we just develop a new EMF Tester with Dual Testing Functions: the EMF meter can accurately detect and measure the electric field radiation and magnetic field emission at the same time. It also can measure the environment temperature(℃/℉). , High Precision & Sensitivity: reliable for measure electric and magnetic field radiation of mobile phone, hair dryer, computer, TV, printer, attendance machine, refrigerator, etc.

Below photo is for this EMF meter. if any interesting, you can contact with me:
