Noise Meter / Sound Meter PCE-SLT

PCE-SLT is a class II (type 2) sound level, sound pressure level (SPL), decibel (dB) or noise meter with audible or visual alarm output capability. PCE-SLT is used for long-term, continuous monitoring of occupational noise exposure limits in industrial environments such as foundries, factories and manufacturing production floors. The measuring device consists of a wall-mountable acoustic sensor on a 1.5 m / 4.92′ long cable and a transmitter.

***Includes digital indicator with IP 65 rating***
– Measuring range: 30 … 130 dB in 3 ranges
– Resolution: 0.1 dB
– Accuracy: ± 1.5 dB
– IP 54 ingress protection rating on transmitter offers limited protection against dust ingress (no harmful deposit) and protection against splashed water from any direction
– IP 65 ingress protection rating on digital indicator offers total protection against dust ingress and protection against low-pressure water jets from any direction. Limited ingress permitted.
