ELECTROMAGNETIC FIELD METER BENETECH GM3120 WAVE TESTER The electromagnetic field meter is used to measure electric and magnetic field radiation. The GM3120 is designed for testing electromagnetic radiation in both indoor and outdoor environments. It features an internal built-in electromagnetic radiation sensor. Measurements are displayed on a digital monochrome LCD screen, allowing users to take appropriate actions based on the readings. TECHNICAL PARAMETERS: Units: V/m (electric field) / T (magnetic field) Accuracy: 1 V/m (electric field) / 0.01 T (magnetic field) Range: 1 V/m – 1999 V/m (electric field) / 0.01 T – 19.99 T (magnetic field) Alarm threshold: 40 V/m (electric field) / 0.4 T (magnetic field) Display: 3-1/2 digit LCD Frequency bandwidth: 5 Hz – 3500 MHz Sampling time: approximately 0.4 seconds Test mode: Bimode synchronous test Over-range indication: Display shows "1" Operating temperature: 0°C to 50°C Operating humidity: Up to 80% relative humidity Operating voltage: 9V Power supply: 6F22 9V battery Dimensions: 63.6 x 31 x 125.8 mm Weight: 146 g Complies with reference standards: GB8702-1988, HJ/T10.3-1996, GB9175-88 DISPLAY INDICATORS: - Electric field measurement result - Magnetic field measurement result - Backlight indicator - Battery level indicator - Sound signal indicator - VPP – peak measurement value - AVG – average measurement value - HOLD – holds the current reading DEVICE COMPONENTS: A.
