Description

The FNIRSI FDM01 noise level meter is a versatile and compact measuring device for precise monitoring of noise levels in the range of 30 to 130 dB. With a sensitive 6-mm condenser microphone and a well-readable 2.3-inch VA color display, the device not only provides accurate measurements but also simultaneous display of temperature and humidity. The fast response time and the selection between different measurement modes (FAST/SLOW) allow for flexible application in various environments, whether in the office, on construction sites, or in public areas. A light alarm signals when the set sound level is exceeded, while the HOLD function retains current values on the display. Thanks to the rechargeable lithium battery and the robust housing, the FDM01 is ideal for use in demanding conditions.
