## Key values

- **Manufacturer:** CORNET Microsystems Inc.
- **Model:** ED88TPlus5G2
- **Type:** Multi-field meter
- **Instrument class:** Broadband RF power-density meter
- **Quantities measured:** power density, electric field strength, magnetic flux density, frequency
- **Axes:** single
- **Peak hold:** Yes
- **On-device logging:** Yes
- **Declared accuracy:** Manufacturer-stated error: RF ±3.5 dB, LF magnetic 20%, electric field 25% — Manufacturer figure, not an independent verification.
- **Market status:** Currently sold

## Frequency coverage by mode

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

- **power density** — RF: 100 MHz – 8 GHz
- **magnetic flux density** — LF magnetic: 50 Hz – 10 kHz
- **electric field strength** — LF electric: 50 Hz – 50 kHz
- **frequency** — Frequency counter: 100 MHz – 4.2 GHz

## Display range by mode

- **RF power density** — 0.5 µW/m² – 1.8 W/m² (−60 to +5 dBm)
- **RF field strength** — 14 mV/m – 26.2 V/m
- **LF magnetic, 50 Hz – 10 kHz** — 0.1 – 60 µT (1 – 600 mG)
- **LF magnetic, 50 Hz – 1 kHz** — 0.01 – 1 µT (0.1 – 10 mG)
- **LF electric** — 10 – 1,000 V/m

## Calibration

No calibration certificate is offered in the manual; the meter has a user-settable frequency-band correction factor rather than a traceable calibration.

## Suited to

- A first survey where RF, wiring magnetic fields and electric fields all have to be looked at with one instrument
- Attributing an RF reading to a service, because the frequency counter reports the dominant carrier up to 4.2 GHz
- Unattended recording: 1,000 samples down to 0.001 s intervals, exportable over USB

## What it cannot do

- Not a three-axis instrument in any mode — every reading is orientation dependent
- The frequency counter stops at 4.2 GHz, so a 5 GHz Wi-Fi or 6 GHz reading cannot be identified even though it is measured
- Above 8 GHz is out of specification, and the '10 GHz' figure in the maker's comparison table is a coverage claim rather than a specified measurement range
- The stated LF magnetic and electric tolerances of 20% and 25% are far wider than a metrology-grade gaussmeter, so it will not settle a marginal comparison against a limit
- No accredited calibration, so its numbers do not carry evidential weight in a formal complaint

## 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.
