Xtester-TW409A Class 2,1/1OCT,Sound Level Meter,SONÔMETRO,Decibelímetro Digital

INTRODUCTION

Xtester-BSWA308-A,BSWA308-B,BSWA309-A,BSWA309-B are new generation octave sound level meter,they update the dual core (DSP+ARM) architecture to single chip ARM with float point unit, and update all fix--point calculation to floatpoint calculation which significantlignificantlyy improves the accuracy and and stability. Re-design analog front end circuit also lower the noise floor and linear range of product.

Xtester-BSWA308-A,BSWA308-B are Class 1 , and BSWA309-A,BSWA309-B are Class 2. Both instruments have ccertificated by the China CPA (Certification of of Pattern Approval)  and CMC (China Metrology Certification)
