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)

LA-1210 Basic type sound level meter	LA-1220 Sound level meter with communications function
Instantaneous level of (L_A) and (L_P) Stationary noise measurement	RS-232C I/F added to LA-1210 Comparator output (optional)

LA-1240 Integrating sound level meter with memory function	LA-1250 Integrating sound level meter for environmental measurements
Equivalent continuous SPL (L_ep) and percentile SPL(L_x) Measurement data stored into built-in memory (300 addresses) Comparator output and external control (optional) Non-stationary noise measurement	Time scheduled measurements Back erase function to remove measurement data up to 10 seconds from the point Built-in memory (Manual: 300 addresses, Block: 14400 addresses) Sudden noise can be recorded using a combination of comparator function and a data recorder. (optional) External control (optional)
