Testo Sound Level Meter 816-1 can, at the touch of a button, be switched from Slow (1 sec) to Fast (125 ms). It is also possible, again at the touch of a button, to switch between the frequency weighting characteristic curves A and C and vice versa. Characteristic curve A corresponds to the sound pressure sensitivity of the human ear, while characteristic curve C can evaluate low-frequency components of a noise. The 816-1 integrated data store allows storage of more than 30,000 measurement values that can be administered using the software included. Additionally, the supplied software allows online measurements over a longer period to be carried out. Applications of the 816-1 include sound level measurements at workplaces, in industrial and production halls, and in public places. The instrument is powered by AA (x4) batteries.

Easily record sound level measurements with this data logger from Testo. For enhanced versatility, it features two selectable frequency weighting curves, letting you check both the audible and low-frequency aspects of a sound simultaneously. You can adjust the recorder's measurement time between 125ms and 1s to monitor persistent and intermittent sounds. Thanks to its accuracy of ±1.4dB (decibels) and a resolution of 0.1dB, this data logger gives you precise sound level readings.

• Measures sound output levels between 30 and 130dB for use in quiet and loud environments
• Memory of up to 31,000 readings for ample storage space
• Built-in wind protection minimises interference from sudden winds for more accurate measurements
• Robust battery life of 40 hours for long-lasting portable use

• Office spaces
• Production lines
• Construction industry

The data logger includes USB connectivity, making it simple to transfer data to a personal computer. You can use the included software to import and analyse readings for enhanced monitoring capabilities.
