Introduction: Simple operation, fast measurement of the electrical appliances, wires and industrial equipment around the intensity of electromagnetic radiation. Test band width can be divided into high-frequency, low-frequency two steps of measurement. Test accuracy, the lowest frequency of measurement of electromagnetic radiation up to 5Hz.Value for money, easy to carry. Designed to meet CE industrial standard. For the environmental electromagnetic radiation testing: bedroom, office, computer room, control room, cable, power lines, monitors, transmitters and other sources of measurement. Used in home electrical equipment, measurement of electromagnetic radiation: mobile phone, computers, televisions, copiers, fax machines, air conditioners and other power sources of test analysis Specifications: Quantity: 1pcs Display readings: Three semi-liquid crystal display Maximum reading low-frequency 1999V/M / High Frequency 1999W/cm2. Level: low-frequency V/m, high-frequency: W/cm2 Measurement time intervals: 0.4 seconds Operation voltage: 9V Power by : 6F22 9V battery (not included) Measure frequency range: 50HZ-2000MHZ Operation temperature: -15C ~ +60C Dimension: Approx. 132mm * 69mm * 29mm
