POROMETISTO ET01Pro EMF Meter with Temperature & Humidity

POROMETISTO ET01Pro EMF Meter with Temperature & Humidity: Features & Buying Guide

The ET01Pro combines three electromagnetic measurements with temperature and humidity monitoring. Those five functions provide separate observations to record during a location survey.

Listed features

• Electric-field, magnetic-field and RF measurements
• Temperature and humidity monitoring
• Color bars and optional audible alerts
• MAX/MIN readings and Data Hold
• Battery-powered package; retailer lists three AAA batteries

What does 5-in-1 mean?

The five functions are EF, MF, RF, temperature and humidity. Microwave and other radio signals fall within RF coverage; they are not separate environmental modes. Record each reading with its unit and do not infer a shared cause merely because several change together.

Before you buy

Confirm the current ET01Pro variant and package. This page describes the same POROMETISTO model listed in our EMF and environment meter guide.

This overview is based on published product information, not a hands-on HauntGears test. Confirm the exact model, current specifications, included accessories and seller terms before ordering.

Using the device during an investigation

Make baseline observations before a session. Note nearby wiring, appliances and transmitting equipment, then repeat unexpected readings with the device in the same position. A response alone does not establish paranormal activity or certify environmental safety.

Read our EMF meter field guide, compare EMF meters, or browse digital recorders for documenting your observations.
