| SECTION 5 - PRODUCT INFORMATION | ||
| HYGROMETERS | ||
| Hygrometers give a reading (in %) of the humidity and come in various types. DIAL — A simple spring-dial hygrometer can be purchased for just a few pounds. They are oniy accurate to around 5% but this gives a good indication of the humidity level. DIGITAL — Although more expensive, digital hygrometers are very accurate and usually have minimum/ maximum settings. PSYCHROMETER — Psychrometers use wet and dry bulbs to measure the humidity. They are accurate but expensive and are only really recommended for commercial growers etc. | ||
