Noise dosimeter NP-DLX

Noise dosimeter NoisePro with integrated data logging / authorized according to ATEX, EX, UL, cUL, MSHA, SIMTARS

The NoisePro NP-DLX noise dosimeter combines the functions of a sound level meter and integrated data logger in a single device. An optional hanging microphone converts the noise dosimeter into a sound level meter. Optionally, you can request the NP-DLX with the hanging microphone at the same price instead of the standard microphone. The serial interface allows a direct connection to the PC. The values are displayed and recorded, and can be retrieved later as a histogram and printed as statistical analysis, all through the software. You can adjust all parameters on the device itself or through the software. Additionally, the noise dosimeter has ATEX certification and can therefore be used in EX risk environments. The noise dosimeter is shipped with a factory calibration certificate at no additional cost. You can perform subsequent calibrations whether you have the certificate or not.
