Introduction to TES-1352S Sound Level Meter TES-1352S Sound Level Meter : Today, noise pollution has become one of the most significant challenges in industrial and urban environments. Exposure to excessive noise can lead to reduced concentration, fatigue, decreased productivity, and even permanent hearing damage. Therefore, accurate measurement of sound intensity and continuous monitoring is of special importance in many industries and occupational health projects. TES-1352S Sound Level Meter is an advanced device from TES Taiwan designed to measure, record, and analyze various sound parameters. This device belongs to the category of integrating sound level meters and, besides displaying real-time sound intensity, it also enables calculation of average sound energy and long-term data storage. Unlike simple sound level meters that only show instantaneous decibel values, the TES-1352S can record various analytical parameters, making it widely used in noise pollution studies and HSE projects. Features of TES-1352S Decibel Meter This device offers a set of practical and professional features to users: Measurement of SPL, Leq, and SEL Calculation of statistical Ln values IEC 61672-1 Class 2 standard Internal data logger Data storage on memory card USB connection to computer Frequency weighting A and C Time response Fast, Slow, and Impulse Large LCD display with bar graph AC and DC output These features make the TES-1352S a reliable tool for safety engineers and environmental experts. Measuring Sound Intensity with TES 1352S Sound Level Meter The primary function of this device is to measure the Sound Pressure Level (SPL). Measurement range: 30 to 130 decibels which covers a wide range of environmental and industrial applications. This range allows sound measurement in various environments, including: Office environments Factories Power plants Manufacturing workshops Educational centers Construction projects Urban traffic Therefore, the TES-1352S is suitable for most noise control applications. Calculating Equivalent Continuous Sound Level (Leq) One of the important features of this device is measuring Leq or equivalent continuous sound level. Leq represents the average sound energy over a specified time period and is highly important in occupational health standards. This parameter helps evaluate the actual exposure of individuals to sound, making its use essential in HSE projects and environmental noise monitoring. Calculating Sound Exposure Level (SEL) In addition to Leq, the TES-1352S can calculate SEL. SEL indicates the cumulative sound energy during a specific event and is widely used for occupational exposure assessment and analysis of variable sound sources. This capability makes the device suitable for evaluating acoustic conditions in industrial and urban environments. Statistical Noise Analysis with Ln Parameters One of the differences between the TES-1352S and many ordinary decibel meters is the ability to calculate statistical sound values. This device can calculate the following: L5 L10 L50 L90 L95 For example: L10 is commonly used for traffic noise analysis. L90 is used to determine background environmental noise. L50 shows the median of sound variations. These parameters make the TES-1352S very useful for environmental studies and acoustic research. Frequency Weighting in TES-1352S Decibel Meter This device supports two standard frequency filters: A Weighting This filter simulates human ear sensitivity and is used in most HSE measurements. C Weighting This filter is suitable for measuring industrial noises and low frequencies. Having both filters allows the device to perform well in various applications. Time Response Modes TES-1352S offers three time response options: Fast For rapidly changing sounds. Slow For environments with gradual sound changes. Impulse For impact and sudden sounds. These options enable users to select the best measurement method according to the project type. Data Storage and TES Sound Level Meter Data Logger In many projects, it is necessary to record sound data for extended periods. TES-1352S is equipped with a data logger system and allows data storage on a memory card. Thus, users can: Record data. Prepare long-term reports. Analyze noise changes over time. This feature is especially important in environmental monitoring projects and noise pollution studies. Computer Connection and Data Analysis This device is equipped with a USB interface. Using dedicated software, users can: Download data. View sound variation charts. Prepare specialized reports. Save information for further analysis. This capability makes TES-1352S a professional tool for engineering projects. Applications of TES-1352S Sound Level Meter This device is used in various fields: Industries and factories HSE projects Urban noise monitoring Oil and gas industries Acoustic research Occupational noise exposure assessment Environmental studies Airports Hospitals Construction projects Advantages of Using TES1352S Decibel Meter ✔ IEC 61672-1 Class 2 standard ✔ Measurement of SPL, Leq, and SEL ✔ Statistical noise analysis ✔ Internal data logger ✔ USB interface ✔ AC and DC output ✔ A and C weighting ✔ Fast, Slow, and Impulse response ✔ Suitable for industrial and environmental projects ✔ Made in Taiwan Why is TES-1352S Sound Level Meter a Good Choice?
