NR-850 Handheld Nuclear Radiation Detector – LCD Display Radioactive Tester – Geiger Counter – β Y X-ray Detection
Nuclear Radiation Detector (BLUE MODEL)
Links below for a couple of vids about using Geiger counters – this model may not be featured.
Features:
With LCD display, the working status of the nuclear radiation instrument is clear on the display, and you can quickly and accurately read the data you need.
With the function of automatically storing data, even if the power is suddenly cut off, the data will not be lost and can be stored for a long time.
Three alarm methods: sound, light and vibration, which can better remind you and allow you better warning times.
Hand-held portable design, easy to carry and store, can fit in pocket for carrying.
Compared with other models, this NR-850 nuclear radiation detector is greatly improved over basic models.
Has five measurement units: uSv/h, uGy/h, mR/h, cps, cpm.
Specifications:
Material: ABS, plastics
Detecting rays: X, Y, β (hard beta rays)
Dose current rate: 0.01~1000usv/h (10msv/h)
Cumulative dose equivalent: 0.01μSv~500.0mSv
Energy response: 48KeV~1.5MeV≤±30% (for 137CS-)
Sensitivity: 80CPM/uSv (for Co-60)
Relative inherent error:
NR-750≤±15%(137CS1mSv/h) – basic model, only reads uSv/h, uGy/h, mR/h
NR-850≤±10%(137CS1mSv/h) – higher spec Geiger tube, accuracy and stability improved, professional model
NR-950≤±3%(137CS1mSv/h) – professional endurance type product, reduced power consumption up to 30 days continuous measurement.
NR-1050≤±2%(137CS1mSv/h) – best on market professional model, high end imported chip with all of the above.
Alarm threshold:
Dose rate: can be selected at 0.5, 1.0, 1.5, 2.0, 2.5, 5.0, 10.0, 50.0, 100.0μSv/h
Cumulative dose: can be selected at 0.05, 0.5, 1.0, 2.0, 5.0, 10.0, 20.0, 50.0, 100.0mSv
