Users can employ the wall, desk or tripod mount with the optional 5m (15ft) microphone extension cable for remote monitoring. For even more flexibility, the high or low limit (30 to 130dB) with output to drive external relay module is user adjustable. Even more, the SL130W meets ANSI Type 2 and EN 60651 accuracy specs - compliant to OSHA and complies supplied with a 100-240V AC 50/60Hz adapter and microphone wind cover.
