Sound level monitors in comparison

4-in-1 Decibel Meter This decibel meter uses excellent acoustic sensors and precise measurement technology to accurately detect noise levels in the range of 30-130dBA. It also supports temperature and humidity detection, with adjustable temperature units in both Fahrenheit and Celsius. It can also be used as a clock with accurate time display.

High precision the sound level meter uses an intelligent air semiconductor sensor to measure the decibel temperature and humidity values, which is more sensitive, accurate and stable. The measuring range is 30 130dB, the accuracy is 5%dB, and the frequency range is 50Hz 8.5KHz, resolution 0.1dB; humidity range 20 85%, accuracy 5%; temperature range -10 50 , accuracy 5%

USB Powered Connecting computer with USB cable, you can down-load records, collect samples and print chart and date,etc.

Sensitive Sensor 0.5s response time, no contact. Can measure noise level under any circumstances, quickly display accurate measurement result.
