Description
Overview
GAOTek Radiation Meter with Wide Measuring Range (High Speed) is designed to measure personal gamma and X-ray radiation equivalent dose rate in the range of 0.01 µSv/h ~ 10 mSv/h. It provides high speed with microprocessor technology. LCD digital display, alarm function, low power consumption, four AAA battery, and solid stainless steel shell are some of the other key features of this device. It is used in commodity inspection, radioactive laboratories, metallurgy, hygiene department, and chemical industry.

”.
“MODE” button function:Parameter setting and Validation function.
“▲”, “ ▼ ” button: Configured parameter selection upward or downward
“” button: POWER and Backlight switch function
Power On/Off and Backlight Operation
The automatic startup: The device automatically goes into measurement mode when installing the batteries the first time. Long press the “” button to turn the Search Radiometer on or off. Under measure mode, short press the “” button to turn LCD back light on.
View and Set Parameters
Press the “MODE” button, enter into setup mode when you can view and select the value by the “▼” or “▲” button, then press the “MODE” button to confirm modify and return to setup interface. In the setup mode, if there is no operation in the device for more than 5 seconds, the Search Radiometer will exit setup mode and enter measure mode automatically.
Parameters Setup Interface
Modify Parameters by the “▼” or “▲” button.
Dose equivalent rate (DER ):
1 µSv/h=100 µR/h
1 nCkg-1/h=4 µR/h
Absorbed doses：
1 Gy=103 mGy=106µGy
1 Gy=100 rad
100 µrad=1 µGy
Dose equivalent:
1 Sv=103 mSv=106µSv
1 Sv=100 rem
100 µrem=1 µSv
