PCE Instruments SLT-TRM Class II (Type 2) Sound Level Transmitter 4 to 20 mA

Model # SLT-TRM

PCE-SLT-TRM 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-TRM 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.
IP 54 ingress protection rating on transmitter offers limited protection against dust ingress (no harmful deposit) and protection against splashed water from any direction.
