Nuclear radiation is a problem that everyone needs to pay attention to because it can za serious consequences, such as disease and even cancer. Our nuclear radiation detector can help you detect nuclear radiation well, so if you need it, come and try it. Characteristics: Za the help of LCD display, the working status of the nuclear radiation instrument is clearly displayed and the necessary data can be read quickly and accurately. Thanks to the automatic data storage function, even in the event of a sudden power cut-off, the data will not be lost and can be stored for a long time. There are three alarm methods: sound, light and vibration, which can better resemble and provide a better experience. Handheld portable design, easy to carry and store, can be put in the pocket for carrying. NR-750 has three measurement units: uSv/h, uGy/h, mR/h, which can meet your daily radioactive detection needs. Technical data: Material: Plastics Radius detection: X, Y, β Current dose rate: 0,00 - 1000usv/h (10msv/h) Cumulative dose equivalent: 0,00uSv-500,0mSv Energy Ranges: 48keV-1,5Mev≤ 30% (for 137Cs-) Language: English, Chinese Sensitivity: 80CPM/uSv (for Co-60) Product Weight: 120g / 4,2oz Package Weight: 200g / 7,1oz Note: The time and date displayed on the screen are used to record and mark the measurement time, not the real time.
