Radiation measuring device with a 3-axis measuring spherical probe up to 3.5 GHz, measurement value storage, maximum value hold, and averaging. The radiation meter features a 3-axis round probe for detecting electromagnetic radiation. It is suitable for assessing magnetic fields generated by computer monitors, televisions, and industrial equipment such as magnetic separators, electric motors, and gas shielded welding machines. Additionally, it is used for detecting radiation in the areas of Wireless LAN, GSM, and for identifying microwave radiation. With frequencies up to 3.5 GHz, it can also be effectively utilized in the RF range. The three-axis probe eliminates the need for conversions for individual axes. This small, compact radiation meter is ideal for use in both industrial and laboratory settings due to its special features. Simple, fast, and accurate.
