Electromagnetic Radiation Detector High Frequency Radiation Detector (White)

Simultaneous detection of three parameters, radio frequency strength/electric field strength/magnetic field strength
Sound alarm, screen lock/data lock, backlight on, radiation level evaluation, battery power indicator, average/peak value switch
Use three colors to indicate the radiation level, reminding you whether the current radiation level is safe
This product is widely used in kitchens, high-voltage equipment, homes, offices, factories, etc.
Small, light, portable, built-in high-precision chips, practical and reliable to use
With a large and clear color screen and large and colorful font design, it can easily cope with dim and bright environments, giving you a more comfortable experience
Equipped with the current radiation level grading function, 3 different colors correspond to different current radiation levels, which can understand the current environment more accurately and graphically
There is a sound alarm function, when the detected data exceeds the standard, the buzzer will sound an alarm, and there is a mute button to turn off the sound

ET828 2 In 1 2 In 1 Oscilloscope Multimeter 2.4 Inch Color Screen Meter Digital Resistance Frequency Tester 1MHz 2.5Msps Meter

feature:
2.5Msps high-speed sampling, 1MHz analog bandwidth (ACV oscilloscope only), 4000 code digital multimeter.
One-key oscilloscope, there are three waveform scanning modes: Auto/Normal/Single.
The data waveform retention function during measurement can store 100 sets of data and 10 waveforms.
These parameters can be set independently during waveform measurement, such as time base, amplitude, waveform scan mode, etc.
Relative value measurement can effectively eliminate lead resistance, distributed capacitance or interference signals.
The functions of the multimeter include DC/AC voltage/current, resistance, capacitance, frequency, duty cycle, diode/continuity test.
Automatic/manual range switching, real-time data and stored data are displayed on the same screen.
