TES-1358E Octave real-time audio analyzer

Product Introduction

The TES-1385A Octave Band Analyzer features real-time 1/1 and 1/3 octave band analysis capabilities, providing users with the spectrum distribution of sound, aiding in the quick identification of sound sources and understanding of issues. With the use of a TFT-LCD color display, it offers clear visual representation, making it easier for users to identify measurement information, whether dealing with low-frequency sounds or high levels of noise. Equipped with built-in memory card and USB transmission interface, users can transfer measurement data to a computer, providing an ideal solution for noise analysis, thereby enhancing work efficiency and accuracy. The TES-1358C and TES-1358E are 1/1 and 1/3 octave real-time sound level analyzers from TES Electrical Electronic Corp. The key differences between them are as follows: Applicable Standards: TES-1358C: Complies with IEC 61672-1: 2013 Class 2 standards. TES-1358E: Complies with IEC 61672-1: 2002 Class 1 standards, offering higher precision. Frequency Range: TES-1358C: 25Hz to 10kHz. TES-1358E: 12.5Hz to 20kHz, covering a broader frequency range. Accuracy: TES-1358C: ±1.0dB (at reference sound pressure 94dB @1kHz). TES-1358E: ±0.7dB (at reference sound pressure 94dB @1kHz), providing more precise measurements. 1/1 Octave Band Center Frequencies: TES-1358C: 9 bands with center frequencies at 31.5Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, and 8kHz. TES-1358E: 11 bands with additional frequencies at 16Hz and 16kHz, making the center frequencies 16Hz, 31.5Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz. 1/3 Octave Band Center Frequencies: TES-1358C: 27 bands ranging from 25Hz to 10kHz. TES-1358E: 33 bands ranging from 12.5Hz to 20kHz, with more bands and a wider frequency range. Accessories: TES-1358C: Includes a manual, 4 alkaline batteries, carrying case, software CD, USB cable, micro SD card, windscreen, 3.5mm headphone jack, and an AC/DC power adapter. TES-1358E: Includes the same accessories but with a 4GB micro SD card and may optionally include a microphone extension cable. Overall, the TES-1358E outperforms the TES-1358C in precision, frequency range, and the number of analysis bands, making it suitable for applications requiring higher measurement accuracy and a broader frequency range.
