Seth Burgin from PHOENIX, AZ USA
Close enough for what I do!
After 55 years one of our guitars developed a crack. Fine musical instruments and some master tapes, along with other items should be stored in a controlled environment. This can be an integral part in controlling a humidifier, & thermostat. Newer furnaces, have a humidifier, but you can add a separate humidifier. 45% RH is about optimum! You can both monitor, control and even chart your temp & RH with this, and some other parts! It's pretty accurate too. I even put one in the stickering, racking & drying room for seasoning fine hardwoods.
