uk\/products\/millers-music-acoustic-digital-thermometer-and-piano-hygrometer","provider":"Millers Music","version":"1.0","type":"link"}
