Unlike the spiral hygrometer, which indicates correctly within a certain range of the humidity scale, the synthetic hair hygrometer can be adjusted in such a way that it indicates reliably over the total humidity scale. This small synthetic hair hygrometer is, for that very reason, a high precision instrument.
This brass instrument is less than 3 inches in diameter making it ideal for permanent wall mounting in key locations such as in a greenhouse.
