Photo (LA-1200 series Sound Level Meters)

The LA-1200 series (consisting of four models) achieves a wide linearity range of 85 dB and operates no less than 40 hours continuously with two type AA batteries.
The series includes models with memory, comparator and external control functions, which enables to capture sudden noise and synchronous operation of several meters.

LA-1200 is designed for operational easiness to be realized at the measurement site.

Features

  • Wide 85-dB linearity range

  • Long battery life, realizing approx. 40-hours continuous operation

  • Setup resume function for quick startup of measurement, with measurement condition storage

  • Key protection function to prevent erroneous or accidental operation

  • Comparator output and external control setting capability

  • Time scheduled operation for environmental measurements (on LA-1250)
