DTM4137 Audio Distortion Meter
A bench instrument for measuring distortion, noise, and signal quality in audio and analog circuits. Auto-ranging and an LED display make readings fast, and it resolves distortion as low as 0.005%.
Use it for: audio amplifier and equipment testing, production QC, repair benches, R&D labs, and teaching labs.
You can:
Measure total harmonic distortion from 100% down to 0.005%
Measure S/N ratio (0 to 99.99 dB) and SINAD (0 to 80 dB)
Measure AC voltage (RMS) from 300 µV to 300 V, and frequency
Test unbalanced signals from 10 Hz to 150 kHz, or balanced signals from 10 Hz to 100 kHz
Handle input levels from 50 mV to 300 V
Read results with auto-ranging, with display resolution down to 0.0001% and 0.01 dB
Key specs:
Level accuracy: ±0.5 dB (20 Hz to 20 kHz), ±1 dB (10 Hz to 150 kHz)
Residual distortion and noise (≥1 Vrms): ≤0.0055% (20 Hz to 20 kHz), rising to ≤0.016% at 100 to 150 kHz
Input impedance: 100 kΩ // 100 pF
Specs: 110-127 V / 220-240 V (50/60 Hz), 350 × 120 × 340 mm, 5 kg.
The DTM4137 Series Distortion Meter provides precise measurement of distortion, signal-to-noise ratio (S/N), SINAD, voltage, and frequency across a wide range. With auto-ranging, LED display, and distortion measurement capability down to 0.005%, it ensures accurate analysis for audio and electronic testing. Supporting frequency ranges up to 150kHz and advanced statistical accuracy, the DTM4137 is ideal for laboratories, R&D, and production environments requiring reliable distortion and noise evaluation.
