Geiger Counter Nuclear Radiation Detector Personal Dose Monitor X-ray Beta Gamma Alarm Device Radioactive Tester Marble Tools

General radiation knowledge:

International standard (our country execute this standard) 1990
Radiation workers: 20mSv/year (10uSv/hour)
Common public staffs: 1mSv/year (0.52uSv/hour)

Fourth Main characteristics:

● Real time measure the dosage ratio, and record the accumulate the dosage at the same time
● It has calibrate functions.
● Dosage ratio alarm threshold, metering alarm threshold all can be freely set (continue and adjustable)
● Able to check the start time of current dosage accumulation.
● It has the timing measure function, able to freely set in 000-999 hours.
● It has over dosage alarm function.
● Able to save the history record information of the recent 10 times measurement.
● It has calendar clock function, able to guarantee the clock normally running after power off.
● Battery power continue monitored and has the battery power icon.
● Chinese and English menu freely shift.
● It has sensor failure reminding function (display screen indicate “Equipment already damaged”)
● If test the radiation dosage exceed the set alarm value under the status that recorder start and screen extincted then the alarm value monitor will automatically alarm. It will automatically jump to radiation measurement page.
