D'Addario GH-HTS humidity & temperature sensor + humidifier

General

An almost indispensable set for those who want to keep their acoustic guitar in good condition and avoid repairs: the D'Addario GH-HTS. The Humidity & Temperature Sensor is a hygrometer cum thermometer that you place in your guitar case with your instrument. The HTS then accurately records the humidity level and temperature in Celsius or Fahrenheit.

The right moisture balance with the GH-HTS

The device features a programmable set point, a clock, calendar and memory function, to display the highest and lowest levels your guitar has been exposed to. Ensure the right moisture balance by using the included D'Addario GH Acoustic Guitar Humidifier. You hang it in the sound hole for 24 hours, sandwiched between the strings. If the sponge then dries up, you moisten it again and repeat the process until it no longer dries up.
