Length: 48 mm
Inner threading for preamp.: 11.70-60 UNS-2
Outer threading for mic.: 11.70-60 UNS-2
Material: stainless steel


The dehumidifier contains silica gel and removes humidity from the air in the microphone. When being saturated silica gel changes colour from orange/amber to white. The humidity removing properties are regained by drying it out. To to this, heat it for some hours at 100 degrees Celcius (or longer at lower temperature).
