Noise Dosimeter
SV 104
-
The SV 104 is our latest and smallest ever noise dosimeter. It has incredible functionality, taking full noise dosimeter capabilities into a compact style instrument that beats anything else on the market hands down!Any instrument is only as strong as its weakest point and on a noise dosimeter that's normally the microphone. On the SV 104 we've removed that 'Achilles heel' by using a revolutionary and virtually indestructible MEMS microphone.

Noise Location Package
Type HFDF
-
National RF’s Type HFDF high frequency location system is a proven noise hunting and location directional antenna system that allows you, in many cases, to walk right up to the source of High Frequency (HF) noise! Used by several power companies around the United States, professional noise hunters, and other communications specialists, the HFDF has located noise sources that emanated from pole power transformers, arcing electric fences, CATV in-line amplifiers, plasma TV screens, and even Marijuana grower’s heating lamps! The system incorporates several plug-in, tunable magnetic loop sensors of a proprietary National RF design, that cover the frequency range between 1.8 MHz and 55 MHz. The unit is packaged in a hand-held, lightweight metallic enclosure, with a pistol grip and a magnetic compass mounted on top. The compass is used to get magnetic bearings to the noise source, which may be plotted on a map to triangulate, and ultimately pin-point, the location of the noise source. In certain cases, our customers tell us that they have been able to walk right up to the interfering noise source and correct the situation on the spot!
