testo 816-1 - Sound level meter
The testo 816-1 sound level meter offers high-precision measurement and analysis of noise pollution in professional environments. In contrast to less comprehensively equipped basic variants, this solution enables reliable measurement even in complex environments. Particularly in industry, manufacturing and public places, precise noise control must be guaranteed at all times, which is ensured by conformity to IEC 61672-1 Class 2 and ANSI S1.4 Type 2. The [testo 815 - sound level meter], which is also suitable for accurate measurements in health and safety environments, has similarly robust properties.
Performance features and special features
Professional noise measurements can only deliver reliable results if both precise sensors and flexible setting options are available. Here, the device impresses with a wide range of functions and high-quality workmanship:
- Measuring range from 30 to 130 dB for a wide range of applications
- Frequency range between 20 Hz and 8 kHz, so that even low frequencies can be evaluated accurately.
- Accuracy of ±1.4 dB under reference conditions (94 dB/1 kHz).
- Time weighting of Fast (125 ms) and Slow (1 second) for scalable depth of analysis.
- A and C weighting to determine different frequency components.
- Integrated memory for up to 31,000 measured values.
- USB interface with PC software for data transfer and live display for long-term measurements.
With a dynamic range of 100 dB and a 0.5"microphone, the measuring device detects the smallest volume increments just as reliably as large level jumps. The robust yet compact design (272 x 83 x 42 mm) facilitates mobile use and, together with the low weight of 390 g, ensures convenient transportation in everyday working life. Thanks to the illuminated display, the measurement data can be read even in poor lighting conditions.
A particular highlight is the internal data logger, which reliably stores measurement series. This function is particularly useful if noise levels are to be determined over longer periods of time in order to carry out a comprehensive immission assessment. The software also makes it possible to track measurement data live on the screen of a connected computer, which is very helpful for maintenance work in noisy production halls or for analysis at event venues, for example.
Typical areas of application
When measuring noise in occupational safety, limit values must be consistently monitored so that personnel are protected from harmful noise exposure. The device is used in factories or production halls as well as in road or rail transport to implement measures such as noise protection or organizational adjustments in good time. Permanent monitoring of decibel levels is also very important in the event industry, for example at music festivals or sporting events, in order to protect residents from noise disturbance and to comply with legal regulations. It is also suitable for long-term measurements in office environments, where pleasant acoustics are essential for undisturbed working.
Typical substances or materials for which it makes sense to carry out sound level evaluations include metalworking machines in production facilities, compressed air-driven tools in workshops and ventilation systems in office buildings. Periodic checks can be used to assess whether maintenance-related wear and tear or other factors are leading to increased noise levels and unnecessary noise pollution instead of timely repairs.
FAQs
How is calibration carried out
?
The device can be calibrated on site using an optional sound calibrator. A screwdriver included in the scope of delivery allows for quick fine adjustment so that the measuring device always delivers accurate measured values.
Is long-term data acquisition possible?
Yes, thanks to the integrated memory for 31,000 measured values, even longer phases can be recorded without gaps. The PC software supplied also offers the option of recording and evaluating live data while the device is connected to a PC.
Which frequency weightings are available
The measurements can be analyzed according to both A and C characteristics. This allows an analysis according to human hearing perception as well as a consideration of the low-frequency components.
Is the device suitable for all climatic conditions?
It is designed for operating temperatures between 0 and +40 °C. For storage, the storage temperature of -10 to +60 °C should be observed to ensure the long-term functionality of the device.
Can the display also be read in poor lighting conditions?
Thanks to the backlight, reading the measured values is easy and error-free even in darker environments.
Conclusion
The sound level meter offers a comprehensive solution for industry, trade, occupational health and safety and anyone who needs to carry out professional sound measurements. With its wide frequency range, high accuracy and customizable measurement modes, it enables both selective and long-term measurements. The integrated data storage and software support round off the overall package, providing users with a versatile and reliable platform for noise analysis.
