TES 1350A Sound Level Meter

TES 1350A Sound Level Meter

This unit was designed according to the IEC651, ANS1 S1, 4 for Sound Level Meters.
The Sound Level Meter has been designed to meet the measurement requirements for Industrial safety offices and sound quality control in various environments. Ranges for 35dB to 130dB at frequencies between 31.5Hz and 8KHz. Display with 0.1dB steps on a 4-digits LCD. With two weighting, A and C. Both AC and DC signals output is available from a single standard 3.5mm coaxial socket suitable for a frequency analyzer, level recorder, FFT analyzer, graphic recorder; etc. The unit measures 240 (l) x 68 (w) x 25 (h) mm and weighs approximately 210 g .
