Introducing the TES-660 Noise Dosimeter
TES-660 Noise Dosimeter; in many industrial environments, the main issue is not just the "loudness of sound," but the duration of the worker's exposure to noise is even more important. Many hearing damages occur when a person is continuously exposed to medium to high noise levels throughout the work shift.
In such conditions, using conventional devices like sound level meters is not enough; because these devices only display instantaneous sound levels. Therefore, a more precise tool called a Noise Dosimeter is used.
TES-660 is a professional wearable noise dosimeter from the Taiwanese brand TES that is mounted on the user's body and measures and records the actual sound exposure over time. This device is designed according to international standards ANSI S1.25 and IEC 61252 and is fully suitable for HSE and occupational health applications.
Wearable, Lightweight, and Cable-Free Design of TES-660
One of the most important features of the TES-660 is its small and lightweight design.
This device:
Operates without a separate microphone cable
Is mounted directly on clothing or the body
Has a very low weight (about 77 grams)
Is suitable for use during long work shifts
This design ensures that the recorded data is completely realistic because the user works naturally without movement restrictions.
Noise Dose Measurement
Unlike conventional sound level meters, TES-660 does not just show the instantaneous dB value but:
✔ Calculates cumulative sound exposure
✔ Records Noise Dose over time
✔ Enables assessment of hearing damage risk
This feature is vital for occupational safety evaluation because hearing loss is usually gradual and time-dependent, not instantaneous.
Measurement Range 70 to 140 Decibels of TES Noise Dosimeter
TES-660 has a wide dynamic range:
70 dB to 140 dB
Also, peak range up to:
103 dB to 143 dB
This range makes the device suitable for both typical industrial environments and very noisy settings.
Exchange Rates
This device supports several noise dose calculation models:
3 dB
4 dB
5 dB
6 dB
This capability allows TES-660 to comply with different safety and occupational health standards in various countries.
Complete Acoustic Parameters of Noise Dosimeter TES-660
TES-660 does not just provide a simple number but records the following professional parameters:
Leq (Equivalent Continuous Sound Level)
Lavg (Average Sound Level)
LCpeak (C-weighted Peak)
LZpeak (Linear Peak)
These data are used for specialized environmental noise analysis and HSE reporting.
Frequency Filters A, C, and Z
This device supports three standard weighting types:
A-weighting (according to human hearing)
C-weighting (for stronger sounds)
Z-weighting (linear, unfiltered)
This makes noise analysis more accurate and reliable.
Internal Memory and Data Logging
TES-660 can store up to about 30 measurements.
Also provides:
Data recording at different time intervals
Viewing and downloading information
Reviewing different work shifts
Timer and Automatic Measurement
This device supports an advanced timer system:
Automatic start and stop of measurement
Scheduling up to 99 timers
Capability to record data during long shifts
This feature is very useful for industrial and HSE projects.
Audio Warning Alarm
TES-660 has an LED alert that:
Warns the user when noise exceeds the permissible limit
Indicates hazardous conditions
This feature is very important for preventing hearing damage.
Rechargeable Battery of TES-660 Noise Dosimeter
The device has a 3.7V lithium polymer battery.
Features:
