Important Feature #1 – Triple Axis: The Alpha UHS2 is an accurate triple-axis gaussmeter. Most lower-cost meters are only the single-axis type. With a single-axis meter, you must manually rotate the meter around to find the highest field direction. If you do not orient the meter correctly, you will under-measure the field strength. In fact, to get a truly accurate measurement, you must position a single-axis meter in three orthogonal directions and then perform a math calculation to get the total field strength. A triple-axis meter simplifies all this for you. It has three sensor coils built in that automatically take the three measurements and do the math for you. Therefore, most people will get much more accurate readings with a triple-axis meter. In contrast, with a single-axis meter, most users will underestimate the true field strength.
Important Feature #2 – Detects ELF and VLF: The Alpha UHS2 detects a wide range of frequencies — including both the ELF and VLF frequency ranges. Most gaussmeters detect only in the ELF frequency range. ELF (extremely low frequency) includes the common 60 Hz frequency fields from power lines, wiring, refrigerators, transformers, lights, appliances — everything that runs on regular electrical power. VLF (very low frequency) includes higher frequencies of around 10,000 Hz and more, that often come from computers, televisions, electronics, switching power supplies, fluorescent lights, compact fluorescent bulbs, LED bulbs, etc.
Buying a new home or renting a new apartment? This is the meter we recommend for testing the magnetic fields from power lines and electrical wiring before you buy or rent a new home.
This is the lowest cost gaussmeter available with these 3 important features: (1) triple axis antenna, (2) detects both ELF and VLF magnetic fields, and (3) accurate enough to trust and use its measurements.
Also sometimes called “AC Milligauss Meter”, “Alpha UHS”, “Model UHS”, “Alpha Model UHS2”, or “Switchable Single Access and 3-Axis Gaussmeter”. It is manufactured by Alpha Lab, in the USA.
