ACO Waterproof Sound Level Meter, Model 6226NW

ACO Waterproof Sound Level Meter, Model 6226NW

It can be used at the site to be expected as high-humidity environment with rain or sheet of spray.

TYPE 6226NW is a "waterproof sound level meter" with included extension cable, realized by particular kind of waterproof technology newly developed.

It guarantees trouble-free measurement even under rainy condition.

Due to the function of special filter which lets air and sound through preventing water from coming in, it allows to continue the measurement despite of drops of water on the top of the microphones after they are dried up.

The diaphragm or preamplifier would never be waterlogged or rust out.
