CEMPROTEC 32 PLC Electrosmog Detector | Ultra-Sensitive Broadband PLC Measurement from 1,6 MHz to 68 MHz

CEMPROTEC 32 PLC | Powerline, Low-Frequency and Magnetic Field Detector in One Combo Meter

Want to know fast whether alternating electric fields reach your bed, whether a transformer or charger gives off a magnetic field, or whether your powerline adapters really switch off at night? The CEMPROTEC 32 PLC electrosmog detector gives you a quick, ballpark answer. It picks up electric fields up to 90 V/m and magnetic fields up to 3.000 nT between 10 Hz and 5 kHz, plus broadband PLC from 1,6 to 68 MHz. All three at the same time.

CEMPROTEC 32 PLC: Low-Frequency and Powerline Detection in One Device

French manufacturer EPE Conseil developed the CEMPROTEC 32 as the successor to the ESI 22. Each field type has its own antenna and its own row of 7 LEDs, running from green through yellow to red. One glance tells you which type of field is present and roughly how strong it is. If nothing is detected, only the first green LED lights up.

Broadband Powerline / PLC (1,6 – 68 MHz)

Powerline communication (PLC) sends internet through your home’s electrical wiring. Think dLAN or powerline adapters used instead of WiFi. The signal then runs along the cables throughout the house. With the CEMPROTEC 32, you can quickly check whether PLC is active and whether your adapters are really unplugged or switched off at night.

Alternating Electric Field (10 Hz – 5 kHz, 0 – 90 V/m)

Electric fields build up around cables, sockets, switches, power supplies, computers and bedside lamps, even when nothing is switched on. The CEMPROTEC 32 shows you whether a field is present at your bed, desk or sofa.

Alternating Magnetic Field (10 Hz – 5 kHz, 0 – 3.000 nT)

Magnetic fields appear whenever current flows, for example around transformers, phone chargers, fuse boxes or high-voltage power lines. The detector senses in three dimensions, so you don’t need to line it up precisely.

Two Modes: Standard and Full PLC

Standard Mode

Switch it on and the detector shows all three field types side by side, each on its own row. It refreshes every two seconds, and the PLC readings in this mode are averaged values.

Full PLC Mode

A short press on the PLC ONLY button switches to Full PLC mode. All 21 LEDs now show PLC alone, with finer steps starting at 2 µW/m². You get real-time peak values, and the highest reading stays lit for two seconds. There’s also an audio analysis: the tone follows the modulated frequency. A long press on the same button turns the sound on or off.

Who Is the CEMPROTEC 32 For (and Who Is It Not For)?

A good fit if you want to

• check whether powerline signals and frequencies are present, or really off at night
• find out as an electrosensitive person whether powerline signals are running on the wiring in your home or from the neighborhood
• run a quick, approximate check at home or in the office
• get a first impression of your surroundings, for example before buying or renting a home
• take it on the road, for example to a hotel room

Not a good fit if you need

• precise measurements of electric and magnetic fields, or targeted searches for individual sources
• expert reports or comparisons with limit and guideline values
• WiFi, DECT, Bluetooth, cellular or 5G readings. For those, you need an RF meter

What this means for electrosensitive people
For electric and magnetic fields, the CEMPROTEC 32 gives you no digital readout, only LED steps. The jumps between steps can be big. For magnetic fields, it goes from 470 to 800 nT. If you react to weak fields, add a meter with a digital display like the SAFE AND SOUND EM3. For powerline PLC/dLAN, on the other hand, the CEMPROTEC 32 is currently the only device in our range that makes this exposure visible. If you’re electrosensitive and want to rule out PLC as a possible trigger, it’s a valuable tool.

Before You Buy: What to Know

According to the manufacturer, the CEMPROTEC 32 is a detector, not a measuring instrument. It shows trends and approximate values. For exact figures, you need a meter with a digital display or a building biologist. The unit is calibrated at 20 °C and 45% humidity. Store it in a dry place and keep it out of children’s reach.
