TES-92 ElectroSmog Meter

The TES-92 ElectroSmog Meter is a high-precision, triaxial EMF meter for measuring electromagnetic fields from 50 MHz to 3.5 GHz. It features a backlit LCD, configurable alarms, and manual memory storage for reliable RF safety and environmental monitoring.

  • Measurement Method: Digital, triaxial
  • Directional Characteristic: Isotropic, 3-dimensional
  • Frequency Range: 50 MHz – 3.5 GHz
  • Measurement Units: mV/m, V/m, μA/m, mA/m, μW/m², mW/m², W/m², μW/cm², mW/cm²

Description

The TES-92 ElectroSmog Meter is designed for accurate, 3-axis electromagnetic field measurement across a wide RF frequency range of 50 MHz to 3.5 GHz. Its triaxial isotropic probe ensures non-directional, reliable readings, allowing users to measure EMF levels regardless of orientation. The backlit 4-digit LCD display provides clear visualization of instantaneous, maximum, average, and maximum-average values, while configurable alarms alert users when thresholds are exceeded.

This meter features a manual memory function capable of storing 99 measurement records for later recall, making it ideal for field inspections, industrial safety audits, and RF compliance testing. With a high dynamic range (75 dB) and precise calibration, the TES-92 can measure electric fields from 20 mV/m to 108 V/m and power densities from 1 μW/m² to 30.93 W/m², providing reliable, portable, and safe EMF monitoring. Lightweight (200 g) and compact, it is powered by a 9V battery with over 15 hours of continuous operation.
