Quest® Sound Examiner SE-400 Sound Level Meter

The SE-400, part of the Quest® Sound Examiner series from TSI Incorporated, is designed to measure air sound pressure levels and is used in a variety of applications such as occupational and environmental noise evaluation, sound quality control, acoustic research, and noise standard compliance.

SE-400 Models:

• Class/Type 1 Models: Offer the highest accuracy and are ideal for applications requiring the utmost precision.
• Class/Type 2 Models: More cost-effective and suitable for most applications.

Key Features of the SE-400:

• Streamlined Shape: Minimizes disturbance of sound fields being measured, ensuring accurate readings.
• Onboard Data Logging: Captures maximum, minimum, and peak values at intervals down to 1 second for thorough analysis.
• Wide Frequency Range: Measures from 31.5 Hz to 12.5 kHz.
• Four Frequency Weightings: A, C, Z, and N.
• Large, Easy-to-Read Display: Shows current sound pressure level, equivalent sound pressure level (L_eq), maximum sound pressure level (L_max), and minimum sound pressure level (L_min).
• Rechargeable Battery: Provides up to 18 hours of continuous operation.
• SoundWare Software: Included for data transfer to a computer for further analysis.

SE-400 IS Models:

The SE-400 IS models are intrinsically safe and certified for use in hazardous environments, including those with an explosion risk.
