Habotest Sound Level Meter

Description

HABOTEST HT602A / HT602B Sound Level Meter is a handheld digital sound pressure meter designed for accurate noise measurement and environmental monitoring. Both models feature a clear digital display, analog bar indicator, and support FAST and SLOW time weighting for flexible measurement in different environments.

The HT602 series measures sound pressure levels across a wide range and supports frequency weighting for reliable readings. In addition to sound level measurement, the device can measure ambient temperature, humidity, wet bulb temperature, and dew point temperature, making it suitable for workplace monitoring, environmental checks, and general sound analysis.

Both models include practical functions such as data hold, maximum and minimum value tracking, backlight, automatic power off, and low battery indication. Power is supplied by three AAA batteries, and the compact size allows for easy handheld operation.
