We all know that electromagnetic waves can reduce people's immunity and harm their fitness, so it is especially important to stay away from radiation. This hand-held portable radiation detector can accurately detect radiation and meet the needs of various scenes, making it easy to carry.
22mA average function electric current offers 3 hours multiple 12 days working battery life.
Large measuring range design, which is from 0.00 to 999.00 μSv/h.
Has the clicking noise of a Geiger counter (continuously clicking).
With radiation exposure contact time and duration statistics display.
100 seconds histogram display, radiation dose statistics.
Dose accumulation function (Dose): it can record the dose accumulation since the last time data clearing. Please keep this value no more than 3100μSv within a year, otherwise, the amount of radiation received will exceed the national standard values.
Contactable pollutants counting function (Contact): this number will be added while the device has directly contacted with the pollutants every time. It can be cleared to zero after using ClearData manually.
Radiation exposure time statistics (Exp.Time): this function can help users to record the time which has been exposing under radiation. For instance, the time while using X-rays machine for examination, or the time of making direct contact with radiation pollutants. This data can also be cleared to zero after using ClearData manually.

How to use:
General testing methods: place device against to the testing object, the data is refreshing every 15 seconds (1 test cycle), waiting 60 seconds (after 4 cycles), the reading values should be stable. For marble radiation testing, the suggested testing time will be 5 minutes (considering the background radiation value is very low, so 5 minutes of data collection is necessary for more accurate results).
Surrounding radiation test: place the device 1 meter above the ground, avoiding beta-ray interference on the ground and testing in open areas for 5 minutes. Observe the average readings on the display.
Find the radiation source: change the display to the histogram interface, and scan the object near the back of the machine. Observe the graphical situation and the alarm tone.
Indicator light: every time the yellow light below the screen flashes, it means the Geiger-Müller counter is received one electronic pulse. Every pulse will cause one corresponding clicking noise, and the radiation values are calculated based on the frequency response of the Geiger tube (CPS). The higher the frequency, the larger the radiation receipted.
