GTECH - DIGITAL SOUND LEVEL METER (SL-102) +FREE CALIBRATION CERTIFICATE

The G‑Tech SL‑102 is a portable digital sound level meter used to measure sound pressure levels (noise) in various environments. It’s suitable for industrial, environmental, workplace, and general acoustic monitoring — helping determine noise levels for safety, compliance, and comfort.

🔍 Key Features

• 30 dB to 130 dB range covers quiet to very loud environments.
• Can display results in A‑weighting (dBA) and C‑weighting (dBC) (A‑weighting mimics human ear sensitivity; C‑weighting is flatter).
• Accuracy: ±1.5 dB (under standard conditions).
• Resolution: 0.1 dB for precise readings.
• Frequency Response: ~31.5 Hz to ~8 kHz, capturing most audible sounds.
• 4‑digit digital display shows readings clearly.
• Sample rate: Typically ~2 readings per second.
• May include an analog bar graph for visual monitoring.
• Fast / Slow time weighting: Adjusts how quickly the meter responds to changes in noise level.
• Often supports Max/Min or data hold features (depending on version).
• Uses a 1/2‑inch electret condenser microphone for reliable sound capture.
