Compare Bedrock Elite acoustic measurement instruments across all key parameters: IEC accuracy class, STIPA capability, Full STI, octave band analysis, reverberation time, statistical analysis, data logging, FFT, GPS, and price. Every instrument in this comparison ships fully unlocked with all advertised modules included — no hidden costs, no firmware gates, no post-purchase unlock fees.
Understanding the differences between the i10, i9, and i5: the i10 and i9 are IEC 61672-1 Class 1 instruments; the i5 is Class 2. All three include STIPA, full octave analysis (1/1, 1/3, 1/6, 1/12), and 32768-line FFT. The i10 adds Full STI (in under 60 seconds), B-weighting, a built-in signal generator (pink/white/sine/STI), WiFi and Bluetooth, a TRRS output, and 32 GB storage. The SM series (SM90, SM50, SM30) covers environmental and occupational noise applications with and without STIPA.
