# AlphaLab AC Milligauss Meter UHS2

> Three-axis true-magnitude AC gaussmeter covering 13 Hz to 75 kHz to 1999.99 mG at 0.01 mG resolution, typically ±3% between 45 Hz and 5 kHz, supplied with a NIST-traceable calibration certificate.

## Key values

- **Manufacturer:** AlphaLab, Inc.
- **Model:** UHS2
- **Type:** Broadband meter
- **Instrument class:** ELF gaussmeter (power-frequency magnetic field)
- **Quantities measured:** magnetic flux density
- **Axes:** triple
- **Peak hold:** No
- **On-device logging:** No
- **Declared accuracy:** Typically ±3%, maximum ±7%, between 45 Hz and 5 kHz — Manufacturer figure, not an independent verification.
- **Market status:** Currently sold

## Frequency coverage by mode

One band per measuring mode, as the manufacturer states it.

- **magnetic flux density** — 13 Hz – 75 kHz (−3 dB), with a 1 kHz – 75 kHz VLF-only setting

## Display range by mode

- **AC magnetic flux density** — up to 1999.99 mG (resolution 0.01 mG)

## Calibration

Supplied with a NIST-traceable calibration certificate; annual recalibration is offered by AlphaLab.

## Suited to

- Quantitative magnetic-field work where the number has to be defensible: three-axis true magnitude, 0.01 mG resolution and traceable calibration
- Separating power-frequency fields from higher-frequency content using the VLF-only setting
- Finding the dominant field direction with the single-axis setting

## What it cannot do

- Magnetic fields only — no electric field, no RF, no body voltage
- No static (DC) magnetic field measurement; this is an AC instrument
- No logging output, so it answers 'how strong now', not 'what happened overnight'
- Response is specified from 13 Hz, so it says nothing about static fields or sub-13 Hz content

## What these figures are

Every number on this page is the manufacturer's own declared specification, reproduced so that models can be compared field by field. Nothing here is an independent test of the instrument, a calibration certificate, or a statement that a reading taken with it can be compared with a regulatory limit — that depends on the detector, the averaging and, where it matters legally, an accredited calibration.
