TES-1358E Class 1 Real-Time Sound Analyzer

Description

The TES-1358E is a Class 1 real-time sound analyzer manufactured by TES Electrical Electronic Corp. It is designed for high-precision acoustic measurements in professional applications like environmental noise monitoring, industrial noise measurement, and sound effect analysis. The device's primary function is to perform real-time frequency analysis, breaking down complex noise signals into their component parts.

Key Features

• Real-time octave band analysis: The TES-1358E can perform real-time analysis across 1/1-octave and 1/3-octave frequency bands, which is essential for detailed sound spectrum analysis.
• High accuracy: It conforms to the IEC 61672-1 Class 1 standard, indicating high precision and reliability. The accuracy is specified at ±0.7 dB (referenced at 94 dB @1 kHz).
• Wide frequency and dynamic range: The analyzer measures a broad frequency range from 12.5 Hz to 20 kHz, with a dynamic range of 90 dB.
• Advanced measurements: It provides several measurement functions, including Lp (sound pressure level), Leq (equivalent continuous sound level), Lmax (maximum level), and Lmin (minimum level).
• Data storage and transfer: The unit comes with a 4GB micro SD card for data logging and a USB interface to transfer measurement data to a computer.
• Trigger functionality: Measurements can be initiated by an internal or external trigger, and the device has a comparator output to trigger other external devices.
• Clear display: It features a high-contrast, backlit 3.5-inch TFT-LCD color display for easy viewing of data.
• Multiple frequency weightings: For different types of acoustic assessments, the device offers A, C, and Z (flat) frequency weighting options.
• Versatile power supply: The unit can be powered by four C-size batteries or an external DC power supply.
