TECPEL Sound Level Meter - DSL-332

Self-Calibration, 4 Digit LCD display, Low Battery Indication


For the quantification of nearly any noise, investigations on noise pollution frequently use the Tecpel DSL-332 sound level meter. For industrial, environmental, and aircraft noise, it is very suitable and accurate. The meter features a max hold function, fast and slow dynamic characteristic models, a level range of 35–130dB, resolution of 0.1dB, accuracy of 1.5dB, A and C frequency weightings, AC/DC signal output, low battery indication, reset function, and self–calibration at 94dB. The meter complies with ANSI S1.4:1983 Type 2 and IEC61672-1:2013 Class 2 standards. It has a frequency range of 31.5Hz to 8KHz and a level range of LO (Low): 35-95dB and HI (High): 65-130dB with a resolution of 0.1dB.
The sound level meter has a dynamic range of 55 dB, frequency weighting of A & C, and an accuracy of +/-1.5 dB (ref 94 dB @ 1KHz). With an electret condenser microphone, it also has slow and fast time weighting, a maximum hold decay of 1dB/3min, and electrical calibration using a 1KHz sine wave at 94dB internal oscillator. The meter features auxiliary outputs for DC conditioned (10mV/dB nominally impedance:100W) and AC conditioned (0.55Vrms equivalent to each range step impedance:600W).

This sound level meter provides:

  • 4 Digit LCD display.
  • Max hold function.
  • Fast & slow dynamic characteristic models.
  • Level Range from 35 ~ 130dB
  • Resolution 0.1dB, Accuracy ±1.5dB.
  • A & C Frequency Weightings.
  • AC/DC Signal output.
  • Low Battery Indication
  • Reset Function.
  • Self-Calibration 94dB
  • One 9V battery Power supply
  • Dimensions: 240 (L) x 68 (W) x 25 (H) mm
