NL-28 is a class 2 sound level meter that complies with the Measurement Act, JIS, and IEC. The measurable frequency range is 20 Hz to 8 kHz.

It consists of a main unit including a 1/2-inch microphone and a preamplifier. The main unit is equipped with operation keys and an organic EL display.

There is a function to simultaneously measure the time-weighted sound level, equivalent continuous sound level, sound exposure level, maximum time-weighted sound level, and peak sound level (C-weighting only), and the results are recorded on the main unit.

The device has a wide linearity range of up to 107 dB, and does not require range switching when measuring.

Measurement data can be transferred by connecting the USB terminal to a computer.
